Set of 6 three-edged countersinks with three flats against rotation in the drill Angle: 90° Set Contents : 6.3mm (stem 5mm) 8.3mm (stem 6mm) 10.4mm (stem 6mm) 12.4mm (stem 8mm) 16.5mm (stem 10mm) 20.5mm (stem 10mm) Material: HSS-XE - high-alloy cobalt high-speed HSSE steel (68 HRC) Coating: BLUE-TEC - increases tool life, ideal for dry machining or with a minimum of lubricant Standard: DIN335 / DIN335C The cylindrical shank has 3 flats preventing rotation in the chuck -> high efficiency Karnasch countersinks are precisely ground with a CBN wheel, which guarantees that the cutting edge of the countersink is always the highest point and the countersinking works as it should. Grinding in this way also achieves (compared to milled countersinks) that the cutting edge is smoother and sharper -> greater efficiency and tool life. The result of this grinding is perfect chip removal, trouble-free work, a perfect surface without scratches and a perfectly centered recess. Supplied in a plastic case.
