RUKO 108240F Tap drill bit set 40 mm TiAIN 1 pc(s)

Diameter 40 mm. Cutting depth: 30 mm - core drill bits made of high-performance high-speed steel with titanium-aluminum-nitride coating. The TiAlN wear protection coating increases the surface hardness of the tool to approx. 3,000 HV/microhardness and the heat resistance to up to 900°C. It is characterized by high toughness as well as high thermal and chemical stability and serves to achieve higher service life and cutting values. Suitable for dry processing due to the TiAlN coating. Particularly suitable for the processing of unalloyed and alloyed steels (up to 1200 N/mm²), high chrome-alloyed steels such as V2A and V4A, as well as steel casting and tough brass.Through an advanced cutting geometry, a significantly improved cutting behavior could be achieved, Which has a positive effect on cutting performance and tool life.+ optimized cutting geometry for increased cutting performance and reduced cutting forces.+ the cutting angles are designed for universal use in different steel grades.+ improved chip removal through U-shaped removal. The special geometry of the cut-out reduces the thermal load on the HSS core drill, as the heat generated during machining is dissipated with the chip as far as possible.+ Reduces friction between the HSS core drill and the workpiece by means of optimized, spiral-shaped guide lugs. Can be used in all column and magnetic stand drills with Morse cone in conjunction with RUKO recording holder No. 108 302 / 108 303 / 108 315 / 108 316, the RUKO EasyLock No. 108 312 / 108 313 / 108 314 or with direct world key recording such as RUKO magnetic stand drill machine RS5e / RS10.
