SW and FW – Oil Seal – T9215


Improved surface roughness and long tool life
- The competitor’s wiper insert was unable to provide the required surface roughness, Rz ≦ 4.5μm ,after cutting 200 pcs. FW chipbreaker delivered excellent surface quality even after machining 300pcs and also extended tool life by 1.5 times due to good wear resistance.

Stable machining
- FW chipbreaker with newly developed “two-stage protrusion” design provided better chip control than the competitor, resulting in stable machining.
