Built from M42 cobalt high-speed steel, this bit handles alloy steels and aluminum without breaking down under heat. It carries a 135-degree split point angle with web thinning for self-centering and reduced thrust on entry. The parabolic flute design evacuates chips efficiently, keeping the cut clean. Overall length is 2-3\/16 inches with a straight-cylindrical shank diameter of 0.1730 inches, making it compatible with standard drill chucks and quick-change holders. This bit is manufactured to ASME B94.11M and ANSI specification standards, giving machinists and fabricators a verifiable quality benchmark.\u003c\/p\u003e\u003cp\u003eThe C15307 is suited for screw machine operations, turret lathes, CNC machining centers, and bench drilling setups where short, rigid tooling is required. Wire size 17, with a decimal equivalent of 0.1730 inches, is a common callout in precision hole work for fastener clearance, tapping prep, and close-tolerance bores. The 135-degree split point performs well on aluminum and alloy workpieces where a standard 118-degree point tends to walk. Right-hand cutting direction is standard for conventional drill press and CNC spindle rotation. This bit is sold individually but requires a minimum order quantity of 10 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat resistance in alloy and aluminum drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces thrust and self-centers on entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute profile improves chip evacuation and extends tool life in deep-hole applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 0.1730 inches fits standard chucks without adapters\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web configuration reduces cutting resistance\u003c\/li\u003e\n\u003cli\u003eManufactured to ASME B94.11M and ANSI specification standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production drill bit for use in screw machine, CNC, and bench drilling setups requiring wire size 17 (0.1730 inches) diameter tooling in the 2175N series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of drill bits should be performed by a machinist or qualified tradesperson with the spindle fully stopped and the machine powered down or locked out per OSHA lockout\/tagout procedures. Secure the straight-cylindrical shank fully within the chuck jaws to the maximum grip depth before tightening. Inspect the cutting edges and split point for chips or wear before each use. Do not exceed the recommended speed and feed rates for the workpiece material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 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\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: 0.1730 inches\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 Length\u003c\/strong\u003e: 1-1\/16 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 -0.0007 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy, Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2175N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, ANSI\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: C15307\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51700647395634,"sku":"C15307","price":183.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2309869b92ee0af058849d85c603124f_cac51134-6558-4e18-b3d1-7c1a22ff2188.jpg?v=1788393271","url":"https:\/\/voomisupply.com\/products\/cleveland-c15307-cobalt-screw-machine-drill-bit-17","provider":"Voomi Supply","version":"1.0","type":"link"}
