Built from M42 cobalt high-speed steel and finished with a gold oxide coating, this bit holds cutting-edge hardness at elevated temperatures better than standard HSS tooling. The 135-degree split point self-centers on contact, reducing the need for a center punch and minimizing walking on hard surfaces. A parabolic flute geometry promotes efficient chip evacuation during deep-hole drilling. This bit is suited for machinists, pipefitters, ironworkers, and maintenance mechanics who regularly cut through tough ferrous and non-ferrous metals.\u003c\/p\u003e\u003cp\u003eThe C16579 is intended for drilling cast iron, stainless steel, carbon steel, and non-ferrous metals in both shop and field environments. Its 5.5-inch overall length falls within standard jobber-length range, making it compatible with most drill chucks and magnetic drill setups. The straight cylindrical shank fits standard 3-jaw chucks without adapters. It meets ASME B94.11M and DIN 338 standards, confirming dimensional accuracy for production and maintenance drilling work where bit-to-bit consistency matters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\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 self-centers and reduces thrust force on entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute design improves chip flow and reduces heat buildup in deep holes\u003c\/li\u003e\n\u003cli\u003eGold oxide finish provides surface lubricity and additional corrosion resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting resistance without sacrificing rigidity\u003c\/li\u003e\n\u003cli\u003eCompliant with ASME B94.11M and DIN 338 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in cast iron, stainless steel, carbon steel, and non-ferrous metal workpieces.

Always wear appropriate eye protection and secure the workpiece before drilling. Use appropriate cutting fluid when drilling stainless steel or hardened steel to extend bit life and manage heat. Replace the bit if the cutting edge shows visible chipping, burning, or a marked increase in required feed force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2075\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/16 inches (0.4375 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\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches (139.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-1\/16 inches\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: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.44 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C16579\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51702100328754,"sku":"C16579","price":59.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1146823a33fda6388d23718d36172835.jpg?v=1788409158","url":"https:\/\/voomisupply.com\/products\/cleveland-c16579-cobalt-drill-bit-7-16-in-135-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
