Ø 14 mm, cutting depth: 30 mm - core drill made of high-performance high-speed steel. Suitable for steel (such as I-beams, large sheets), cast steel, non-ferrous and light metals. An advanced cutting geometry has achieved significantly improved cutting behavior, positively affecting cutting performance and tool life. Optimized cutting geometry for increased machining performance and reduced cutting forces. The chip angles are designed for universal use in various steel grades. Improved chip removal through U-shaped chip ejection. The special geometry of the ejection reduces the thermal load on the HSS core drill, as the heat generated during machining is largely dissipated with the chips. Reduced friction between the HSS core drill and the workpiece through optimized, spiral-shaped guiding phases. Usable in all pillar and magnetic base drilling machines with Morse taper in conjunction with RUKO holder No. 108 302 / 108 303 / 108 315 / 108 316, RUKO EasyLock No. 108 312 / 108 313 / 108 314, or with Weldon shank direct mount such as RUKO magnetic base drilling machine RS5e / RS10.
