Built to Series 2133 specifications and conforming to ASME B94.11M and DIN 1897 standards, it features a 135-degree split point for fast, accurate starts with minimal walking. The web-thinned, parallel-web construction reduces thrust force and improves chip evacuation. At 3.25 inches overall length with a 1.875-inch flute and a straight cylindrical shank, this is a heavy-duty tool suited for production drilling environments where rigidity and tool life matter.\u003c\/p\u003e\n\u003cp\u003eThis bit is engineered for drilling alloy steel and aluminum in screw machine and short-hole drilling applications. The M42 cobalt material grade gives it the heat resistance needed when drilling harder metals at higher feed rates or with limited coolant. Its compact screw machine length provides added rigidity compared to jobber-length bits, making it a practical choice for CNC lathes, turret lathes, drill presses, and automatic screw machine setups where reach is limited and hole quality is critical. Right-hand cut with a regular spiral and two flutes for standard chip clearance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter W size at 0.3860 inches with a diameter tolerance of +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003eM42 cobalt construction handles elevated cutting temperatures in alloy steel and aluminum\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning for reduced thrust and self-centering starts\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (3.25 inches OAL) provides greater rigidity than jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank at 0.3860 inches diameter fits standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B94.11M and DIN 1897 specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cutting tool for drill presses, CNC lathes, turret lathes, and automatic screw machines accepting a 0.3860-inch straight cylindrical shank.

Secure the shank fully in a properly sized chuck or collet before operation and verify runout is within acceptable limits. Do not exceed the machine's rated spindle speed for the workpiece material and bit diameter. No coolant-through capability is present on this bit, so apply cutting fluid externally when drilling alloy steels to extend tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3860 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned, Parallel Web\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 (34.92 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3860 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2133\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 1897 (ANSI, DIN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\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: C14707\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699880886578,"sku":"C14707","price":28.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cafea86f11d3670f1ca79187a969174c.jpg?v=1788382510","url":"https:\/\/voomisupply.com\/products\/cleveland-c14707-letter-w-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
