ULTIMATECUT 4S HSS DIN 355 90°

The ULTIMATECUT 4S countersink is a high-performance tool that represents the best performance in all disciplines. It can be optimally used in manual applications with a cordless screwdriver or drill, in column drills, and in CNC-controlled machining centers.

The uneven step of the new ULTIMATECUT 4S countersink is a key component in the redesign of how countersink holes are made, producing a smooth and extremely quiet cutting action, eliminating vibration marks and creating a perfectly circular hole. The cutting loads are distributed on 4 sharp cutting edges, significantly reducing axial and radial forces, to reduce wear and increase the tool's lifespan. This unique cutting action also allows for comfortable and efficient use of the available range of sizes to drill holes up to Ø 40.0 mm using manual or pistol drilling machines. Until now, this countersink diameter was not possible with a manual drill. The range from Ø 10.4 mm to the largest Ø 40.0 mm can be efficiently used and is recommended for all types of drilling machines.

The specially developed 4 cutting edges in combination with the uneven step make the ULTIMATECUT 4S countersink a universal all-rounder.
