Ground from M42 cobalt high-speed steel, this bit runs at a 135-degree split point angle with a parabolic flute geometry for fast chip evacuation and reduced thrust. The gold oxide coating provides added surface hardness and lubricity. At 31\/64 inch (0.4844 inch) in diameter with a 5-7\/8 inch overall length, it is sized for demanding work where standard high-speed steel bits wear prematurely. Machinists, maintenance mechanics, and fabricators reach for this bit when drilling through tough materials in production or field service environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for drilling cast iron, stainless steel, carbon steel, and non-ferrous metals. The parabolic flute profile clears chips efficiently in deep-hole drilling without packing the flutes. The straight-cylindrical shank seats securely in standard three-jaw chucks and most drill press or hand-drill setups. It is a practical choice wherever high-speed steel bits fail prematurely due to heat buildup or abrasive workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for extended tool life in hard and abrasive metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers required thrust at the start of the cut\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design promotes fast, continuous chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eGold oxide finish adds surface hardness and reduces friction during cutting\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration for improved cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 338 standards for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard three-jaw chucks accepting a 31\/64 inch straight-cylindrical shank.

Secure the shank fully and verify chuck tightness before operation. Use appropriate cutting fluid or coolant on stainless steel and cast iron to manage heat, even though this bit does not support through-coolant. Inspect the cutting edges for wear or chipping before each use and replace when the split point geometry is no longer intact.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 31\/64 inch (0.4844 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 31\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5000 inch (38.10 mm)\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: M42 Cobalt High-Speed Steel\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSpecification Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 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: C16582\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51714423849266,"sku":"C16582","price":74.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56f3ed8df9b9594733057ebce087e3d3.jpg?v=1788501253","url":"https:\/\/voomisupply.com\/products\/cleveland-c16582-cobalt-jobber-drill-bit-31-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
