Built from cobalt M42 high-speed steel, it handles the heat and wear demands of drilling alloy steels and aluminum without losing edge integrity. The 135-degree split point reduces thrust and self-centers on contact, eliminating the need for a center punch in most applications. Parabolic flutes evacuate chips efficiently, and the web-thinned, parallel-web configuration keeps cutting resistance low. Overall length is 3.25 inches, making it compact and rigid for short-hole work in production or field environments.\u003c\/p\u003e\u003cp\u003eThis bit fits production drilling, maintenance, and fabrication applications where a stub-length drill is preferred for rigidity and accuracy. Screw machine length drills are standard in CNC drill presses, turret lathes, and bench drill setups where reduced overhang minimizes deflection. Primary workpiece materials include alloy steel and aluminum, making this a solid choice for mechanical contractors, millwrights, and machinists handling structural or component fabrication tasks. Right-hand cut with a straight-cylindrical shank, it seats directly in standard drill chucks and collet holders without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt M42 construction for heat resistance and extended tool life in alloy and aluminum drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point self-centers and reduces entry thrust\u003c\/li\u003e\n\u003cli\u003eParabolic flutes with web thinning for fast chip evacuation and low cutting resistance\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides maximum rigidity and minimal deflection\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M standards with ANSI specification designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-production screw machine length drill bit suitable for use in drill presses, CNC machining centers, turret lathes, and hand-held drill setups accepting a 0.3770-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with cutting tool safety. Secure the shank fully in the chuck or collet and verify runout before engaging the workpiece. Always use appropriate cutting fluid when drilling alloy steel to reduce heat buildup and extend tool life. Inspect the cutting edges before each use and do not operate a chipped or dull bit, as this increases the risk of bit failure and workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3770 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3770 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, 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 Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\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\u003eSeries\u003c\/strong\u003e: 2175A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ANSI\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: C15151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699836846386,"sku":"C15151","price":66.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3df712ae7837ba34c2aa39e0a778c1b_f0ceb8a6-413c-464c-9a1d-4dca6ce0b224.jpg?v=1788381842","url":"https:\/\/voomisupply.com\/products\/cleveland-c15151-screw-machine-drill-bit-letter-v-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
