It measures 3\/16 inch (0.1875 inch decimal) in diameter with a 2-7\/8 inch overall length and a 1-1\/2 inch flute length. The 135-degree split point geometry reduces walking on contact and lowers thrust force, which matters when drilling into tough workpiece materials in tight setups. The left-hand cutting direction is a deliberate design feature, commonly used when paired with a reverse-direction drill to help back out broken fasteners while drilling. Machinists, maintenance mechanics, and tool-and-die professionals are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis bit fits mechanics-length drilling applications where a shorter overall length provides better rigidity than a jobber-length bit. It is suited for use in drill presses, CNC drilling setups, and hand drills operating in reverse. Primary workpiece materials are superalloys and titanium, though it performs across a broad range of metals. The gold coating provides a visual indicator of the cobalt substrate and offers light oxidation resistance during cutting. The tapered web configuration and web-thinned geometry reduce cutting resistance as the bit progresses into the material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for drilling superalloys, titanium, and hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces bit walking and lowers required thrust force\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting direction aids in backing out broken or seized fasteners\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eGold coating provides visual cobalt identification and light oxidation resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M standard for twist drill dimensions and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style mechanics-length drill bit compatible with standard straight-cylindrical shank drill chucks.

Secure the workpiece firmly before drilling to prevent rotation or movement. Use appropriate cutting fluid for the workpiece material to extend bit life and maintain cut quality. Do not exceed the recommended spindle speed range for cobalt bits cutting titanium or superalloy to avoid premature edge breakdown.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch \/ 4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/8 inches (2.8750 inches \/ 73.03 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 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 Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Gold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloy, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1880\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: CLE-LINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C30512\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLE-LINE","offers":[{"title":"Default Title","offer_id":52085898412338,"sku":"C30512","price":113.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3a660fdc8c1cd9d10a6993b41940e857.jpg?v=1790059285","url":"https:\/\/voomisupply.com\/products\/cle-line-c30512-cobalt-mechanics-drill-bit-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
