It features a 4.60 mm diameter with a 140-degree standard point angle and a multilayer TiAlN coating applied at the tip for extended tool life and heat resistance. The overall length is 66.00 mm (2.5984 inches), the flute length is 24.00 mm (0.9449 inches), and the straight cylindrical shank measures 6.00 mm in diameter. With a tapered web configuration and right-hand cutting direction, this bit is built for precision drilling in production environments. It belongs to the KENNAMETAL Series B051A-CPG and conforms to DIN 6537K specification.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for CNC machining centers, screw machines, and production drilling operations where stub-length rigidity reduces deflection in short-reach setups. The 3xD flute-to-diameter ratio and coolant-through capability make it appropriate for drilling steel, stainless steel, cast iron, and similar ferrous materials in both job shop and high-volume production environments. Licensed machinists and toolroom technicians working with precision components are the primary users of this tool.\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 material drilling\u003c\/li\u003e\n  \u003cli\u003eTiAlN multilayer coating at tip for improved heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust and improves chip formation on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal flood or mist cooling during deep cuts\u003c\/li\u003e\n  \u003cli\u003eStub (screw machine) length improves stiffness and reduces runout in tight setups\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production drill in the KENNAMETAL Series B051A-CPG, fitting drill bit size range 3.50 mm to 5.00 mm (0.1500 to 0.2000 decimal inch) across compatible toolholders accepting a 6.00 mm straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians in a machine tool environment. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the bit from the chuck or collet. Use a properly sized collet or drill chuck rated for the 6.00 mm shank diameter to prevent slippage. Verify coolant-through passages are clear before engaging the spindle if using internal coolant delivery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.60 mm (0.1811 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (2.5984 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 24.00 mm (0.9449 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.4173 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 17.00 mm (0.6693 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.76 mm (0.0299 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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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\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: TiAlN Multilayer (Tip)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches (-0.012 to 0.000 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B051A-CPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 4151127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749250007346,"sku":"4151127","price":124.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6047723244c39e297ff48cf30f8b8e5b_1a9b2a84-342e-4f3a-84a7-bd408d8b9335.jpg?v=1788903594","url":"https:\/\/voomisupply.com\/products\/kennametal-4151127-screw-machine-drill-bit-4-60mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
