Built to DIN 6537K standards, it features a 140-degree split point for accurate centering and reduced thrust, a multilayer TiAlN coating at the tip for heat resistance and extended tool life, and a straight cylindrical shank measuring 10.00 mm in diameter. The 11\/32 inch (0.3438 inch) cutting diameter and compact 3.504 inch overall length make it well suited for high-cycle production drilling environments. Installation and operation are performed by machinists and tool room technicians.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for stub-length drilling operations where rigidity and controlled depth are priorities. The reduced flute length of 1.850 inches limits deflection and improves hole quality in tight fixturing setups. The regular spiral flute geometry and right-hand cutting direction are standard for conventional CNC machining centers, drill presses, and automated drilling equipment. A maximum drilling depth of 1.378 inches (35.00 mm) makes it appropriate for through-holes and moderate-depth blind holes in metals and hard alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in metalworking applications\u003c\/li\u003e\n\u003cli\u003eTiAlN tip coating resists high cutting temperatures and extends tool life between changes\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle reduces walking and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification ensures dimensional consistency for toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders without modification\u003c\/li\u003e\n\u003cli\u003eTapered web configuration maintains core strength across the flute length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers, drill presses, and automated drilling equipment accepting straight-shank drill bits in the 11\/32 inch size range.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Carbide tooling is brittle — do not drop or subject the bit to lateral shock loads, as chipping or fracture can result. Confirm shank-to-holder runout meets machine tolerances before beginning a production run.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/32 inch (0.3438 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.504 inches (89.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.850 inches (47.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.378 inches (35.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.394 inches (10.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.575 inches (40.00 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\u003ePoint Length\u003c\/strong\u003e: 0.058 inches (1.48 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\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0006 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eWeight\u003c\/strong\u003e: 0.02 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: 4150263\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747376202034,"sku":"4150263","price":129.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df17ea1c33c6587bd1c6be1a956ba5b5.jpg?v=1788879155","url":"https:\/\/voomisupply.com\/products\/kennametal-4150263-screw-machine-drill-bit-11-32-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
