Economical 8 edged inserts with light cutting face milling cutter

Light cutting & optimal chip forming insert featuring 8 cutting edges with high positive rake angle

Applications & Features

Face milling

1. High positive rake face mill

• Inserts with a high positive rake provide light cutting actions.

 

2. Three types of inserts are available

3. Designed to ensure machining stability

• Ideal chip forming.
• Better insert reliability with double flank relief.
