Built from M42 cobalt high-speed steel with an oxide coating, it delivers heat resistance and edge retention when drilling superalloys, stainless steel, and other hard or abrasive materials. The bit runs a 135-degree split point for self-centering entry with reduced thrust force, and features a fast-spiral flute geometry with a web-thinned, tapered web configuration. Overall length is 2.125 inches with a 0.750-inch flute length. Manufactured to ASME B94.11M standards and designated to NAS specification, this is a heavy-duty tool built for production and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis bit is sized to wire gauge 46, equivalent to 0.0810 inches decimal diameter. It is suited for drilling superalloys, high-nickel alloys, titanium, and similarly hard workpiece materials in aerospace, industrial maintenance, and precision fabrication applications. The straight-cylindrical shank fits standard drill chucks and collet systems without adapters. Right-hand cutting direction is compatible with conventional drill press, hand drill, and CNC spindle setups. It ships individually (package quantity of 1) and is subject to a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for superior heat and wear resistance in hard-material drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces walking and lowers required thrust force at entry\u003c\/li\u003e\n\u003cli\u003eOxide coating provides surface hardness and lubricity for extended tool life\u003c\/li\u003e\n\u003cli\u003eFast-spiral flute geometry improves chip evacuation in deep or interrupted cuts\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting resistance without sacrificing rigidity\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B94.11M and NAS specification designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks and collets accepting a 0.0810-inch straight-cylindrical shank. Primary workpiece material designation is superalloy; suitable for other hard and abrasive metals requiring cobalt-grade tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this bit should be performed by machinists or qualified trades personnel familiar with metalworking equipment. Secure the shank fully in the chuck and verify runout before drilling. Use appropriate cutting fluid or lubricant when drilling superalloys or stainless steel to reduce heat buildup and extend tool life. Do not exceed the rated speed range for the workpiece material and bit diameter; consult published SFM charts for cobalt HSS tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0810 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\u003eDrill Bit Finish\/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\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0810 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.375 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: -0.0005 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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003ePackage Weight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: C15897\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51718124503346,"sku":"C15897","price":57.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02e10a3a26bea41aaf797649b8e4efcc_4d7d1d88-e0d2-4c0e-824f-5bcacdb88896.jpg?v=1788550017","url":"https:\/\/voomisupply.com\/products\/cleveland-c15897-jobber-drill-bit-46-cobalt-m42","provider":"Voomi Supply","version":"1.0","type":"link"}
