Features
1. Double-sided insert with 6-cutting edges
• TungSixDrill is the first indexable drill in the world to adapt double-sided inserts with 6-cutting edges, reducing the insert consumption for the customers.
2. Low cutting force even with double sided insert
• The cutting forces are almost equal to competitors positive single sided inserts, especially at higher feed rates, thus complementing higher productivity.
3. Enhanced corner of central insert
• The central corner is strengthened by an obtuse angle relief thus increasing the corner strength and reliability.
