Screw, Insert Retaining, SEHT Inserts

The T-15 Torx fit is spot-on, so the wrench seats without any wobble. Used these to swap inserts on my 4663 cutter and they held tight through a heavy pass. Nice to have spares on hand for when one strips.

Finally found the right replacement screws for my SuperFly cutter — the T-15 Torx fit perfectly and the threads seated cleanly on the first try. I appreciated the clear note about matching them to the correct inserts, saved me from ordering the wrong size.

Used these screws with my indexable turning tool and the T-15 torx fit snug, no wobble. The thread engagement felt solid when tightening, and they held the inserts securely during a heavy cut. Exactly what I needed for that cutter.
