Overview

Strong and fatigue-resistant drill body

Each drill body size is individually optimized and has a never-before-seen stiffness to ensure high process security, repeatability, consistent quality and good run-out accuracy. Twisted coolant holes for maintained drill body rigidity and variable chip flutes with optimized shapes for safe chip evacuation.

Optimized insert design

The robust insert seats have three support contact surfaces for less insert movements. The inserts are strong and have a bulk strength that provides extra toughness resulting in unmatched insert tool life. The ground peripheral insert allows for closer hole tolerance, predictability and consistent performance.

For holes up to 7×DC

The innovative drill body and insert designs makes it possible for cost-effective and reliable drilling of deep holes with less demanding hole tolerances. No pilot drilling needed which saves both time and money.

MDI (Modular Drilling Interface)

MDI is a stable and high precision drilling interface. The modular coupling between drill and adaptor allows you to use one size for several drill diameters leading to less tool inventory and lower costs.

Four locating pins allow for high torque transmission and provide an exact cutting edge position and quick and easy set-up.

With two different diameters on shank and adaptor, double centring with high fitting accuracy is possible. In combination with flange and surface contact between drill body and nut, increased stability, good run-out precision and optimal repeatability can be achieved.
