ULTIMATECUT 4S HSS conical countersink Ø 19 mm, DIN 355, angle 90° - RUKO

The ULTIMATECUT 4S countersink (Ruko-102880) is a high-performance tool designed to deliver exceptional results in a variety of machining applications. Its innovative uneven pitch redefines countersinking, enabling smooth and quiet cutting action that minimizes vibration and ensures perfectly circular holes. Load distribution across its four sharp cutting edges reduces axial and radial forces, extending tool life and minimizing wear.

This countersink is versatile and can be used efficiently with cordless screwdrivers, drills, pillar drills, and CNC machining centers. Its ability to drill holes up to Ø 40.0 mm with handheld machines is a standout feature, enabling previously impossible applications.
