Carbide lathe tool insert questions
- Thread starter Reddinr
- Start date
I think the problem with Ebay, particularly with regards to inserts is the counterfeits ones. You know the old saying, if it's too good to be true, it probably isn't.Hit the bay for Kennemetals , Iscars , Carboloys , Valenites etc if you want great old tools at reasonable prices . There's plenty of them out there . Same goes for the inserts .

For reddinr , I may be getting a 16" lathe in the near future , but if not , I could tool you up very well . I'm just waiting before unloading a bunch of stuff . I do have 5 or so Aloris CXAs ready to go . If I get the lathe , I'll be using my FIMS post and holders .

mmcmdl. Thank you. I think you should get the 16" lathe, because, why not? If not, keep me in mind for the CXA stuff. I'll be around.
I've absorbed all the alphabet soup for the inserts, for the most-part and understand some of the ins and outs of the inserts. The online resources like carbide depot etc. are very helpful.
So, I'm gathering that larger insert holders make a difference, which isn't a big surprise I suppose. Any more thoughts on the 1/2" IC vs 3/8" IC question? Seems to me like the larger hold-down screw would have some benefit?
Most of the holders I have are 0.77-0.79" so the 3/4 tooling would fit. But, I think 5/8" might be fine too as more of the set-screw threads will engage and the insert is about 10% closer to the QCTP.
Does anyone know if David's book is available to buy in PDF or EBOOK? I couldn't find it at Amazon in electronic format. I more or less stopped buying paper books after I cleaned out about a quarter ton of technical books and had to basically give them away to make room and declutter recently. (That was a painful process.)

mksj - Yes. I have had some fun removing large chunks of metal all at once with this lathe. I figured I should take advantage of that capability since it is there. I am amazed each time I do it because the lathe just seems like it is doing the impossible and not really breaking much of a sweat. Plus, I love that shade of blue.

Aukai - Can that sheet-metal-thin piece of metal at the bottom of an XL holder really hold a 3/4"? 
Sort-of serious question though. I came across some metric insert holders a while back (20mm I think) that I would have to hydraulic press into a normal CXA holder. The XL's I looked at then seemed like they were pushing the envelope to me as far as the amount of steel left to hold stuff. So, I passed on those at the time. Probably gave up a good deal for no good reason though.
