RUKO 108217 Tap drill bit set 17 mm 1 pc(s)

HSS core drill bits with Weldon shank (3/4"). Ø 17 mm

Ø 17 mm, cutting depth: 30 mm - core drill bits made of high-performance high-speed work steel. Suitable for steel (such as T-beams, large-format sheets), cast steel, multicolored and light metals.A significantly improved cutting behavior could be achieved through an advanced cutting geometry. 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.
