Built to the 2175A series specification, it features a 3\/8 inch diameter, a 135-degree split point for self-centering starts, and a parabolic flute geometry that promotes efficient chip evacuation. The overall length measures 3-1\/8 inches with a 1-13\/16 inch flute length, making it well suited for close-clearance and drill-press work. Machinists, tool-and-die technicians, and maintenance mechanics rely on this bit when drilling alloy steels and aluminum alloys that demand more heat resistance than standard high-speed steel provides.\u003c\/p\u003e\u003cp\u003eThis bit is intended for screw machine, drill press, and CNC drilling operations in both shop and field environments. Its stub-length profile reduces deflection in shallow-hole applications and in situations where minimal tool stick-out is required. Primary workpiece materials include alloy steels and aluminum. The right-hand cut, straight-cylindrical shank fits standard three-jaw chucks and collets sized for 3\/8 inch tooling without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt material grade provides elevated heat and wear resistance for hard-metal drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust force and eliminates the need for a center punch on most metals\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry improves chip flow and reduces clogging in deep cuts\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel-web construction maintains core strength while lowering cutting resistance\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length minimizes deflection and improves hole-location accuracy\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M standards with a diameter tolerance of +0.0000 to -0.0010 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit screw machine length drill bit for use with standard 3\/8 inch straight-cylindrical chuck and collet tooling on drill presses, lathes, and CNC machining centers.

Secure the shank fully in a properly rated chuck or collet before operation and confirm the spindle is at a complete stop before changing bits. Always use appropriate cutting fluid or coolant for the workpiece material, even though this bit does not include through-coolant capability. Follow applicable shop safety standards and machine guarding requirements when operating drilling equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2175A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 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\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 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\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: C15070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51720327528754,"sku":"C15070","price":58.47,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3df712ae7837ba34c2aa39e0a778c1b_3dfaf52d-1893-4f17-9e37-0797acf32f37.jpg?v=1788562496","url":"https:\/\/voomisupply.com\/products\/cleveland-c15070-screw-machine-drill-bit-3-8-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
