The 135-degree split point geometry reduces walking at entry and lowers the thrust required to start the cut, making it well suited for production drilling in alloy steels and aluminum. The web-thinned, parallel-web configuration keeps the cutting edge aggressive through the full depth of the hole. At 3.25 inches overall length, this stub-style bit fits standard drill chucks without requiring extended reach setups. The straight-cylindrical shank measures 0.3860 inches in diameter with a 1.375-inch shank length, giving solid grip in both keyed and keyless chucks. This bit is manufactured to ASME B94.11M and meets NAS 907 Type C specification.\u003c\/p\u003e\n\u003cp\u003eScrew machine length drill bits are a standard choice in production machining, job-shop environments, and maintenance repair operations where rigidity and accuracy matter more than depth reach. The C70301 is appropriate for hand-held drill use, drill press work, and CNC setups requiring a compact, high-stiffness bit. Primary workpiece materials include alloy steel and aluminum. The shorter flute length of 1.875 inches limits deflection in interrupted cuts and thin-wall applications. This bit is sold individually and is suitable for machinists, millwrights, and industrial maintenance technicians working in metal fabrication or general manufacturing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter W size — 0.3860 inches decimal equivalent, tolerance +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry walking and lowers drilling thrust\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty high-speed steel construction for alloy steel and aluminum applications\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel-web design maintains cutting efficiency at full depth\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length — 3.25 inches OAL — maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and NAS 907 Type C specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production-supply drill bit for applications in alloy steel and aluminum workpieces requiring a Letter W, screw machine length drill with a straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the straight-cylindrical shank firmly in a keyed or keyless chuck before use. Ensure the drill press or handheld drill is powered off and triggers are locked out before changing or inspecting the bit. Use appropriate cutting fluid for alloy steel applications to extend tool life and maintain hole tolerance. Inspect the split point for wear or chipping between uses, as a damaged point will increase entry deflection and degrade hole quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: Letter W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDecimal Inch Size\u003c\/strong\u003e: 0.3860 inches\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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches (82.55 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.375 inches\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: 0.3860 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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 Material\u003c\/strong\u003e: Alloy Steel, Aluminum\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: 2330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, NAS 907 Type C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: C70301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51689724641586,"sku":"C70301","price":19.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65d59c5d84d088f5fd5069571a2a0a7a_13b6a80c-dd6a-4e8c-a273-5cbf64fbe04e.jpg?v=1788263499","url":"https:\/\/voomisupply.com\/products\/cleveland-c70301-drill-bit-letter-w-0-386-in-hss-135-pt","provider":"Voomi Supply","version":"1.0","type":"link"}
