Features

1. Strong cutter body design

• V shape insert design enables the cutter to have a thick core and insert backing.
• Ensures high productivity and stability.

2. Extremely secure insert clamping

• V shape design prevents insert movement during machining.
• Eliminates premature insert failure, while providing machining stability.

2. Sharp and strong cutting edge for increased productivity

• High productivity and stability are achieved with the unique cutting edge design.

Large rake angle and obtuse fl ank surface provide low cutting force and anti-chipping performance.

Competitor

Large rake angle off ers low cutting force but small cross section area leads to chipping on the edge.
