HSS TiAIN RUKO Ø 60 mm core drill bit with Weldon shank for high precision.

The Ruko-108260F HSS TiAIN-FUTURA hollow drill bit is a high-precision tool designed for drilling demanding materials such as steel beams and high-chromium steels, including V2A and V4A. With a cutting depth of 30 mm and CBN grinding, this drill bit offers exceptional performance under severe working conditions. Its TiAIN-FUTURA wear-resistant coating, consisting of oven-sintered titanium nitride, increases the surface hardness of the drill bit to 3000 HV microhardness, allowing for dry use, unlike other drill bits that require cooling. The Ruko-108260F is designed for right-hand cutting and is compatible for direct use in RS 10 drills, as well as RS 20, RS 30, and RS 40 models with adapters 108 302 (CM2 Morse taper) and 108 303 (CM3 Morse taper).
