Built from M42 cobalt high-speed steel and finished with a gold oxide coating, this bit delivers heat resistance and edge retention when working through tough materials. The 135-degree split point starts on contact without a center punch, reducing walking and thrust. The parabolic flute geometry clears chips efficiently, making it well-suited for deep-hole drilling in production environments. Two right-hand flutes and a straight cylindrical shank ensure compatibility with standard drill chucks. This bit meets ASME B94.11M and DIN 338 standards and carries a heavy-duty grade rating.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use on cast iron, non-ferrous metals, stainless steel, and carbon steel. It fits applications where standard HSS bits fail prematurely due to heat buildup or work hardening, such as drilling stainless steel fittings, cast iron flanges, or structural steel in HVAC, plumbing, and electrical rough-in work. The 29\/64 inch diameter is a common size for bolt clearance and anchor hole preparation. A licensed electrician, pipefitter, or HVAC installer performing metal fabrication or penetration work would typically use this bit with a heavy-duty corded drill or drill press.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction resists heat and maintains edge integrity in hard and abrasive metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point eliminates walking and reduces required thrust at drill startup\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design promotes efficient chip evacuation in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating reduces friction and provides light corrosion resistance during storage\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web configuration lowers cutting resistance and improves hole entry\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 338 standards for jobber-length drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber-length drill bit for use in standard three-jaw drill chucks and drill press spindles accepting a 29\/64 inch straight cylindrical shank.

Ensure the workpiece is securely clamped before beginning the cut. Apply cutting fluid when drilling stainless steel or cast iron to extend bit life and prevent work hardening at the cut surface. Do not exceed the recommended speed range for the workpiece material, and allow the flutes to clear chips freely to avoid 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: 29\/64 inch (0.4531 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 29\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4400 inch\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 (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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inch\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\u003eSeries\u003c\/strong\u003e: 2075\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 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: C16580\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51709134111026,"sku":"C16580","price":65.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3f58d5ae5e4d7c73d755b21cb3e3a79.jpg?v=1788451769","url":"https:\/\/voomisupply.com\/products\/cleveland-c16580-cobalt-drill-bit-29-64-inch-135-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
