It features a 10.30 mm cutting diameter, a 140-degree point angle, and a multilayer TiAlN coating applied at the tip to extend tool life in abrasive and high-heat applications. The straight cylindrical shank measures 12.00 mm in diameter and the overall length is 102.00 mm (4.0157 inches), making it suited for stub-length drilling operations. Coolant-through capability supports chip evacuation and heat control at the cutting zone. This bit is installed and used by machinists and CNC tooling technicians in production and job-shop settings.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for stub-length drilling applications where rigidity and precision are priorities. It handles materials where solid carbide tooling is specified, such as hardened steels, cast iron, and other difficult-to-machine alloys. The Series B051A-CPG designation follows DIN 6537K geometry standards, and the 3xD flute-to-diameter ratio supports applications with a maximum drilling depth of 40.00 mm (1.5748 inches). The right-hand spiral flute configuration with a regular flute type is suited for standard CNC machining center and screw machine applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cut conditions\u003c\/li\u003e\n  \u003cli\u003eTiAlN tip coating reduces heat buildup and extends tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle minimizes thrust and improves entry stability\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for chip evacuation and thermal control\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds core strength while maintaining cutting performance\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K geometry standard ensures dimensional consistency for toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and screw machines that accept a 12.00 mm straight cylindrical shank, conforming to DIN 6537K stub-length drill geometry within the B051A-CPG series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Confirm that the toolholder or collet chuck is rated for a 12.00 mm straight shank before securing the bit. Disengage machine power and release any stored energy in the spindle before changing tooling. Verify coolant-through passage alignment when using internal coolant systems to ensure proper flow at the cutting tip.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 10.30 mm (0.4055 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 102.00 mm (4.0157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 55.00 mm (2.1654 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 40.00 mm (1.5748 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.00 mm (0.4724 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45.00 mm (1.7717 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: 1.76 mm (0.0693 inches)\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 (Tip)\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eCoolant Through\u003c\/strong\u003e: Yes\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: -0.018 to 0.000 mm (-0.0007 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 Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10.5 x 1.2 x 1.2 inches\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: 4150457\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736030642482,"sku":"4150457","price":249.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6047723244c39e297ff48cf30f8b8e5b_ce05f317-a0d4-4dcb-859f-0e6e2760ca8f.jpg?v=1788775506","url":"https:\/\/voomisupply.com\/products\/kennametal-4150457-screw-machine-drill-bit-10-30mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
