Built from M42 cobalt high-speed steel with an oxide coating, this bit handles superalloys, stainless steel, and other hard-to-machine workpieces where standard HSS bits fall short. Wire size 5 corresponds to 0.2055 inches in decimal, and the bit features a 135-degree split point for reduced thrust and self-centering entry without a pilot hole. The fast spiral flute promotes efficient chip evacuation in deep-hole applications. Licensed machinists, tool-and-die technicians, and industrial maintenance mechanics are the primary installers of this tooling.\u003c\/p\u003e\u003cp\u003eThe C15946 is suited for production drilling and job-shop work on superalloys, titanium, and hardened steels. The straight-cylindrical shank fits standard drill chucks on drill presses, CNC machining centers, and hand-held power tools. Its jobber-length geometry — 3.75 inches overall with a 1.25-inch flute length and 2.5-inch shank — fits bench drill presses and mill setups where rigid tool holding is available. It conforms to ASME B94.11M standards and carries a NAS specification designation, making it suitable for aerospace and defense production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for drilling superalloys, stainless, and hardened materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry thrust and eliminates the need for a center punch on most surfaces\u003c\/li\u003e\n\u003cli\u003eOxide coating provides lubricity and heat resistance during high-speed cutting\u003c\/li\u003e\n\u003cli\u003eFast spiral flute design accelerates chip evacuation in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration lowers cutting resistance and improves hole accuracy\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard 3-jaw drill chucks without an adapter\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and NAS specification standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit tooling replacement for Wire Size 5 (0.2055 inches) applications conforming to ASME B94.11M jobber-length standards; compatible with any drill press, machining center, or power drill accepting a straight-cylindrical shank of 0.2055 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists and maintenance technicians in drill presses, mills, or handheld power tools equipped with a keyed or keyless chuck rated for the shank diameter. Secure the shank fully in the chuck before operation and verify runout is within acceptable limits for the application. Always wear appropriate eye protection and follow applicable machine guarding requirements per OSHA 1910.212. Use cutting fluid or coolant appropriate for the workpiece material to maximize bit life when drilling superalloys or stainless steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2055 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt HSS\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\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\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2055 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\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\u003eStandards\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\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: C15946\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699856900402,"sku":"C15946","price":15.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02e10a3a26bea41aaf797649b8e4efcc_293e2c3e-db0a-42fd-a0eb-aa9b8f484609.jpg?v=1788382066","url":"https:\/\/voomisupply.com\/products\/cleveland-c15946-cobalt-jobber-drill-bit-wire-size-5","provider":"Voomi Supply","version":"1.0","type":"link"}
