Built from M42 cobalt high-speed steel and coated with titanium nitride (TiN), this bit delivers extended cutting life in hard and abrasive materials. It features a 135-degree split point that reduces walking on contact and requires no center punch on most surfaces. The parabolic flute geometry improves chip evacuation during deep-hole drilling. At 5 inches overall length with a 3-5\/8-inch flute length, it fits standard jobber-length drill chucks without modification. Diameter tolerance is held to -0.0010 to 0.0000 inches for accurate hole sizing.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling ferrous metals, stainless steel, hardened alloys, and other difficult materials encountered in HVAC fabrication, plumbing rough-in, electrical panel work, and general mechanical assembly. The straight cylindrical shank accepts standard 3-jaw drill chucks on corded drills, drill presses, and magnetic base drills. The parabolic flute and web-thinned tip make it particularly effective when drilling sheet metal stacks, strut, angle iron, and structural members on the job site or in the shop. It conforms to ASME B94.11M and DIN 338 standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and increases surface hardness at the cutting edge\u003c\/li\u003e\n\u003cli\u003e135-degree split point starts on contact without center punching and reduces thrust load\u003c\/li\u003e\n\u003cli\u003eParabolic flute profile accelerates chip removal and reduces heat buildup in deep holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration improves cutting efficiency\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and DIN 338 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill bit with a 3\/8-inch straight cylindrical shank, compatible with any 3-jaw drill chuck rated for that shank diameter on corded drills, drill presses, and magnetic base drilling equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist, HVAC fabricator, or journeyman tradesperson should select the appropriate drill speed for the base material before use. Secure the workpiece fully before drilling to prevent rotation or slipping. When drilling steel or stainless, apply cutting fluid to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace or sharpen the bit if the split point shows visible wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches (127.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.38 inches (34.92 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\u003eMaterial\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill 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\u003eSeries\u003c\/strong\u003e: 2075T\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: 0.7 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: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C16687\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695706112306,"sku":"C16687","price":59.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72ec45573fd3d9ebc084e87d2026b024_6c411804-8211-4e02-8ee0-1376359c05f4.jpg?v=1788337607","url":"https:\/\/voomisupply.com\/products\/cleveland-c16687-3-8-inch-cobalt-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
