HSS-CO RUKO 5 cobalt hollow drill bit Ø 30 mm Weldon shank for high precision.

The Ruko-108230E hollow drill bit is designed to deliver exceptional performance when drilling difficult materials, especially high-alloy steels such as V2A and V4A. With a diameter of 30 mm and a depth of 30 mm, this tool is ideal for use in magnetic base pillar drills and bench drills with a Morse taper connection, using adapters 108 302 or 108 303. Its direct connection to RUKO RS 10 type drills ensures optimal compatibility and efficient operation.

The cobalt alloy used in its manufacture gives the drill bit greater heat resistance, resulting in superior performance and a longer service life, even under demanding working conditions.
