Countersink Bits, LLBB HRC89 TiAlN Countersink Drill Bit M35 Cobalt Deburring Chamfer Drill Bit 2-5/5-10/10-15mm (5-10mm) (15-20)

Specification: Material: HSS-Co/M35 Coating: TiAlN Coating Hardness: HRC89 Size: 2-5mm/5-10mm/10-15mm Shank Size: 1/4" Hex Shank Chamfer: 90° Uses: High-speed steel cobalt / M35 TiAIN coating (Suitable for Aluminum, insulation board, PVC board chamfer,steel, aluminum, sheet metal, carbon steel, 304 stainless steel, etc.) - Industrial-grade TiAIN coating (More than 4241and 6542 high-speed steel materials, live longer!) Features: 1. The same containing cobalt high speed steel material, the surface after a TiAIN coating, 3 times can prolong service life. 2. The TiAIN coating super high temperature resistance, can be in the case of without coolant, long time use, suitable for dry type high speed cutting. Industrial Grade TiALN Coating,TiAlN coating surface will form Al2O3 which form a hard protective layer when drilling.(Perfect for high speed drilling) 3. HSS - CO high speed steel after heat treatment + TiAIN coating surface hardness up to 89 degrees. 4. TiAIN coating can do not need to add cooling fluid, more suitable for aerial work where the work is not convenient to add cooling water systems. 5. 90 degree chamfer, CNC CNC, CBN grinding process. 6. Higher accuracy sharper achieve drilling burr 7. Internal chip removal: To eliminate the phenomenon of flying metal shavings Package Included: 1 Piece x Countersink & Deburring Bit
