RUKO HSS 90º conical countersink Ø max. 63 mm DIN 335 form C

The Ruko-102140 is a high-precision tapered countersink, designed according to DIN 335, with a 90° countersinking angle and a maximum diameter of 63 mm. This tool features a split-point cutting edge compliant with DIN 1412 C, allowing for a more efficient and precise start. Its 118° cutting angle and 20/30° taper angle ensure optimal performance in a variety of applications.

CBN (Cubic Boron Nitride) grinding and the ingenious chip flute design minimize noise, vibration, and burr formation, guaranteeing a clean and professional finish. This countersink is ideal for working with non-ferrous metals, steel, thermoplastics, and hard plastics, as well as sheet metal up to 4 mm thick.
