Built from M42 cobalt high-speed steel with an oxide coating, it runs cooler and resists wear under heavy-duty cutting conditions. The 135-degree split point reduces walking and thrust at entry, making it well suited for production drilling without a center punch. Overall length is 3-1\/8 inches with a 1-inch spiral flute length. The straight cylindrical shank measures 0.1520 inches in diameter, matching the wire gauge size 24 decimal equivalent of 0.1520 inches.\u003c\/p\u003e\u003cp\u003eThis bit is intended for metal fabrication shops, aerospace maintenance, and industrial service work where hole tolerance and tool life matter. The fast spiral flute promotes chip evacuation in deep or interrupted cuts. The tapered web and web-thinned geometry reduce cutting force, which is critical when drilling nickel-based superalloys, titanium, or stainless steel. It is sold individually and fits standard drill chucks accepting straight cylindrical shanks in the 0.1520-inch range. Licensed machinists, tool-and-die workers, and maintenance technicians working to ASME B94.11M standards will find the Series 3780 geometry appropriate for precision hole work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for heat and wear resistance in superalloy drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and eliminates walking on entry\u003c\/li\u003e\n\u003cli\u003eOxide coating provides lubricity and additional surface hardness\u003c\/li\u003e\n\u003cli\u003eFast spiral flute with tapered, web-thinned geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of -0.0007 to 0.0000 inches for consistent, close-tolerance holes\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and NAS specification designations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber-length drill bit suitable for use in standard drill presses, CNC machining centers, and hand-held power drills equipped with chucks accepting 0.1520-inch straight cylindrical shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this bit requires a clean, properly sized drill chuck; inspect chuck jaws for wear before seating the shank. Always power down and lock out the drilling machine before changing bits. Use appropriate cutting fluid or coolant when drilling superalloys or stainless steel to extend tool life, noting this bit does not support coolant-through delivery. Verify workpiece is firmly clamped per shop safety standards before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1520 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt HSS (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 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: 0.1520 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Finish\/Coating\u003c\/strong\u003e: Oxide\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\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\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: C15923\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699471581490,"sku":"C15923","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02e10a3a26bea41aaf797649b8e4efcc_51f8faa5-56df-4ebd-80c9-26efb41e490a.jpg?v=1788376113","url":"https:\/\/voomisupply.com\/products\/cleveland-c15923-jobber-length-drill-bit-wire-24-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
