The black oxide and gold coating reduces friction and helps resist heat buildup during cutting. At 5.2400 inches overall length with a 3.4300-inch flute, this bit is designed for production and general-purpose drilling in steel and cast iron. It is sold individually and suited for use in drill presses, CNC machining centers, and hand-held power drills by machinists, pipefitters, ironworkers, and maintenance mechanics.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is intended for drilling into steel and cast iron in both industrial and commercial maintenance settings. The straight cylindrical shank with three flats fits standard drill chucks securely. The regular spiral flute and tapered web configuration promote chip evacuation in moderate-depth holes. Typical applications include structural steel fabrication, mechanical assembly, and general metalworking where consistent hole diameter tolerance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering and reduced thrust  -  no pilot hole required\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction rated for heavy-duty grade drilling\u003c\/li\u003e\n  \u003cli\u003eBlack oxide and gold coating for reduced friction and heat resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral flute for effective chip removal\u003c\/li\u003e\n  \u003cli\u003eTapered web with 3xD flute-to-diameter ratio for rigidity in deeper cuts\u003c\/li\u003e\n  \u003cli\u003eStraight shank with three flats for positive chuck engagement\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0010 inches for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style heavy-duty replacement or direct-use jobber drill bit for applications requiring a 10.50 mm straight-shank HSS drill in steel and cast iron workpieces, conforming to DIN specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall into a keyed or keyless drill chuck, tightening securely against all three shank flats to prevent slippage under load. Ensure the drilling machine is powered off and fully stopped before inserting or removing the bit. Use appropriate cutting fluid or coolant when drilling steel or cast iron to extend bit life and maintain hole tolerance. Follow applicable OSHA machine guarding requirements when operating drill presses or CNC equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 10.50 mm (0.4100 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.2400 inches (133.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.4300 inches (87.12 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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 with 3 Flats\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide and Gold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: CLE-LINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C74020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLE-LINE","offers":[{"title":"Default Title","offer_id":52103536542002,"sku":"C74020","price":21.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a63717d303a2ea6401b6692ea61bbb21_39a7985b-842b-4c21-af3a-80ebdb19dc41.jpg?v=1790071287","url":"https:\/\/voomisupply.com\/products\/cle-line-c74020-jobber-drill-bit-10-50mm-hss-split-point","provider":"Voomi Supply","version":"1.0","type":"link"}
