3bř. conical countersink made of cobalt sintered steel, finely ground with CBN disc Maximum diameter: according to the selected variant Minimum diameter: see product description for selected variant Clamping shank: see product description for the selected variant, with three anti-rotation surfaces Edge angle: 90st. Overall length: see product description for selected variant Coating: BLUE-TEC, increases the life of the countersink when cutting with very limited cooling (spray, paste), as well as when cutting dry Material: HSSE-PM - sintered powder cobalt high speed steel Standard: DIN335 C Usage: Alloy steel with tensile strength up to 1400N / mm2 Stainless steel with tensile strength up to 900N / mm2 Gray cast iron Aluminum alloys with silicon content> 10% Copper, brass, plastics Hardox, Hastelloy, Inconell, Nimonic and other special alloys Features: Excellent chip evacuation, cutting edge, resulting surface without scratches, excellent tool-hole centering The countersink grooves are ground with a CBN wheel, which makes the cutting edge sharper and smoother compared to conventional countersinks where the grooves are milled. The cutting edge is always the highest point of the diameter, ie during countersinking the material does not rub against the wall of the countersink, which reduces the required cutting force and also reduces the heat generated -> which increases the service life of the countersink.

Overall length: see product description for selected variant Coating: BLUE-TEC, increases the life of the countersink when cutting with very limited cooling (spray, paste), as well as when cutting dry Material: carbide (diameter 4.3 to 11.5 all-carbide design, 12.4-31 mm carbide head with brazed shank made of tool steel) Standard: DIN335 C Usage: Hardened steel up to 50 HRC Alloy steel with tensile strength up to 1400N / mm2 Stainless steel with tensile strength up to 900N / mm2 Gray cast iron Aluminum alloys with silicon content> 10% Copper, brass, plastics Hardox, Hastelloy, Inconell, Nimonic and other special alloys Features: Excellent chip evacuation, cutting edge, resulting surface without scratches, excellent tool-hole centering The countersink grooves are ground with a fine diamond wheel, which makes the cutting edge sharper and smoother compared to conventional countersinks where the grooves are milled. The cutting edge is always the highest point of the diameter, ie during countersinking the material does not rub against the wall of the countersink, which reduces the required cutting force and also reduces the heat generated -> which increases the service life of the countersink.

Carbide conical countersink for Hardox Maximum diameter: according to the selected variant Blade angle: 90°. Number of blades: 5 (with a diameter of 10.4 mm there are 4 blades) Other dimensions - see the attached catalog sheet Coating: BLUE-TEC, increases the life of the countersink when cutting with very limited cooling (spray, paste), as well as when cutting dry Material: carbide (diameter 10.4 all carbide design, 12.4-31mm carbide head with brazed tool steel shank) Usage : Hardox 400, Hardox 450, Hardox 500 Hardened steel up to 60 HRC Alloyed steel with tensile strength up to 1400N/mm2 Stainless steel with tensile strength up to 900N/mm2 Gray cast iron Graphite, carbon and plexiglass, reinforced plastics Hastelloy, Inconell, Nimonic and other special alloys with strength above 850 N/mm2 Warning - carbide / carbide countersinks should only be used on NC/CNC machines. Properties : Excellent chip evacuation, the edge does not chip, the resulting surface is scratch-free, excellent tool-hole centering The countersink grooves are ground with a fine diamond wheel, making the edge sharper and smoother compared to conventional countersinks where the grooves are milled. The cutting edge is always the highest point of the diameter, i.e. when countersinking, the material does not rub against the wall of the countersink, which reduces the necessary cutting force and also reduces the generated heat -> which increases the service life of the countersink. Cat. no. : 403045 / 40 3045

Crown drill / puncher / drill bit bi-metal, jigsaw Average: according to the selected variant Max. drilling depth: 38mm Catalog number: 20.1500 Cutting conditions - see attached catalog sheet Material: HSS Co8 (high speed steel with 8% cobalt) Fine tooth - toothing 4/6 " Suitable for drilling in: alloy and common steels, stainless steel, non-ferrous materials and light metals * From a diameter of 160 mm, drilling into metal is not recommended - only non-metallic materials, wood, plastic, etc. HSS Co8 bimetal jigsaw. Fine gearing is very well suited for metals. It ensures a quieter operation and requires less effort. Due to less heat generation during cutting, the service life is extended, especially for metals. Suitable for alloy and common steels (up to 750N / mm2), high chromium steels such as stainless steel, acid-resistant steels, non-ferrous materials and light metals.
