Built to ASME B94.11M standards, this left-hand-cut bit features a 135-degree split point that reduces walking and requires no center punch on most surfaces. The gold finish provides a visual indicator of heat treatment and adds a layer of surface protection. At 4.125 inches overall length with a 2.375-inch flute, it fits standard drill chucks and is sized for work where compact length and rigidity matter more than deep-hole clearance.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for metal fabrication, aerospace maintenance, and general machining applications where high-cobalt tooling is specified. The left-hand cutting direction is particularly useful when extracting damaged or broken right-hand fasteners, as the rotation of the bit tends to back out the fastener as it cuts. Machinists, tool-and-die workers, and MRO technicians working with superalloy and titanium components will find this bit appropriate for their setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material withstands the high heat generated when drilling superalloys and titanium\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates the need for a center punch on many materials\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting direction aids in backing out broken or seized right-hand fasteners\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction reduces cutting resistance and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eGold finish provides visual confirmation of cobalt heat treatment\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M dimensional standards for mechanics-length drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8-inch straight-cylindrical shank drill chucks.

Always verify spindle speed against recommended surface footage for cobalt tooling in the target material before cutting. Use cutting fluid or coolant appropriate for the workpiece material to extend tool life, even though this bit does not have through-coolant capability. Secure the workpiece firmly before drilling to prevent movement that can chip the split point or break the bit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 3\/8 inches (0.3750 inches \/ 9.53 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 Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\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: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 inches (104.78 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Gold\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: 1880\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Mechanics\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloy, Titanium\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: 0.18 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: C30524\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLE-LINE","offers":[{"title":"Default Title","offer_id":51977631203634,"sku":"C30524","price":130.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b134b4adfba4606bea2beda61ef850a7.jpg?v=1789979663","url":"https:\/\/voomisupply.com\/products\/cle-line-c30524-cobalt-mechanics-drill-bit-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
