"A chipped tool that sharpens itself" you say, I know what my old apprentice trainer would have said if I'd come out with that line!
He would slap you in the face ....hahaha
Hahaha i dont recommend this method for finishing
@@barrysetzer All good fun :)
I’m quite impressed, but I wanted to see what the bit looked like after the cuts, since they claim it resharpens itself
You kinda seen an example of it before the cut. Think of an arrowhead and the way its sharpened. I believe they are saying when the carbide chips it's in a manner where it maintains a somewhat usable edge albeit very ugly.
Yep! The tool isnt immortal, no tool is. But this one is as close to that as i have ever seen.
he said its sharp like an arrow head… not that it Hones itself. Jagged stuff is sharp, all honed edges are sharp but not all sharp edges are honed.
That's really impressive. I thought for sure on that first cut that sucker was gonna break. Seems like a great endmill.
Gotta admit that i was impressed, too!
I'm only half way thru this vid and I'm like YEs..yes..yES...haha...I'm not the only one that likes to be sadistic with old tooling and still make it work for me like a worn out field horse...love you people and you Titan. At near retirement age, I am a little operation, but I do what I need to with my little cnc's to get by... and I am very proud of you brother. I hope you keep giving us all great stuff. Someday when you don't do this anymore, at least you'll go down in cnc history as a great inspirational name. Bless you man.
Excellent video, I'm sure we all will not actually do that with a tool but this video show highlights just how strong that endmill still is and I'm sure it will be on all our minds for our next project. Thank you Titans of CNC.
Yeah man these things are beasts! Glad you watched, and got the point 100%!!!!
Kennametal makes quality tools. You will pay a little more up front but if used properly, it will make you $ and save you time.
Cant go wrong with Sandvik as well.
We sell them at a low price on our store, see link in description
Absolutely. We run a half inch 5 flute with chip breakers in Titanium that literally don't give up unless we manage to break them. Usually comes shortly after the 2nd flute breaks off. We get so much use out of them there isn't even a point in getting them reground and having to deal with that mess.
I started with Sandvik endmills, but found that kennametal endmills were half the price of the high performance Sandvik ones, and would outperform them by a mile
@@HondaBoy Yes. I was referring to Sandvik milling and turning inserts though.
I absolutely love Sandvik tooling. Have had bad experience with kennametal but that could be just the tooling I had.
Btw I am running manual not CNC.
Needed more background audio of titan lol that's good stuff
I love this guy! My favourite person off the channel 🤣🤣
And that’s exactly Barry in Real Life!!!
Take THAT, Jessie and Trevor 😂
Lol it is hard not to love Barry
The disturbing part is how in character you got 👀
"yo, BRO."
It's easy to get into character when you ARE that character BWAHAHAHA
He's DOWN WITH THE SICKNESS!
I love the blue color of the chips sitting on top of the workpiece. It's really fascinating that there is no pigment there whatsoever, just the depth of the oxide layer.
Why is a scene from the movie Brazil playing in my head?
“Central Services. You rang, sir. Something about your end mill.”
“It’s fine. It’s sharp. I mean, it sharpened itself.”
“End mills don’t sharpen themselves!”
It is go time :)...More of these funny intro video would be awesome to bring some humor to CNC :)...Keep it up...
That’s Barry all the time.
Talking Smack is Mandatory on our Shop Floor
I had a couple old pcd button inserts that was like that, we had ones we used just for aluminum cylinder heads but we occasionally would use them on cast iron heads with stainless pre-combustion chambers on the final pass due to ringing after the the pre-combustion and they would often chip but i discovered the "freshly chipped" edge on some of them left an amazing smooth and shiny finish on alloy heads. 😂
I have discovered that sometimes the "wrong way" works best. Example: pulling out a long boring bar in hardened steel. Trial and error ftw.
Because chips are sharp. For example the knapped edge of a flint or obsidian knife is sharper than steel.
Amazing!
I set up chipped end mills all the time for roughing, unless all that wear happened simultaneously. The tools are engineered for predictable wear.
Do that all the time, ebay carbide scrap section is full of good tools!
Fantastic. Makes a good case to run it till either the tool snaps, fixturing snaps or the machine overloads.
I was thinking the same thing, if the bit doesn't snap, then some bearing or more expensive thing will end up ruined eventually.. Usually an expensive or hard to replace part.. 😅
It's probably a sign of me being a warped tool geek ...But this is outstandingly good 👍👍
I too am a proudly warped tool geek LOL
There are definitely pros and cons involved here. If you're running cheap and easily replaceable parts that you can toss when the cutter breaks and leaves a digger that won't clean or if you're not interested in regrinding this is the way to go! 😃
As always, awesome videos!
U only use those tools to rough material
@@LordOfChaos.x Roughing is when the majority of end mills break. (Not always) but very rarely will you break one finishing if all is right.
@@thefreedomchopper4027 the point is u only use this tool to roughing material
Is not made for finishing pases
@@LordOfChaos.x Ok.
Just use it for roughing
I find that strangely satisfying.....😊
🤯 Don't even know what to say! MUST try these!!!!!!
Love it
Regards from indonesia 🇮🇩
And nice video
🤙🤙🤙🙏😂
Haha Zombie mill goes BRRRR
I want one now!!! :))
I love this video 🤣🤣
Berry this is epic
Hahahaha Thanks man! It's always fun to do videos like this one. I wasn't sure if it would work, but it did! Thanks for watching!
amazing
I hope my boss doesn’t see this, he’s gonna jus assume all endmills are special like this one
Lol save us from bosses 🤣
Just convince him to test this endmill, and maybe you’ll both be happy! Especially if youre gonna buy a different version, anyway. We only showcase tools we believe in, and give the feeds and speeds to make sure everyone who watches is successful if they try doing something similar. Boom!
Hey I noticed the endmill starts off slow to engage in the cut then takes how did you go about doing that?
If the shop replaced endmills as soon as they got like that we would be broke hahaha!
Its the big shoowwww,big goin down toniiiite.
1:45 "like an arrowhead" That's exactly what I thought right at the beginning of the vid when I saw the way it chips. I thought, just like the primordial man sharpened their stone tools.
Then I looked at Barry and I said, yeah, a caveman. He knows his tools.
lol
Me cutta metal.
I have no loyalty to any brand so I will tell this anecdote.
I had to make a 3/16 c-bore .25 deep in 316ss. I used a kennametal 4fl end mill and peck drilled with the endmill. I noticed the c bore opening up slightly (tool was already well worn but not badly chipped). I set up a Kyocera end mill with same geometry and it broke Instantly (I know i was drilling with it but still).
I went ahead and setup up the kennametal again (same tool) and ran 13 more without them opening up anymore pr out of tolerance.
Long story short, the tools are infinitely tougher than others.
Man, they are MONSTERS. Love this comment, because it once again proves the point of this video!
Thank you for these comments!! #Kennametal
Would this be appropriate for a Bridgeport?
I held my breath through the whole slotting process just waiting for the bang.
Dude you gotta admit, that tool is crazy
That was really impressive. I really doubt you'd keep using a tool like that though. More stress on the part and more stress on the machine over the long term. Butwhaddoiknow?
I would imagine surface finish and tolerance are pretty bad though?
Yeah this isnt a method for finishing, just wanted to show how much life was still in this cutter for roughing purposes
its a roughing tool tho
Shoot if only this video came out 8 years ago when I started in the trade. ...
Trainer: are you even changing your tools? They are all chipped!
Me: No! I'm disturbed!!
That rocks!
How about seeing how hard you could push it on a HAAS with linear ways and a CAT40?
Pretty incredible, right! Being new to Titans, I really want to see other machinists get to see for themselves what i have been seeing for myself every day. Let me tell you, these tools blow my friggin MIND.
Simple! Never do 50 taper work on a 40 taper machine!
What da he'll have I just witnessed
It sounds like a brand new tool
And that, sir, is why i wanted to do this video. What you DIDNT see is the demo we had just done with the Harvi series for a large aerospace company here at Titans in 718 inconel. That demo was why i knew this test would be successful.
Charles would you use that end mill in production?
Who's Charles?
Get it bro.
I`ve noticed this on lathe inserts too. Sometimes a lathe insert will chip in such a way that makes cutting easier. Anyone else think companies are incorporating insert edge designs that mimic edge wear characteristics? It's a bit like how web thinning a drill near the chisel point improves its cutting action, by reducing its cutting force.
Do you see an increase in spindle load for the same op once the cutting edges are chipped?
yes, there is a small increase, like 2-5%
@@barrysetzer Thanks for the reply. That's pretty impressive. A few years back I was running an job in Inconel using an indexable high feed mill. Spindle loads were varying from 80% with new inserts to about 120% when they were dull.
@@reverendalosada inconel is tough.
Looks like all of our tools. Good ones are stashed.
I'm thinking of trying a 1/2 inch diameter with .09 corner rad on hot rolled 1018 at .7 depth. Can you guys recommend a good starting rpm and feedrate for that situation? Air blast or coolant? This is on a direct drive 40 taper VF5
is that full slotting at .7 depth?
@@barrysetzer Yeah. Slot is 1.1 wide with .375 rads in the corner so one pass through the middle and then maybe two more depths up to the top of the fillet. Then I finish the radius with a .75 ballnose
If you use a necked tool like 6767818, I would take the slot in 2 depths at 650 SFM and 40 ipm. You need to lead into the material at 20 IPM until the cutter is fully engaged, then go 40. If you use a tool with a longer flute length like 6676426, I would go the full .7" at 30 ipm with the lead in at 15 IPM, and coolant in either case.
@@barrysetzer Thanks! Got them in my cart already. I've been using sandvick r.390 to rough these out for years now. If I can add even one part a day it would be a huge improvement and easily pay for the tools
@@barrysetzer Didn't quite work out for us. The first one broke instantly as we were using a HAAS milling chuck and it seems they are no good for any useful side loads. The second one did ok but was wearing significantly after doing very little work. It cost $90 and did the work of $20 worth of inserts in a Sandvik R.390 before it was unusable. These things are always worth trying though. We are actually having great success with the HAAS HEIX inserted cutters now which are outlasting the Sandvik inserts by a good margin. We are also trying out their HEHF high feed mill and so far it seems to be very productive and a bit safer to run lights out.
"Like an arrowhead"
Next gen from them should be the "Obsidian" line...
That’s insane
i do this sometimes with chipped endmills just cause i don't want to dull a new one
I run some rather large lathes and we used to use Kennametal 2 inch carbide slugs to rough. They were great and lasted but we recently went to a cheaper brand and the quality just isn't there. They really do make quality stuff
Ill tell you whats crazy, until I came to Titans I had never used Kennametal, because for some reason I thought it was all made in china. I didnt realize that they are an AMERICAN company, and 95% of their solid carbide tools are made right here in the US of A
awesome, i had to watch an ad to watch an ad.
Now that was funny. If only all tool vendors did this kind of edit....
I save chipped tools for when I need to remove a bolt head. Or something I know is going to ruin it.
@Berry. Great Actor 😎😀
Dude… That is Barry
Every Single Day in the Shop
@@TITANSofCNC yes I mean in a positive way 😊 Beeing in the shop is one thing. But transfer that accurate to the video is another . Good job
Boom
0:32 rofl 😂😂
The endmill made it's own chipbreakers
How do servo motors like the load?
I wanna see the same video but with turning tools on a lathe😂😂
The pheonix endmill. Where one cutting edge falls, another rises in its place.
LOL I love that analogy!!!! If we hadn't already nicknamed the tool zombie, I would steal that! Along with your YT name LOL facts
@@barrysetzer Before I'd ever seen one of you guy's videos on them I ran some in Titanium and that was my name for them. Hopefully we all can be so resilient through tough times ;)
what is just as impressive is the horses needed to plough that thing throught that block..
❤️
if the tool is sharpening itself wont your slots get smaller down the feed?
Usually your only doing something like this for ruffing. Another tool will do the finish work
Dominic gets it! We just wanted to show that even when you think this tool is DEAD, it still has LIFE! Thus…..its a ZOMBIE
I use these daily .... From another company "GWS" but I am sure Kennametal zombie mill is the same if not better. 1 zombie end mill equals about 4 of our other tools that were not coated with magic 😆
Hahaha i have worked at places where this tool would have been considered “premium” in its current state! I would challenge you to ask for a test tool from your rep, and just see how this performs compared to that GWS tool. If you do, ill shoot you my email so we can laugh at the results later!
EEEEEEEEEE!!!!!!!!! OK !!!! I think i need some of those.
How do you know when to change it?
Oh... I do this all the time.
Hahaha! But not everyone DOES! We just wanted to show the world that you dont NEED to throw this tool away just because it has a little chip in it.
Wow, you guys actually have worn end mills in you scrap bin.....
So how much HP was that cut? :D Thanks for sharing. Charles
Approximately 28 HP. Thanks for watching!!!!
That'll buff right out with a square bastard file.
Daf*ck!?
Haha
Awesome
Thats what im talkin about lol. If i tried that with any other tool, it wouldve been an instant catastrophic failure 😂😂🥂
You can sharpen the carbide tools It’s what I do for a living and currantly doing some tools that have to be within 0.005mm.
5 thousands? Just breathing hot air on a piece of steel will make it expand by that amount. I call bullshit.
@@Mp57navy that’s why all measuring is done on a cmm machine in a temp controlled room at 21deg
I guess thats whats called roughing in the trade ;-)
...
sparks will fly - sharks will cry!
Helluva thumbnail 😳👍🤣
Wow I am surprised by that. Why are you using a sidelock holder? Is this done to show that the tool still works well with less favourable toolholding.
Side lock holders are actually pretty good if you are worried about tools pulling out. In this case, we weren't worried about runnout on the tool, but because the flutes were already damaged we WERE worried about pullout.
2:04 I agree, this is a lot of sickout, wish the guy at work who is picking up CNC would realize that his 1/4in tools that have a 12:1 sickout is way too much, and unnecessary when milling a part with 1in deep features. espescially in a 20 taper machine, its way too much. Can't fix stupid I guess, he does the same thing on the lathe.
Hello.
I have difficulty with some shaft manufacturing. How to contact you? Please share details
I cant imagine a tool that chips away making a very accurate cut from one end to the other let alone cut to cut
That's why you use them for roughing...
Cutting edge technology
Why you dont regrind tools? Its pretty effective and much cheaper than buy new.
What's the load on the machine?
I feel like the disturbed technician fixing it.
Damn that’s a strong spindle lol and said fuck the coolant lol 😂
This appears to work when using a 10" work piece since its rigid enough to stand the brute force. However this certainly won't be care with a 1" workpiece. A dull tool 'forced' through the workpiece will cause distortion.
True! Just showing how amazing these cutters are!
Manual machinists use this endmills all the time.no problem.
Dont you mean to say that “Manuel” machinists do this all the time? Hahahaha i couldnt resist
@@barrysetzer zombies will never get your brains. Brains
Just because you can, doesn’t mean you should. Our intergrex machines would piss over that all day but the VCN’s would say “no thanks” and I certainly wouldn’t abuse my Doosan like that. Might as well throw £‘s down the toilet……
All good… We are just showing what’s possible so many, venture out past 30% of how badly it’s chipped.
Many look at how we run and complain and say our machines will break etc…
But SpaceX, Blue and other customers never complained about the cost saving they got from us… in fact, they still keep calling and we have to turn away the work.
Not saying that’s your mind set…
Just saying, we run hard and come back and kiss parts into spec… which allows us to drop part times and save our customers money.
Now like Morphias from the Matrix we are Opening peoples minds… to venture out and see what’s possible.
@@TITANSofCNC keep pushing the industry forward guys. There are too many stuck in the mud turtles in the world.
@@dominic6634 🤣 yeah, sure.
Thought the harvi iii was the zombie mill
The nickname extends to the whole Harvi lineup!
Barry took the name to Greatness… if only Kennametal would name the Tool This LEGIT Name…
Well... You have other good cutting surface's and this just goes to show how strong carbide is.
Savage
Surface finish will look like ass, though. Fine for roughing. No good for finish milling.
That’s what I’ve seen on Widia Varimill series. No wonder, since it’s Kennametal 😂😂😂
Dude you gotta admit that the quality of the carbide and the design of the cutting geometry is INSANE! We recently demoed this tool for a large aerospace company and i couldnt believe what this thing was capable of.
@@barrysetzer Last week I used Varimill II Long 16 mm dia cutter. Flutes on endmill looks like… totally useless, BUT it really shines on my DMG Mori NH4000 DCG for roughing 😂😂😂
I’m using trochoidal milling… Vc 180 m/min, fz 0,11 mm/t, Ap 65 mm, Ae 0,24 mm. It really kills ISO P3 without any issues like chatter or something…
Really likes that stuff from Widia (which is Kennametal) 👍👍👍
And man, thank you for all awesome stuff you are doing 💥 💥 💥
Gonna ask the boss
I have chipped carbide e.m.'s that keep going on certain jobs.
Dascool beats Blasocut.
Well damn
You can hear it scream in agony
It’s definitely cool to see this tool keep going like that, but I can’t imagine the stress that is being put back into the part. If you were using that tool on a real world application and the part got thin or removed a serious amount of material that part would bow like a potato chip. Nonetheless cool to see it keeps going like that.
Yeah man, we just wanted to show how badass this tool is. We use it every day, but we get alot of comments saying things like “yeah right, now do that 20 times.” Well, how about we START with one that is already beat to hell and show you what IT can do!?! Just feeding the world the red pill to open our minds. I wouldnt have tried that with any other end mill.
Also it's 1018, may as well be aluminum, only in steel fashion.
1018 may be a cakewalk, but we use this endmill every day in inconel, monel, titanium, and worse. We recently did a demo for a big aerospace company off-camera using the Harvi series, in 718 inconel, and it blew EVERYONE’S minds. I gotta tell you, i may have worked for Titan for 6 months now, but I cant believe what these things can do.
That's a tough endmill, but it's soft steel and only straight passes...
Go look at our AerospaceAcademy.com we run this tool in Inconel, Monel, Ti etc
