Built to DIN 6537K standards, this right-hand cutting bit features a 140-degree point angle and a multilayer TiAlN coating at the tip for extended tool life under demanding cutting conditions. The 10.20 mm diameter and 102.00 mm overall length make it well suited for precision holes in tight setups where a shorter drill body reduces deflection and improves rigidity. Two regular spiral flutes provide efficient chip evacuation. It is installed and operated by machinists and tool-and-die professionals on CNC machining centers, drill presses, and similar equipment.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for stub-length drilling operations in ferrous and non-ferrous metals, alloys, and similar materials where a 3xD flute-to-diameter ratio meets the depth requirement. It performs best in applications demanding tight hole-diameter tolerances, with a drill bit diameter tolerance of -0.018 to 0.000 mm. The straight cylindrical shank accommodates standard tool holders and collet chucks sized for a 12.00 mm shank diameter. Series B041A-CPG designates its family within the KENNAMETAL solid carbide stub drill lineup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in metal drilling\u003c\/li\u003e\n\u003cli\u003eTiAlN multilayer coating at the tip extends tool life and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eStub (screw machine) length body minimizes deflection in short-reach setups\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design promotes efficient chip clearance\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 B041A-CPG series, suitable for use in standard straight-shank tool holders and collet chucks accepting a 12.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists following established shop safety procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify that the tool holder or collet chuck is clean and within proper runout tolerance before securing the shank. Do not exceed the maximum drilling depth of 40.00 mm for this stub-length configuration without re-evaluating setup rigidity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 10.20 mm (0.4016 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: 1.74 mm (0.0686 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 Multilayer (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\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\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: -0.018 to 0.000 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\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\u003ePackage Weight\u003c\/strong\u003e: 0.25 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: 4150178\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731628687666,"sku":"4150178","price":171.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef519d90b4870636b2a2dcf7612e6810.jpg?v=1788733342","url":"https:\/\/voomisupply.com\/products\/kennametal-4150178-drill-bit-10-20mm-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
