Built from solid carbide and coated with multilayer TiAlN, this 8.60 mm diameter bit handles cast iron and steel with consistent accuracy. The 140-degree split point with web thinning reduces thrust force and improves centering on entry. With an overall length of 89.00 mm and a 47.00 mm flute length, it fits standard screw machine setups and CNC drilling operations where shorter flute-to-shank ratios improve rigidity and reduce runout. Coolant-through capability supports high-feed, deep-hole cycles without thermal degradation of the cutting edge.\u003c\/p\u003e\n\u003cp\u003eThis bit is sized for production drilling environments including CNC machining centers, turret lathes, and gang drilling fixtures. The 10.00 mm straight cylindrical shank seats securely in standard drill chucks and collet systems. Primary workpiece materials are cast iron and steel, making it well suited to automotive component machining, die and mold work, and general metalworking production lines where consistent hole tolerance and long tool life are priorities. The DIN 6537K specification ensures dimensional conformity for shops running metric tooling standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for superior hardness and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating extends tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with web thinning reduces entry thrust and improves hole location accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-feed drilling and chip evacuation in deep holes up to 35.00 mm\u003c\/li\u003e\n  \u003cli\u003eParallel web configuration maintains consistent core strength along the full flute length\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K specification ensures metric dimensional compliance for production tooling programs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series B976 screw machine length drill bit conforming to DIN 6537K, compatible with standard straight-shank drill chucks and collet holders accepting a 10.00 mm shank diameter.

Before mounting, confirm the spindle or chuck bore is clean and free of chips that could cause runout. Secure the straight cylindrical shank fully into the collet or chuck to the recommended grip depth to prevent pullout under cutting load. Do not exceed the maximum drilling depth of 35.00 mm per pass without retracting to clear chips, particularly in blind-hole applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.60 mm (0.3386 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 89.00 mm (3.5039 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40.00 mm (1.5748 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (Multilayer)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B976\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1499 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2222651\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727575351602,"sku":"2222651","price":242.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba8bbf1e8f248e1a495a353a6deaaf20.jpg?v=1788679564","url":"https:\/\/voomisupply.com\/products\/kennametal-2222651-screw-machine-drill-bit-8-60mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
