Built from solid carbide and coated with TiAlN at the tip, this bit delivers hardness and heat resistance suited for cutting ferrous and non-ferrous metals, stainless steels, and high-temperature alloys. It has a 41\/64 inch (0.6406 inches decimal) cutting diameter, a 140-degree split-point angle for accurate self-centering entry, and an overall length of 4.8425 inches. The straight cylindrical shank and regular spiral flute geometry make it compatible with standard drill chucks and CNC machining centers. Machinists and tool-and-die professionals are the primary users of this bit.\u003c\/p\u003e\u003cp\u003eThis bit is built for short-reach, high-rigidity drilling applications where stub length reduces deflection and improves hole location accuracy. Typical use cases include production drilling on CNC machining centers, drill presses, and screw machines in job shop and production environments. The 3xD flute-to-diameter ratio and tapered web configuration support chip evacuation in moderate-depth holes. It is suited for applications requiring tight diameter tolerances, as the bit holds a diameter tolerance of -0.0007 to 0.0000 inches. Coolant-through is not supported on this model.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance for hard-material drilling\u003c\/li\u003e\n\u003cli\u003eTiAlN tip coating enhances heat resistance and tool life at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree split-point angle reduces thrust force and improves centering on entry\u003c\/li\u003e\n\u003cli\u003eStub (screw machine) length minimizes overhang and deflection for tighter hole tolerances\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and ER collet systems\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry promotes consistent chip flow in through and blind holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement in KENNAMETAL Series B041A-CPG and suitable for use in any CNC machining center, drill press, or screw machine accepting a 0.7087-inch straight shank.

Solid carbide tooling requires a rigid, low-runout tool holder — excessive runout will cause premature chipping or breakage. Follow the machine manufacturer and ANSI B11 series safety standards for drill press and machining center operation. Inspect the shank and collet bore for debris or damage before seating the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 41\/64 inch (0.6406 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.8425 inches (123.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.8740 inches (73.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.0079 inches (51.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.7087 inches (18.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8898 inches (48.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.1109 inches (2.82 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\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 4150362\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51753347088690,"sku":"4150362","price":413.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/679421a6fc3dbc0d3be7152c01284a68.jpg?v=1788935683","url":"https:\/\/voomisupply.com\/products\/kennametal-4150362-41-64-in-stub-drill-bit-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
