@@Zkutmachine cutting properties... hss with the proper geometry will actually cut the softer materials... carbide will push/peel/roll the material... now, with that said, you can grind different primary and secondary reliefs better side rake, you have neutral, positive and or negative top rake etc IMO grinding carbide is waste especially when HSS works beautifully when everything is right.
@@Zkutmachine Anyone saying hand ground HSS is better than carbide for soft material hasn't used anything other than 20 year old carbide inserts. Korloy DCGT 32.52 is an excellent cheap insert for soft stuff. HSS only starts to shine with REALLY soft material like rubber, if you're willing to spend 30 minutes to rough grind, finish grind, hone, and polish each HSS bit on a proper tool grinder.
@ you are 💯 correct!! I’m from the ole school.. I actually have had to grind threading profiles out of tool steel!! Inserts have come a long way!! Thanks for your great input!
@kevind1865 carbide has definitely come a long ways in the least 15 years... nowadays carbide is a little more resistant to chipping when cutting lead etc... you can get a nice finish carbide... no doubt. Hss cuts rubber good... and thats because it cuts, doesnt roll thr material... use that same theory on lead, zinc, different grades of copper and aluminum... Call me old school, a stick in the mud, but, I'll use HSS, or Colbalt... and I'll have a mirror finish with colors... copper you'll see the greens, reds, oranges, purple-ish colors... To each their own... with time comes change, but the old tried and true will always have a place... and when the old ways are forgotten and the new tooling and tech just aren't cutting it, the old true ways will shed light and open new options for those fixed to only new ways.
💯 % use HSS on anything soft such as lead, zinc, copper, etc... cutter geometry is the factor that you're missing. A good light cutting oil is the cherry on-top when surface finish needs to be bright and smooth.
HSS should work fine. Actually, boring old high carbon steel should work too. I've turned tin (pewter) with HC steel and yeah it dulled the tool after a while but it worked fine. Now I need to watch more of your videos!
@@mikesharp6342 I looked on your channel… not one thing about machine work… Let’s just leave that to professionals.. like me. You don’t have to be rude. I’m just asking for you to show me… how YOU do it better!
lead should not wear the cutting edge; carbide works on tool pressure where HHS slices/cuts by tool geometry. Buddy did apprenticeship for Black Clawson making paper machine parts in NYS. Caride finish cut was .007 feed, rough feed was .015
If you really want a carbide insert, try a really high positive, like an MS chipbreaker with a CVD coating. Look for a TiN flavor (the gold color) you want a real sharp insert, like you'd use on teflon or nylon. Works great, high speed, low drag 😎
Lead is a hazardous material so pleased use eye protection and gloves when handling it, especialy when machining it, maybe even a mask so you dont inhale it.
@@busterdavy9769 lol if you think those little strings will suck me in.. that’s pretty funny. But thanks for your concern. 35 plus years in a machine shop… 0 accidents.. that’s a pretty fair safety record. Not one ER visit.
Ohhh that’s right…. You will have some excuse, why you can’t show me YOUR machine work… “ boss won’t let me video” “ we do highly secret stuff” lol show me that you know more than me in a machine shop. I will me waiting
@@Zkutmachine if I choose not to show my skills it doesn't mean I don't have any. Your video suggested to me that you were going to compare a carbide lathe tool with a HSS one. Naturally I expected the HSS to be ground to cut metal. I never thought you would try to cut metal with a knife. I should have paid more attention and not assuming the geometry of the tool.
long sleeves + hoodie strings < awesome
like your tips and tricks
Enjoy all your videos and knowledge Zack, cheers from Florida, Paul
@@ypaulbrown thank you Paul!! And thanks for the sup and watching! 🙏🏻💪🏻
HSS works great on lead. It's your tool. Never seen anybody grind a tool like that for anything, rubber maybe.
@@dondroc1 it doesn’t work “ great” but it would get the job done. Nothing works better than carbide insert.

@@RichFife I do a bit different.. but yiu are correct on tool geometry!📐 💪🏻💪🏻

@@transmundanium I appreciate you!!
You can cut lead or babbit with a dang craftsman screwdriver if you put the correct geometry on it!
@@mikesharp6342 helll yeah!!

I think this is the first vid ive seen turning lead
@@nathandevine552 badass!! I do a bunch..
Man be careful with those hoodie strings next to rotating tools
@@DerDanachDenkende I will thank you.
Good way to get pulled into the lathe with hoodie strings👎🏿👎🏿👎🏿

@@Zkutmachinethose little strings absolutely will suck you in.
@@danwilliams6175 again… 35 plus years.. I’m a machine shop. No accidents.. not one ER visit. In 35 years!!!! Safety record is intact.
@danwilliams6175 on liveleak, saw a guy get sucked in by a strip of emery cloth. Wrapped around the stock like a meat and denim fruit rollup.
I wouldn't trust the opinion of anyone who calls a turning tool a knife.
@@marley589 lol it’s a knife…. It’s cuts rubber… I forgot more about machine work… than. YOU know.
Obviously you forgot a whole lot! 😂@@Zkutmachine
@@mikesharp6342 where is your videos at??? I would like to see??
