Built from M42 cobalt high-speed steel with a gold oxide coating, this bit handles tough workpiece materials that wear out standard HSS tooling. The 135-degree split point reduces walking and lowers feed pressure at the start of the cut. The parabolic flute geometry improves chip evacuation, which is critical when drilling deep holes in dense alloys. Overall length is 5.945 inches with a straight-cylindrical shank diameter of 0.4921 inches. This is a heavy-duty grade tool intended for production and maintenance drilling in trade and industrial environments.\u003c\/p\u003e\n\u003cp\u003eThe C16611 is sized at 12.5 mm (0.4921 inches decimal) and is suited for drilling cast iron, stainless steel, carbon steel, and non-ferrous metals. Typical applications include fabrication shops, pipefitters and plumbers sizing holes through structural steel and plate, HVAC sheet metal and structural work, and general MRO maintenance tasks. The web-thinned, tapered web design reduces torque requirements and extends cutting life in harder materials. Two flutes provide chip clearance across a 3.9764-inch flute length.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walk and lowers required thrust force\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design accelerates chip removal in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating provides lubricity and heat resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces torque and breakage risk\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard three-jaw drill chucks without adapters\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 standard drill chucks accepting a 0.4921-inch straight-cylindrical shank, conforming to ASME B94.11M and DIN 338 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a drill press, magnetic drill, or hand drill with a chuck rated for the shank diameter before applying power. Secure the workpiece firmly to prevent movement during the cut. Use appropriate cutting fluid when drilling stainless steel or cast iron to manage heat and extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or dulling is evident to avoid workpiece damage or bit breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 12.5 mm (0.4921 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.945 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.9764 inches (101 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.97 inches (50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4921 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel, Grade M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2075\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.3 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C16611\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693219971378,"sku":"C16611","price":76.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e5c5f3ef72ce91f3407fbab0f1888ec_f266972d-6cf5-40c6-9711-49221206a06d.jpg?v=1788309175","url":"https:\/\/voomisupply.com\/products\/cleveland-c16611-cobalt-jobber-drill-bit-12-5-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
