Built from solid carbide and coated with a multilayer TiAlN finish at the tip, it delivers hardness and heat resistance required for drilling steel, cast iron, stainless, and similar materials at elevated feed rates. The 140-degree point angle reduces thrust and helps center the bit without a pilot hole. At 89.00 mm overall length with a 47.00 mm flute length, it fits tight-clearance drilling setups common on CNC machining centers and screw machines. Two regular spiral flutes with a tapered web provide efficient chip evacuation. Coolant-through capability supports high-speed applications where heat management is critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production machining, job shop operations, and automated CNC drilling cycles where stub-length rigidity reduces deflection and improves hole accuracy. The straight cylindrical shank at 10.00 mm diameter seats directly in standard drill chucks and collet holders without additional adapters. The 3xD flute-to-diameter ratio and DIN 6537K specification make it a recognized standard in European and North American metalworking applications. It is typically installed by machinists and CNC operators working in precision component manufacturing, aerospace part fabrication, and general metalworking.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating (TiN at tip) reduces friction and extends tool life at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle lowers thrust force and self-centers on flat or curved workpiece surfaces\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design channels coolant directly to the cutting edge for thermal management\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration maintains core strength while supporting chip clearance\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K specification ensures dimensional conformance to recognized industry standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a stub-length solid carbide drill bit in Series B051A-CPG, conforming to DIN 6537K, for use in standard drill chucks, ER collet holders, and hydraulic chucks accepting a 10.00 mm straight cylindrical shank. Suitable for drilling applications within the 8.00 mm to 9.50 mm drill bit size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. The machine spindle must be powered down and the tool holder verified as secure before inserting or removing the bit. Ensure the collet or chuck bore is clean and free of chips before seating the shank to maintain runout tolerance. Follow machine tool manufacturer guidelines and applicable shop safety standards when setting speeds and feeds for carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.10 mm (0.3189 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 (1.8504 inches)\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 Length\u003c\/strong\u003e: 1.37 mm (0.0540 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Multilayer TiAlN, TiN at tip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.015 to 0.000 mm (-0.0006 to 0.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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: B051A-CPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 4151176\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748295901490,"sku":"4151176","price":180.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6047723244c39e297ff48cf30f8b8e5b_27058be0-890a-4433-b0e7-93bbe947fff6.jpg?v=1788891942","url":"https:\/\/voomisupply.com\/products\/kennametal-4151176-screw-machine-drill-bit-8-10mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
