- Micro precision drilling from micro holes.
- GET RID OF reamer after all.
- Suitable for a wide range of materials including stainless steel, Inconel, Hasteroy, and Kovar.
- Originally developed cutting edge form for chipping and wear resistance.
- Thinning for decreasing thrust load, reducing work hardening and welding.
- Precision shank tolerance of 5μm(+0/-0.0002”).
