It measures 5\/8 inch (0.6250 inches) in diameter with a 4-1\/4 inch overall length and a 2-3\/4 inch parabolic flute length. The 135-degree split point promotes accurate self-starting and reduces walking on entry. Manufactured from M42 cobalt high-speed steel, the bit carries a web-thinned, parallel web configuration that supports efficient chip evacuation. Right-hand cut geometry and a straight-cylindrical shank round out the design. This bit is appropriate for machinists, tool-and-die workers, and maintenance professionals who require reliable performance in tough materials.\u003c\/p\u003e\u003cp\u003eThe C15086 is suited for drilling alloy steel and aluminum in screw machine operations, short-hole drilling setups, and general metalworking applications where stub-length rigidity is preferred over jobber-length flex. The shorter body reduces deflection and improves positional accuracy in CNC machining centers, drill presses, and manual lathes. The parabolic flute geometry assists chip clearance during deeper passes in softer alloys. Applications span production machining shops, fabrication facilities, and maintenance departments working with structural alloy components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction resists heat buildup when drilling hard alloys and stainless-adjacent materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eParabolic flute profile promotes fast chip evacuation and reduces clogging\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web configuration lowers cutting resistance at the center\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length provides added rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets without adapters\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and ANSI specification designations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement or production drill bit for use in standard 5\/8-inch drill chucks, collet holders, and screw machine spindles; no specific model compatibility data was provided with this product.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance professionals familiar with drill press, lathe, or CNC tooling procedures. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Disconnect power to the machine and lock out the spindle before changing or inspecting tooling. Follow applicable OSHA machine guarding and PPE requirements when operating rotary cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/4 inches (4.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-3\/4 inches (2.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy, Aluminum\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 -0.0012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2175A\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: C15086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51703056924978,"sku":"C15086","price":131.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3df712ae7837ba34c2aa39e0a778c1b_1a541b29-877b-410a-9fca-a228b77ca1d0.jpg?v=1788414581","url":"https:\/\/voomisupply.com\/products\/cleveland-c15086-cobalt-screw-machine-drill-bit-5-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
