Built from solid carbide with a multilayer TiAlN coating, it delivers the hardness and thermal resistance needed for demanding production environments. The bit measures 8.50 mm in diameter with an overall length of 89.00 mm and features a 140-degree split point geometry with web thinning for reduced thrust and improved centering. Right-hand cutting, two-flute spiral configuration, and a straight cylindrical shank round out the design. This bit is installed by machinists, tool-and-die professionals, and maintenance mechanics working in metal fabrication shops.\u003c\/p\u003e\u003cp\u003eThe 1913488 is suited for screw machine applications and general drilling operations in ferrous workpiece materials including cast iron and steel. Its shortened overall length relative to jobber-length drill bits provides increased rigidity and reduced deflection, making it appropriate for close-tolerance hole production. The straight-cylindrical shank accommodates standard drill chucks and collet systems. Maximum recommended drilling depth is 35.00 mm, and the flute length is 47.00 mm. The bit conforms to DIN 6537K geometry standards, supporting use in environments where dimensional compliance is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness and heat resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating reduces friction and extends tool life at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with web thinning improves centering and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides greater rigidity than jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand, two-flute regular spiral design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for solid carbide screw machine drill bits in Series B966 conforming to DIN 6537K.

Power down and lock out the spindle before securing or removing the bit from the chuck or collet. Verify shank seating and runout before commencing drilling operations. Do not exceed the recommended maximum drilling depth of 35.00 mm in a single pass without appropriate pecking cycles to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.50 mm (0.3346 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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35.00 mm (1.3780 inches)\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\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.40 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eCoolant Through\u003c\/strong\u003e: No\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: B966\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1508 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1913488\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51754022175026,"sku":"1913488","price":167.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38bb980cd13894d951a91bf2f27592c7.jpg?v=1788943019","url":"https:\/\/voomisupply.com\/products\/kennametal-1913488-screw-machine-drill-bit-8-50-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
