For Lathe or Mini-Lathe: Testing lower priced 7 Pieces , Carbide Tool CCMT, DCMT, Holders

- Опубликовано: 8 сен 2024
- This is a review of Tool Holders from Banggood (an Asian trading site like Amazon, AliExpress, etc,) using current types of carbide inserts, DCMT, CCMT,CCGX, 16 ER A60, 11 IR A60, MGMN200. This is a set of 7 12 x 12 millimetres holders, 3 for external turning, 1 for parting, 1 for internal threading, 1 for external threading and one for internal boring. The set comes with 1 insert for each bar. The good news is that the replacement inserts are Really affordable as prices starts at about $5 per box of ten up to something like $16 for the bigger ones…
The testing was performed at my Friend’s workshop since he owns a mini-lathe capable of showing what can be achieved in real work conditions on smaller lathes. People with just about any Mini-lathe or up to an Atlas or South-Bend or similar machines will benefit from this complete set of tooling.
The availability of low price carbide inserts makes possible to people that may have problem with sharpening High Speed Tooling, the inserts solution provides a simple way to get up and running very fast without the worry of grinding usual HSS tools.
After performing the test, my impression of this set is very positive, the price versus quality is rather an unexpected positive surprise, we were able to achieve a good level of performance and quality work on different materials like Aluminium, Cold Rolled Steel, Hot Rolled Steel, and, even some very tough Allow containing some Tungsten as an alloying element.

@@pierresgarage2687 Yes I bought the Craftex cx-709 from Busy Bee. I'm just an amateur lol. I'm buying a lot of carbide cutters and holders from Aliexpress, so far so good.
Pierre,
I bought this set following one of your previous reviews. I've used hss for years and wanted a better selection of carbide options for my 13x40 lathe. While I haven't used them all, the external threading tool works great, and the DCMT & CCMT tools/inserts are EXCELLENT! My only complaint is with one of the DCMT tool holders (straight), which doesn't hold the insert tight enough. With the CCMT inserts, taking a 0.050" cut on the radius (0.100" dia) is no problem, and the chip breaks well, even in 17-4PH stainless. I would highly recommend this set.
Hi Robert, Nice feedback about those tools, though,I think the previous review on those were probably from Chrisfrom Chrisb252, but, agreed that those little CCMTs are great sets of toolong at an irresistible price... About the DCMTs, I havent used them much yet, but I'll have a closer look at what you mention...
Thanks for taking time to write the comment, Pierre
Pretty impressive for the price.
Thanks for your comment, indeed, reasonnably priced carbide tooling for hobbyist and less demanding operators..
great share guys , For the price they can't be beat !
Mostly with the super special they still have for a couple more hours... at $35 CDN, its a GREAT deal even better in USD... ;)
I purchased this same set based on a former review. I think that it was Chris at OMS. My only complaint is the the screws were a little soft and it pulled the threads off of a couple of the screws. I purchased some better quality hold down screws and it solved that problem. Thanks for the review.
Simple enough, would you remember the specs for those screws... Possible that some other viewers get the same issues, it would ease the research for the solution... Thanks for your input, Pierre
This is what I got. There are 2 sizes most take the 2.5 MM. So far they seem to be OK.

Wow that was fast...!!! Thanks for quick response, I'll follow up with a few other viewers tha are in need of replacements...
It's not slow, it's not fast, it's half fast :-)
lol...
WOW! The tested product seems good, but I am really impressed with the lathe. Inserts can be usefull on a lathe like this, probably because the speed can be turned up quite a bit, aside from being preformed/ground.
Hi, that little lathe is a nicely made tool, for it's size it performs really good, as carbide feels better when running at higher speeds, mostly on small diameter parts, then, the combination is near ideal...
Thnaks for your comment, Pierre
Great video and good review. It makes me think I'm not running my insert tools fast enough. Will do some trials. All the best Mat
Great and keep us posted on what you find out, I'm curious to know what other users think or get as results... Pierre
Hi Pierre, Nice to see how that little machine handled it, the end mills from China also do well, a good old handmade thumbs up to you and Robert, have a nice weekend
There are surprising in a good sense, got some carbide endmills that I still need to try out, those Endmills I paid for and curious to find out how they perform, mostly that I regularely use alloyed steel and harder materials... Can't promise in the next days but soon enough if I get a minute...
Thanks for your comment, Pierre
Thanks Pierre, Waiting for your review, I think you will discover that the they do a fairly good job
Very similar to the set I reviewed a while ago - overall they seem really excellent value.
Useful review Pierre. :)
Hi Chris,The holders seem the same, the ones you tested were sold with Aluminum inserts, but could be easyly changed for steel type inserts, there are a few nose radiuses available, some of the last numbers in the descriptive are the radius size. Someone will have to look around to get the proper radiusses if really needed.
Now the set is selling arouns 35 CDN$....
This is something nobody can live with out... lol
Yes, you are right. I really need to get me some more inserts when I can. However, what I had when pushed a bit could manage with steel to do some adequate work. For my sins I am often a bit non-fussy over the inserts I use :)
If you get those exact same ones, you'll surely like them, at less than $5 a box it time to take advantage of the big reduction in price... That is if you need them... ;)
Hitting the link here it's 32% off for a limited time....
Thanks - glad you reminded me about the special offer - have ordered a few of what will be most useful. :)
Hi sir. How are you? Would you guys know the weight of this product. I have looked on the page and can't find info on it.
Pierre...it's not easy to teach an old dog new tricks....😃
If He'd be a Monkey I could train him...
Hello Pierre! Thank you for rewiev! I have some (7,8,10,12,16 and 20 mm) "cnc lathes tools" brand boring bars and threading inserts toolholder, and they works fine.
By now lots of tooling is coming out of Asia with a good price and the quality is getting better and better, a little like Japan when they first started, now, Japanese tools and cars are barely affordable due to their high quality...
Absolutely agree. The price\quality ratio of this tools is the best for hobby machine shop like my. But i remember times when quality of chinese tools was shitty :)
Great test. How about a video that shows how to be sure to get inserts that will fit your tool holder, especially the hold down screw.
I asked someone about the specs on the screws, I'll be back as soon as possible on this, good idea about the insert selection... Whenever time allows... Sihgh... ;)
Here some viewer just sent me this...

Thanks.
Wait till the wife sees the credit card bill with hundreds of dollars spent on a website called "BangGood". I would love to hear the explanation for that one....😁😁😁 .Seriously though, they should consider a name change. Those inserts seem to be rather good.
Better than a site called " A Good Bang".... lol
😂😂😂
Pierre...great video! I gotta show this to Bernard cause we buy overpriced inserts! Bonne job !!!!
Hi Bob, I'd be curious to hear from him if he tries those... ;)
I'll get the coffee grinder before,though..... lol
Just subbed after I found your channel. Good content
Welcome to the channel and thanks for the sub, Pierre
this stuff they also use in their own factories, they have an interest to make them decent and a fair price,(such is the way chinese prefer to be self sufficient as possible) many industrial use and common parts and tools are the same, they have become solid and decent performers, (or chinese machining would not get done) to the extend many well known western names would put their name on it and treble the price
Yap...!!! We're asking them to produce quality products at a rock bottom price, they got to use their creativity to the best to get the job done, the problem is when the tooling companies over here gets the goods cheap and multiply the price by 20 times... something is kinda unfair somewhere, and this is why direct export from China is so popular...
Nice review of those tools. I have a 1933 SouthBend 9" that I play with and an Enco just like Kieth's Fenners Rutland I use for gun smithing. Looking for some small carbide I will check them out.
I'm sure that you will enjoy those, they surprised me in a positive way. This quality at that price it's a great purchase, in any case let me have your impressions when you get to use them...
Thanks for your comment, Pierre
I don't like inserts with screws on my lathe tools or my milling cutters. Those looked like they did well though!
I have both and to me there is'n much difference in the way I like working with either, kinda got used to both since the begining...
Nice.... I am assuming that since your topslide is at about 30 deg then to get a 20thou depth of cut you will need to dial in more.
this is all right if you move the compound that would be set at an angle but not if you're using the cross slide, then, the angle don't count.... If it's what you're suggesting.
Thanks for viewing and for your comment, Pierre
A 12mm shank isn't exactly fit for a mini lathe. 8mm is max IMO. Amazing you could get it on center... Cheers
There is a 10 x 10 mm set available also, didn't test it, though... ;)
what alloy was it ?
Aluminium was 6061-t6 and steel was cold rolled.
Cheers, Pierre
Nice video Pierre, I have had good luck with those inserts, and they are cheap enough to buy a lifetime supply ( for a hobbyist) in one order.
Where did the lathe come from? I think the shortcoming is the ball bearings they use rather than taper rollers, but great bang for the buck, cheers mon ami!
For general work or projects those are the best buy for the buck, hard to beat... I'm really surprised in a good way with the results... Thanks, Pierre
The website says 45HRC, seems that several of them were down in the 20s from your testing.:(
I've tested only on the middle of the shank, if I get a spare moment I'll try to make tests in more spots... Although, the RC results aren't critical with those much smaller inserts, since there is no mini or micro lathe strong enough to twist those...
The inner boring bars were well within the best standards and those are the most important ones to get right...
Sure, but if a vendor advertises their product as being XX HRC and they show up much less, it's deceiving at best. Herein lies the problem with imports, the quality is not consistent and the hardness test you did shows that. For people looking for the absolute cheapest tools they can find, hardness is probably not as important.
Depends on the application also, I would be much more critical with some holders destined to big machines and heavy cutting... Then, the parameters are prime concern...
I know this is asking a lot to answer but will these be suitable for a 10" Sheldon lathe? Certainly that is NOT a mini lathe but I'd like to get some carbide tooling for it. As a hobby hack I can't justify spending a ton on tool holders and inserts. Also can anyone tell me if a negative rake might be OK to use as well?
I'm sure you could use those tools, at least for a start, how powerful is your lathe ( ??? HP ) The trick is to adjust the removal to the weakest link in the chain, those tools can still get a decent bite in steel with the proper power to drive it, CCMT inserts can be loaded near half their cutting side, keep your tool holders close from the toolpost holder use minimum extension to minimize flex...
Great news as the inserts for those cost real low price and do a real decent job... ;)
I really don't know why North American turners like the compound permanently offset 29 - 30 degrees. It is not like you are screw cutting every single job. In any case for finer pitched threads say < 1.5mm pitch plunge feeding is not really a problem. By turning the compound back to 0 degrees and you will notice an improvement in machine stability by reducing effective tool overhang and all radial cutting forces are opposed by the cross feed screw only. On light machines like the lathe shown here it is not uncommon for the compound to creep when offset at an angle which will change your set cut. A further benefit is you have an auxiliary axis parallel to Z with and accurately graduated collar making facing to a length easier.
Here the coumpound is mainly used for chamfers or angle cuts, 99.9% of the time I thread entering straight in at 90 degrees, so much faster and easier to manage, normally a threat doesn't nee much more than 3 to 6 passes total at the fastes possible RPMs...
instead of WD40 or kerosene aluminium, try ethanol. I think it works better and is also much cleaner
I know about ethanol but I'm always reluctant to leave a bottle of that in a shop where I aslo do some grind and sometimes pretty heavy Amps welding...
Totally agreed about the kinda bad aftertase of the other products, mostly yhe kerosens based ones...
Here is a page with some good inspiration on what cutting angles to use. NTK Swiss inserts are interesting to learn about. They are designed with smaller DOC in mind, might be optimal for the minilathe although probably not affordable. If you can grind your own instead, I would try using them as a starting point.
www.ntkcuttingtools.com/product/ss_chipbreakers.html
Thanks for the reference. it looks, just like say interesting and relatively easy to grind in a home shop...
ATB, Pierre
Ha, I actually meant to post this on Steve Summers' carbide grinding video. Just as well! I'm hoping someone will take the ideas of NTK Swiss tools and see if they get any mileage on small lathes.
