Built from M42 cobalt high-speed steel, it handles alloy steels, aluminum, and other tough workpiece materials that standard HSS bits struggle with. The 135-degree split point starts on contact without a center punch and reduces thrust. Overall length is 2-3\/16 inches with a straight-cylindrical shank at 0.1730 inches in diameter. The parabolic flute profile clears chips efficiently, making this bit a practical choice for close-tolerance screw machine and drill press work.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are shorter and more rigid than jobber-length bits, which reduces deflection in turret lathes, screw machines, and short-setup drill press applications. This bit is suited for residential and commercial fabrication shops, maintenance departments, and mechanical contractors drilling into alloy steel and aluminum components. The Series 2175A designation places it in a consistent product line for procurement and replacement tracking. Right-hand cut orientation follows standard drilling conventions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction resists heat buildup when drilling hard alloys\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces walk and lowers required thrust at entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes rapid chip evacuation in deep holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web reduces cutting resistance through the full flute length\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides added rigidity versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance held to +0.0000 to -0.0007 inches per ASME B94.11M\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit for use in standard straight-shank drill chucks, turret lathes, and CNC screw machine setups accepting a 0.1730-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and maintenance technicians using standard drill chuck equipment. Secure the shank fully in the chuck and verify runout before cutting. Use appropriate cutting fluid for the workpiece material to extend bit life and maintain hole tolerance. Inspect the cutting edges before each use and replace if chipping or heat discoloration is present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 17\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1730 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eOverall Length\u003c\/strong\u003e: 2-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/8 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: 0.1730 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-1\/16 inches (1.0625 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: C15107\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51694583447858,"sku":"C15107","price":28.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3df712ae7837ba34c2aa39e0a778c1b_528f5763-5ace-4e1b-8beb-93394ff142bd.jpg?v=1788325804","url":"https:\/\/voomisupply.com\/products\/cleveland-c15107-screw-machine-drill-bit-no-17-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
