TIAIN RUKO HSS core drill bit Ø 35 mm with Weldon shank for high precision.

The Ruko-108235F HSS TiAIN-FUTURA hollow core drill is a high-precision tool designed for machining demanding materials. With a diameter of 35 mm and a depth of cut of 30 mm, this drill is especially suitable for working with steel beams and high-chromium steels, such as V2A and V4A. Its TiAIN-FUTURA wear-resistant coating, consisting of oven-sintered titanium nitride, increases the surface hardness of the drill to 3000 HV microhardness, allowing for dry operation, unlike other drills that require cooling.

The right-hand cutting design and CBN grinding ensure optimal performance and a long tool life.
