It measures 13.00 mm (0.5100 inch) in diameter with an overall length of 5.9400 inches and a flute length of 3.9800 inches. The 135-degree split point self-centers on contact, reducing walking and the need for a center punch. A black oxide and gold coating improves lubricity and surface hardness. Built to Series 1878 standards and conforming to ASME B94.11M and DIN 338, this bit is suited for heavy-duty shop and field use by machinists, pipefitters, and general maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for right-hand rotation in standard drill presses, magnetic base drills, and handheld power drills. Primary workpiece materials are steel and cast iron, making it a practical choice for structural fabrication, pipe work, and equipment repair. The straight cylindrical shank with three flats accommodates most standard three-jaw chucks and quick-change systems. Maximum drilling depth is rated at 1.2800 inches, appropriate for through-hole and shallow blind-hole work in trade applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point self-centers and reduces thrust load on entry\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with black oxide and gold coating for improved wear resistance\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry promotes chip evacuation in ferrous materials\u003c\/li\u003e\n\u003cli\u003eTapered web configuration adds core strength for heavy-duty drilling\u003c\/li\u003e\n\u003cli\u003eStraight shank with three flats reduces slippage in chuck under load\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B94.11M and DIN 338 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber drill bit for standard three-jaw chucks and compatible quick-change systems accepting a 0.5100-inch straight shank, suitable for drill presses and handheld power drills used in steel and cast iron applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and maintenance technicians using standard drill press or handheld drilling equipment. Secure the shank fully in the chuck and confirm tightness before operation. Always wear appropriate eye protection and secure the workpiece before drilling. Reduce feed rate when breaking through the far side of the material to prevent grab and bit damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 13.00 mm (0.5100 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.9400 inches (150.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.9800 inches (101.09 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5100 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.9700 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.2800 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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 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\u003c\/strong\u003e: Black Oxide and Gold\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1878\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: CLE-LINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C74057\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLE-LINE","offers":[{"title":"Default Title","offer_id":51971149398322,"sku":"C74057","price":26.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a63717d303a2ea6401b6692ea61bbb21_6b775286-2cf6-4ad4-aa8c-525b9dc846a4.jpg?v=1789953598","url":"https:\/\/voomisupply.com\/products\/cle-line-c74057-jobber-drill-bit-13mm-hss-split-point","provider":"Voomi Supply","version":"1.0","type":"link"}
