Range: Ø61-80 mm (Ø2.40-3.15”)
The economical yet efficient DR-TWIST line provides a near perfect solution for machining large diameters when powerful machinery is not available.
Twisted flutes and coolant holes enable easy chip evacuation and robust body structure with great resistance to torsion.
The drill body is designed to accommodate from 2 to 4 square inserts with four cutting edges each. Once the edge wears out, the inserts can be easily rotated and continue the drilling process. The inserts can be selected from the variety of chip breaker geometry and grades, depending on the application.
This line is an excellent choice when drilling applications include angular/concave/convex points of entry and exit and is suitable for interrupted drilling.
