Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention that standard HSS bits cannot match. The 135-degree split point reduces walking and allows immediate cutting engagement without a center punch. At 4.625 inches overall length with a 2.875-inch parabolic flute, this stub-length geometry provides rigidity and reduced deflection in drill press and CNC applications. The straight cylindrical shank measures 0.6719 inches in diameter, matching the bit diameter for secure chuck retention. Machinists and fabricators reach for this bit when drilling alloy steel, aluminum, and other demanding workpiece materials.\u003c\/p\u003e\u003cp\u003eThe C14239 is suited for production machining, fabrication shops, and metalworking operations where shorter bit length means better stability and tighter hole tolerances. Its screw machine length profile fits standard drill presses, CNC machining centers, and production fixtures without extension. The parabolic flute geometry improves chip evacuation, which is especially useful when drilling deeper holes in aluminum or gummy alloys. Right-hand cutting direction is standard for all conventional drilling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for heat resistance and extended tool life in alloy and abrasive materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point for reduced thrust and self-centering entry without a center punch\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes fast chip evacuation and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web configuration lowers cutting forces on harder stock\u003c\/li\u003e\n\u003cli\u003eScrew machine length (stub) design maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M dimensional standards for consistent sizing and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or production bit for any drill press, CNC machining center, or handheld drill with a chuck capacity accepting a 0.6719-inch straight cylindrical shank.

Secure the shank fully in the chuck and confirm runout before starting a cut. Power down and de-energize the machine before changing bits or adjusting workpiece fixtures. Do not exceed the recommended feed and speed parameters for the workpiece material to avoid premature edge failure or bit breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 43\/64 inches (0.6719 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6719 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: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2175\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: C14239\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51723993055538,"sku":"C14239","price":104.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9ab5ef0e769097a233bee9eb65e19f3_1a5413b4-a44a-4523-a893-6401fabd131d.jpg?v=1788611204","url":"https:\/\/voomisupply.com\/products\/cleveland-c14239-cobalt-drill-bit-43-64-inch-135-point","provider":"Voomi Supply","version":"1.0","type":"link"}
