Set of 6 three-edged countersinks with three anti-rotation surfaces in a drill with improved RAPID CUT geometry 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 ( shank 10mm) Material: HSS-XE - high alloyed cobalt high-speed HSSE steel (68 HRC) Coating: BLUE-TEC - increases tool life, ideal for machining dry or with a minimum of lubricant Standard: DIN335 / DIN335C RAPID-CUT - specially made for use with automatic rapid feed - 30% faster work compared to ordinary countersinks - o 40% longer life of countersinks 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 countersink works as it should. This way of grinding also achieves (compared to milled countersinks) that the cutting edge is smoother and sharper - greater efficiency and lifetime of the tool. 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.

Tvrdokovová 3bA… â „c. taper countersink with hole for interchangeable guide pins Number of pieces: 3 Angle of blade: 90st. Maximum diameter: 40 mm Minimum diameter: 10.0 mm Clamping shank: 3/4 "(19.05mm) Total length: 60mm Material: carbide Usage: Hard steels with tensile strength over 1000N / mm2 gray Cast iron over 240 HB High-chromium stainless steels(V2A / V4A) Acid-resistant steel Titanium and its alloys All other types of steels, cast iron and non-ferrous metals where a long tool life is required. Guide pins are purchased separately - see related products . Also for countersinking Without the middle pin, the centering is given by the geometry of the hole - even with a bad run, the countersink can be damaged by vibration and vibration! Features: Excellent chip removal, do not tip, the resulting surface without scratches, great centering of the tool- holes Countersink grooves are cut with a fine diamond wheel, thanks to which It is harder and smoother to run compared t o conventional countersinks where the grooves are milled.
