I needed a sharp 60° triangle for some light finishing work, and these TPC-322 inserts with the 11° relief cut cleanly without hogging the material.

William ★★★★★

The 60° point on these inserts cuts cleaner than anything I've had in the holder, and the 11° relief makes it a breeze to sneak into tight spots. For the price of a good sandwich, I've got enough edges to keep my lathe busy for months.

Matthew ★★★★★

Finally got around to using these as a finishing pass on mild steel and the 11° relief really cleans up the cut without chattering. The lack of a chip breaker means you have to watch your depth of cut, but for the price per edge it's a solid deal.
