Re: Carbide Lathe Tooling Advice

Another supporter of latheinserts.com /ccmt/ccgt inserts here.

For general OD/ID turning/boring my personal favorites are 32.52 CCMT's with the LF chipbreaker (http://www.maritool.com/Indexable-To...uct_info.html). I prefer the 32.52's over the 32.51's for the larger radius, (.032 v .016), this makes the radius a little stronger and gives better finish, as long as you can stand the .032 radius on your parts, or the time it takes to remove it (not much).

The CC_T geometry is relatively common, and has positive rake, which is desirable for aluminum and lower horsepower machines. You can find these inserts all over the place, you can even find great deals on name brand 10pks on ebay. Used properly, CC_T inserts will last a very long time in aluminum, I think I got at least 500-700 gears out of each edge on mine.

With whatever insert types you choose, I strongly recommend you standardize inserts across all your tooling. Having one insert type for your turning/boring tools really helps keep you productive, since you can swap inserts across tools if you run out or break inserts. The SCLC series, for holding CC_T series inserts are my favorite.

For cutoff tools, the self-locking GTN series inserts and holders are my favorite. These make a shocking difference over standard HSS parting blades.
