Built from M42 cobalt high-speed steel with an oxide coating, this bit handles tough materials including superalloys, stainless steel, and hardened workpieces where standard HSS bits fall short. The 135-degree split point reduces walking on contact and lowers thrust force needed to start a hole. At 2.25 inches overall length with a 0.75-inch flute, this is a standard jobber form factor sized for use in drill presses, hand drills, and CNC drilling operations. Licensed trades and industrial machinists rely on this series for consistent, repeatable hole quality in heavy-duty service.\u003c\/p\u003e\u003cp\u003eThe C15902 is rated for drilling superalloys and other difficult workpiece materials where heat resistance and edge retention are critical. The fast spiral flute evacuates chips efficiently in deep or interrupted cuts. The straight cylindrical shank fits standard drill chucks without modification. This bit is part of the Cleveland Series 3780, a heavy-duty cobalt line built to NAS specification and conforming to ASME B94.11M standards. It is sold individually with a minimum order quantity of 10 units, making it suitable for shop stocking and tool crib replenishment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for superior heat and wear resistance in superalloy drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and eliminates the need for a center punch on most surfaces\u003c\/li\u003e\n\u003cli\u003eOxide coating improves lubricity and extends tool life in high-heat cutting conditions\u003c\/li\u003e\n\u003cli\u003eFast spiral flute promotes aggressive chip evacuation during deep drilling\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design reduces cutting resistance and heat buildup at the tip\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B94.11M and NAS specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard shop consumable for any application requiring a 3\/32-inch cobalt jobber-length drill bit in a straight cylindrical shank configuration compatible with standard drill chucks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this drill bit requires seating the straight cylindrical shank fully and evenly in a keyed or keyless chuck before tightening. Machinists and fabricators should confirm the chuck capacity accommodates a 3\/32-inch shank diameter before use. Always ensure the workpiece is properly secured before drilling, and use an appropriate cutting fluid or coolant when drilling superalloys to manage heat and extend bit life. Inspect the cutting edges for wear or chipping between uses, as cobalt bits used beyond their service life can fracture under load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 3\/32 inch (0.0938 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Oxide\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\u003eFlute Type\u003c\/strong\u003e: Spiral (Fast)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3\/4 inch (0.750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/4 inches (2.250 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: 3\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloy\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: 3780\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M, NAS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: C15902\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51715690561842,"sku":"C15902","price":54.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02e10a3a26bea41aaf797649b8e4efcc_ac8425aa-f097-4c48-95f4-b998b8ebd81f.jpg?v=1788517280","url":"https:\/\/voomisupply.com\/products\/cleveland-c15902-cobalt-jobber-drill-bit-3-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
