Built to DIN 6537K specification, this stub-length bit features a 140-degree standard point angle and a multilayer TiAlN coating at the tip to extend tool life and resist heat buildup at cutting speeds common in production environments. The overall length measures 4.2126 inches, with a 2.3622-inch flute length and a straight cylindrical shank diameter of 0.5512 inches. Machinists and toolroom professionals use this bit where controlled depth and rigid setup are required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for screw machine and short-hole drilling operations in ferrous and non-ferrous metals, hardened alloys, and cast materials. The stub-length design minimizes deflection and improves rigidity in CNC machining centers, drill presses, and screw machines. The 3xD flute-to-diameter ratio and tapered web configuration support chip evacuation in blind and through-hole applications up to a maximum drilling depth of 1.6929 inches. It is sold and used as an individual bit in Series B041A-CPG.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN tip coating reduces thermal wear and extends cutting life\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle suited for flat-bottomed entry and reduced thrust in production drilling\u003c\/li\u003e\n  \u003cli\u003eStub-length design minimizes overhang and deflection for tighter tolerances\u003c\/li\u003e\n  \u003cli\u003eTapered web with regular spiral flute for reliable chip evacuation\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for CNC machining centers, drill presses, and screw machines requiring a 35\/64-inch straight-shank solid carbide stub drill bit conforming to DIN 6537K.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the machine fully powered down and the spindle locked. Verify that the tool holder or collet accepts a 0.5512-inch straight shank before seating the bit. Inspect the cutting edges and coating condition before each use. Follow the machine manufacturer and applicable shop safety guidelines when setting spindle speeds and feed rates for carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 35\/64 inches (0.5469 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.2126 inches (107.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.3622 inches (60.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.6929 inches (43.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5512 inches (14.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.7717 inches (45.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0943 inches (2.40 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\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\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\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: -0.0007 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 4150332\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732548518194,"sku":"4150332","price":206.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/027550a92e9fb7c9c67a753ee7e2e1a8_66ff076e-901f-4c84-a67b-d622f67a0f46.jpg?v=1788744325","url":"https:\/\/voomisupply.com\/products\/kennametal-4150332-screw-machine-drill-bit-35-64-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
