Built to DIN 6537K standards, it carries a 140-degree split-point geometry that reduces walking and improves chip evacuation on entry. The TiN tip coating extends cutting-edge life under demanding production conditions. At 2.5984 inches overall length with a 1.1024-inch flute, this compact drill is built for rigid setups where a shorter stick-out minimizes deflection. Machinists, tool-and-die shops, and CNC operators working in aerospace, automotive, or general metalworking applications are the primary users of this series.\u003c\/p\u003e\u003cp\u003eThe 4150212 is suited for stub-reach drilling in fixtures, jigs, and machine tools where clearance is limited and hole accuracy is critical. The straight cylindrical shank measures 0.2362 inches in diameter and seats directly into standard collet chucks or drill chucks without additional adapters. With a maximum drilling depth of 0.7874 inches (20.00 mm) and a 3xD flute-to-diameter ratio, this bit handles through-holes and blind holes in steel, cast iron, aluminum, and similar workpiece materials in production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and heat resistance beyond high-speed steel alternatives\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust force and minimizes entry burrs on metallic workpieces\u003c\/li\u003e\n\u003cli\u003eTiN tip coating at the cutting edge extends tool life in repetitive production drilling\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification ensures dimensional conformance for interchangeable tooling programs\u003c\/li\u003e\n\u003cli\u003eTapered web configuration promotes chip flow and reduces core thickness at the tip\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard collet and drill chuck systems without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-spec replacement or production drill in the KENNAMETAL Series B041A-CPG stub drill program, compatible with standard straight-shank collet chucks and drill chucks accepting a 0.2362-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation of solid carbide drill bits should be performed by qualified machinists or CNC operators familiar with cutting tool setup and speeds-and-feeds selection. Ensure the machine spindle and chuck are fully powered down and locked out before loading or removing the bit. Inspect the shank and collet bore for chips or contamination before seating to avoid runout. Solid carbide is brittle compared to HSS — avoid side loading, interrupted cuts without proper parameters, or dropping the tool on hard surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2010 inches\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 Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0334 inches (0.85 mm)\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\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\u003ePoint Type\u003c\/strong\u003e: Standard\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: TiN (Tip)\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\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B041A-CPG\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\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: 4150212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732719993138,"sku":"4150212","price":83.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46a547ec47d92364366244010b9f1a1b.jpg?v=1788746009","url":"https:\/\/voomisupply.com\/products\/kennametal-4150212-stub-drill-bit-size-7-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
