Built from M42 cobalt high-speed steel, it delivers superior heat and wear resistance compared to standard HSS tooling. The 135-degree split point reduces thrust and eliminates the need for a center punch on most materials. With an overall length of 3-7\/16 inches and a straight cylindrical shank measuring 0.4375 inches in diameter, this bit fits standard drill chucks and CNC toolholding systems. The parabolic flute geometry promotes efficient chip evacuation in deeper holes.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for shop and field drilling operations where stub-length rigidity is preferred over jobber-length flexibility. The screw machine length profile reduces deflection in tight or confined setups, making it a common choice for drill press, turret lathe, and CNC machining center applications. Primary workpiece materials listed by the manufacturer include alloy steels and aluminum. The web-thinned, parallel web configuration helps maintain center cutting action throughout the tool life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction resists heat buildup during high-speed and interrupted cutting\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry thrust and self-centers without a pilot\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design improves chip flow and reduces chip packing\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web extends cutting efficiency as the bit wears and is resharpened\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank is compatible with standard and CNC chuck systems\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M standards with ANSI specification designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe C15074 is listed under Cleveland Series 2175A and is intended for drilling alloy steels and aluminum.

Secure workpieces firmly to prevent walking on entry, particularly in aluminum. Follow applicable shop safety standards and use appropriate cutting fluid for the workpiece material to extend tool life. Inspect the cutting edges before each use and regrind or replace when point geometry shows wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-3\/8 inches (1.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.4000 to 0.4500 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: 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: 0.9 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: C15074\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695728230706,"sku":"C15074","price":74.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3df712ae7837ba34c2aa39e0a778c1b_a0183c99-b438-4bda-a77d-135729369c99.jpg?v=1788337807","url":"https:\/\/voomisupply.com\/products\/cleveland-c15074-screw-machine-drill-bit-7-16-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
