General Purpose Coated CBN Grade for Hardened Steel

A new CBN tool grade to revolutionise the machining of hardened steels.

• Even under high load conditions, high wear resistance can be obtained to increase machining performance.
• Cutting edge strength offering longer tool life even during unstable or interrupted machining.
• New BM insert series with breaker for ideal chip control.

Features

Wide application range

• For machining of hardened steels, it can be used from continuous through to interrupted machining.
• High crater wear resistance makes it possible to carry out large depth of cut machining such as removal of carbonized layers.
• Available with 3 variations of honing.
FS (Continuous cutting)
GA (General purpose cutting)
TA (Interrupted cutting)

Cutting Performance (1)

Wear resistance

BC8020, offers high wear resistance for high load continuous cutting.

Toughness

BC8020 with high wear resistance results in longer tool life for continuous cutting.

Breaker Insert

Wiper Insert

Effective for machining workpieces with low rigidity

The new wiper shape not only shortens machining time and maintains surface roughness with a high feed rate, it enables machining of areas where vibration typically prevents other tools from working.
