Built to Series 3780 heavy-duty specifications, it carries an M42 cobalt steel construction with an oxide coating for heat and wear resistance. The 135-degree split point reduces walking and decreases the thrust required to start a hole without a center punch. A fast spiral flute geometry promotes efficient chip evacuation. This bit is sized at 7\/64 inches in diameter with a 2-5\/8-inch overall length, making it a standard jobber-length tool suited to drill presses, CNC machining centers, and hand-held power drills used in fabrication and maintenance work.\u003c\/p\u003e\n\u003cp\u003eThe C15909 is appropriate for professional metalworking applications where standard HSS bits fail prematurely. Its primary designation is superalloy drilling, but the M42 cobalt grade and oxide coating also perform well in stainless steel, hardened alloys, and cast iron. The straight-cylindrical shank accommodates standard three-jaw chucks. Right-hand cutting direction is standard for conventional drilling operations. This bit is sold individually and is intended for trade and industrial use where per-bit precision and durability are required across repeated operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction rated for heavy-duty drilling in superalloys and hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates walking on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eOxide coating improves heat resistance and extends tool life in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute design promotes rapid chip evacuation during deep drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting resistance at the tip\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M standards with NAS specification designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-grade replacement or direct-use drill bit compatible with any standard three-jaw chuck or collet system accepting a 7\/64-inch straight-cylindrical shank, including drill presses, hand drills, and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, toolmakers, and maintenance technicians using standard drill press or hand-held drilling equipment. Ensure the chuck is fully tightened and the workpiece is secured before operation. Use appropriate cutting fluid or coolant when drilling superalloys to manage heat buildup, as this bit does not support coolant-through delivery. Follow shop safety practices and applicable OSHA standards when operating rotary cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/64 inches (0.1094 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/64 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\u003eFlute Type\u003c\/strong\u003e: Spiral (Fast)\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\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Oxide\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eSeries\u003c\/strong\u003e: 3780\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: NAS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: C15909\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51715663429938,"sku":"C15909","price":58.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02e10a3a26bea41aaf797649b8e4efcc_3ba10264-cc35-4891-8dd7-0c9a78d05ac6.jpg?v=1788516940","url":"https:\/\/voomisupply.com\/products\/cleveland-c15909-cobalt-drill-bit-7-64-in-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
