1. S-7 Tool Steel.
S-7 tool steel is both hard and tough. We through-harden it to 56 RC and double-temper it for maximum toughness.
2. Left-hand Engagement Threads.
L-H external threads prevent C-Sert from backing out if you need to remove a bolt.
3. Chip Relief, Lands & Flutes.
Chip relief reduces tool pressure. Lands support the tapping teeth and flutes clear chips.
4. ACME Profile Threads.
Heavy duty ACME profile threads create interference tension to prevent pull-out.
5. Internal Die Threads
grip to prevent strip out.
6. Integral Pilot.
Ensures C-Serts start straight
