Built to DIN 6537K specifications, it features a 140-degree standard point angle and a multilayer TiAlN coating at the tip that extends tool life in abrasive and high-temperature cutting conditions. The 9\/64-inch (0.1406 inch) diameter is held to a tight tolerance of -0.0005 to 0.0000 inches, making it well-suited for precision bore work. Machinists and toolroom technicians working in CNC, manual lathe, or drill press setups are the primary installers of this bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for stub-length drilling applications where rigidity and minimal deflection are critical. Its compact overall length of 2.4409 inches and short flute length of 0.7874 inches reduce runout and improve accuracy in close-quarter or fixture-mounted drilling. Maximum drilling depth is 0.5512 inches, making it appropriate for through-hole and shallow blind-hole operations in steel, cast iron, aluminum, and similar materials. The straight cylindrical shank (6.00 mm diameter) fits standard drill chucks and collet holders across common machine tool platforms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in metalworking applications\u003c\/li\u003e\n  \u003cli\u003eTiAlN tip coating extends tool life in abrasive and elevated-temperature cutting conditions\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle reduces thrust force and improves hole entry accuracy\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerance of -0.0005 to 0.0000 inches meets DIN 6537K specification\u003c\/li\u003e\n  \u003cli\u003eStub (screw machine) length design minimizes deflection and improves concentricity\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration and regular spiral flute support efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification stub-length drill bit in KENNAMETAL Series B041A-CPG, suitable for use in standard drill chucks and collet holders accepting a straight cylindrical shank of 0.2362 inches (6.00 mm) diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians on CNC machining centers, drill presses, or manual lathes. Ensure the machine spindle and workpiece are secured before inserting the bit into the chuck or collet. Verify runout with a dial indicator before beginning a precision drilling operation. Do not exceed the maximum drilling depth of 0.5512 inches without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 9\/64 inch (0.1406 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point 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\u003eOverall Length\u003c\/strong\u003e: 2.4409 inches (62.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.7874 inches (20.00 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: 0.5512 inches (14.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0229 inches (0.58 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\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\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: 4150185\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730447958322,"sku":"4150185","price":94.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/027550a92e9fb7c9c67a753ee7e2e1a8_f9a7f640-5c17-4166-a905-4063e145fbc5.jpg?v=1788717649","url":"https:\/\/voomisupply.com\/products\/kennametal-4150185-screw-machine-drill-bit-9-64-inch-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
