Built to Series 3780 standards and classified as heavy duty, it features a 135-degree split point that reduces walking on entry and lowers thrust force compared to a conventional 118-degree grind. The M42 cobalt high-speed steel construction provides heat and wear resistance needed when drilling stainless steel, Inconel, titanium, and similar tough materials. A fast spiral flute geometry promotes chip evacuation, and the oxide finish adds surface hardness. This bit is used by machinists, pipefitters, and HVAC fabricators working with high-strength metals on the job site or in the shop.\u003c\/p\u003e\u003cp\u003eThe C15944 fits standard drill chucks and is suited for hand-held and machine-mounted drilling operations where a 13\/64-inch diameter hole is required. Its straight-cylindrical shank seats securely in keyed or keyless chucks. The 3-5\/8-inch overall length and 1-3\/16-inch flute length make it appropriate for shallow-to-moderate depth holes in superalloy components, structural steel, and other hard metals encountered in HVAC, plumbing, and general fabrication work. The web-thinned, tapered web design reduces cutting resistance without sacrificing rigidity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for high heat resistance in hard and abrasive metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walk and entry thrust on tough workpieces\u003c\/li\u003e\n\u003cli\u003eFast spiral flute promotes efficient chip evacuation during drilling\u003c\/li\u003e\n\u003cli\u003eOxide coating adds surface hardness and mild corrosion resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers cutting resistance and extends bit life\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard keyed and keyless chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling superalloys, stainless steel, and other hard metals.

Secure the workpiece firmly before drilling to prevent movement. This bit is intended for use by qualified machinists, pipefitters, or trade professionals familiar with proper drilling techniques and speeds for the workpiece material. Follow the drill press or power tool manufacturer guidelines for RPM settings appropriate to the material and bit diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 13\/64 inches (0.2031 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 13\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2-7\/16 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 HSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 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, 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: C15944\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51698460492082,"sku":"C15944","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02e10a3a26bea41aaf797649b8e4efcc_f9ab959f-a9d0-4963-b499-297f89b4537b.jpg?v=1788363206","url":"https:\/\/voomisupply.com\/products\/cleveland-c15944-cobalt-drill-bit-13-64-in-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
