Built from solid carbide and coated with TiAlN at the tip, it is engineered for high-speed drilling in hard or abrasive workpiece materials where tool life and hole accuracy are critical. The 140-degree split-point geometry reduces thrust and self-centers on contact, minimizing the need for a center punch or pilot hole. Overall length is 2.5984 inches (66.00 mm), with a straight cylindrical shank of 0.2362 inches (6.00 mm) diameter. This bit is intended for use by machinists and toolroom technicians operating CNC machining centers, drill presses, and screw machines.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for close-tolerance production drilling in metalworking environments, including job shops, contract machining, and OEM manufacturing operations. Its stub-length design increases rigidity and reduces deflection in short-reach applications where standard-length bits would flex or chatter. The 2-flute regular spiral geometry provides efficient chip evacuation in through-hole and shallow blind-hole applications. Maximum recommended drilling depth is 0.7874 inches (20.00 mm), consistent with the 3xD flute-by-diameter ratio of the Series B041A-CPG design. No coolant-through feature is present; external coolant or cutting fluid application is standard practice for this bit type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior hardness and wear resistance in metalworking applications\u003c\/li\u003e\n\u003cli\u003eTiAlN tip coating reduces heat buildup and extends tool life in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle self-centers and reduces drill thrust\u003c\/li\u003e\n\u003cli\u003eStub-length design increases rigidity and minimizes deflection in short-reach setups\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of -0.0005 to 0.0000 inches ensures close-tolerance hole sizing per DIN 6537K\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production drill bit for use in standard drill chucks and collet systems accepting a 0.2362-inch straight shank.

Ensure the machine spindle is fully stopped and locked out before loading or removing the bit from the chuck or collet. Verify shank seating and runout with a dial indicator prior to production use, especially in tight-tolerance applications. Apply appropriate cutting fluid externally, as this bit does not feature coolant-through capability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2130 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5984 inches (66.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1024 inches (28.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches (6.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.7874 inches (20.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0355 inches (0.90 mm)\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\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: B041A-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: 0.05 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: 4150217\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743845253426,"sku":"4150217","price":83.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1fa35c5b75fd48089f63da1226e4581c.jpg?v=1788850308","url":"https:\/\/voomisupply.com\/products\/kennametal-4150217-drill-bit-size-3-solid-carbide-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
