Measuring 0.1065 inches (wire size 36) in diameter with an overall length of 1.9685 inches, it features a 140-degree standard point angle that promotes self-centering and reduces thrust force at entry. The multilayer TiAlN coating extends tool life in ferrous and heat-resistant alloys by reducing heat transfer into the carbide substrate. With two regular spiral flutes and a tapered web configuration, the 4042546 delivers efficient chip evacuation across a maximum drilling depth of 0.4331 inches. Coolant-through capability supports high-speed and dry machining strategies.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for screw machine operations, CNC machining centers, and automated drilling cells where stub-length rigidity reduces deflection in short-reach applications. The straight cylindrical shank with a 0.1181-inch diameter seats securely in standard collets and drill chucks. It is appropriate for machining steel, stainless steel, cast iron, and similar materials in both job shop and high-volume production settings. Installation and operation are handled by machinists and CNC setup technicians following standard tooling protocols.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance beyond high-speed steel alternatives\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating reduces friction and extends tool life in ferrous and heat-resistant alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle promotes accurate self-centering and clean entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports both wet and high-pressure coolant strategies\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration aids chip clearance and reduces walking at entry\u003c\/li\u003e\n  \u003cli\u003eStub length flute geometry (flute length 0.6299 inches) maximizes stiffness and minimizes deflection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for applications requiring a wire size 36 (0.1065-inch) stub-length carbide drill bit with a straight shank, conforming to DIN 6537K specification. Compatible with any drill chuck or collet system accepting a 0.1181-inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the tool changer or quill is in a safe position before seating or removing the bit. Verify collet or chuck bore size matches the 0.1181-inch shank diameter to prevent runout. Do not exceed the manufacturer-rated drilling depth of 0.4331 inches per pass without pecking cycles when drilling blind holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 36\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1065 inches\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 (Multilayer)\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\u003eFlute Length\u003c\/strong\u003e: 0.6299 inches (16.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.9685 inches (50.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1181 inches (3.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1024 inches (28.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.4331 inches (11.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0171 inches (0.43 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.002 to +0.012 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by 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: B976Z\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.013 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: 4042546\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744946159922,"sku":"4042546","price":160.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f6d90035cd1fd88c81b92601bafc035_afa34f1d-916a-421a-ac31-634dfe5e4177.jpg?v=1788862533","url":"https:\/\/voomisupply.com\/products\/kennametal-4042546-screw-machine-drill-bit-size-36","provider":"Voomi Supply","version":"1.0","type":"link"}
