Multiple Sumiboron pieces are brazed to one insert.
Multi-corner one-use inserts are all-around ground to a G-class precision specification. In addition, all corners are numbered, making it easy to keep track of used corners.
The combination of the newly developed CBN base material and ceramic coating has achieved longer tool life and improved machining accuracy than previous coated Sumiboron products.
It demonstrates excellent performance in high-precision machining of hardened steel and general-purpose cutting, enabling reduction in machining costs.
High-precision material suitable for finishing processes that require surface roughness and dimensional accuracy.
Maintains excellent surface roughness.
