ULTIMATECUT 4S HSS tapered countersink Ø 40 mm, DIN 355, 90° angle

The ULTIMATECUT 4S tapered countersink (Ruko-102894) is a high-performance tool designed to deliver exceptional results in a variety of machining applications. Its innovative uneven pitch redefines how countersinking is done, providing a smooth and quiet cutting action that minimizes vibration and ensures a perfectly circular finish. This countersink is ideal for use with cordless screwdrivers, drills, pillar drills, and CNC machining centers, allowing you to drill holes up to Ø 40.0 mm, a diameter previously impossible with hand tools.

Distributing the cutting loads across its four sharp cutting edges significantly reduces axial and radial forces, which not only decreases wear but also extends tool life.
