Built to DIN 6537K specification, it features a 140-degree point angle for aggressive, self-centering entry and a multilayer TiAlN coating at the tip to extend tool life under high heat and friction. With a 5.10 mm diameter and a compact 66.00 mm overall length, this stub-length drill delivers rigidity and accuracy in tight-clearance setups. The 2-flute regular spiral design paired with coolant-through capability makes it suitable for production environments where chip evacuation and heat management are critical.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for CNC machining centers, drill presses, and screw machine applications in manufacturing and toolroom environments. The straight cylindrical shank and 6.00 mm shank diameter allow secure chuck or collet retention. Its stub-length format reduces deflection, making it a reliable choice for precision hole-making in ferrous metals, alloys, and other materials common to production machining. Professional machinists and toolroom technicians are the primary users of this tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding machining operations\u003c\/li\u003e\n\u003cli\u003e140-degree point angle promotes accurate self-centering and reduces thrust force on entry\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN tip coating improves heat resistance and extends tool life\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip evacuation and thermal management during deep cuts\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification ensures dimensional consistency and interchangeability\u003c\/li\u003e\n\u003cli\u003e3xD flute-to-diameter ratio with tapered web configuration for balanced chip flow and core strength\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production drill bit within the KENNAMETAL B051A-CPG series for screw machine length drilling applications requiring a 5.10 mm diameter in the 5.00 to 6.50 mm size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tooling is installed and changed by qualified machinists or toolroom technicians. Before changing or setting this drill bit, power down the spindle and confirm the machine is in a safe, locked-out state per your facility lockout\/tagout procedures. Secure the straight shank in a properly sized collet or drill chuck to the tool manufacturer's recommended clamping torque for the holder type in use. Verify coolant-through passages are clear and coolant flow is confirmed before initiating a production cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.10 mm (0.2008 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: 28.00 mm (1.1024 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: 20.00 mm (0.7874 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.85 mm (0.0334 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\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\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN Multilayer (TiN 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: -0.012 to 0.000 mm (-0.0005 to 0.0000 inches)\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\u003ePackage Dimensions\u003c\/strong\u003e: 6.7 x 0.8 x 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 4151135\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734592160050,"sku":"4151135","price":124.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0455a284a9659fa1971dde1506b0da0.jpg?v=1788763597","url":"https:\/\/voomisupply.com\/products\/kennametal-4151135-screw-machine-drill-bit-5-10mm","provider":"Voomi Supply","version":"1.0","type":"link"}
