Built from M42 cobalt steel, this bit delivers superior heat and wear resistance compared to standard high-speed steel tooling. The 135-degree split point starts on contact without a center punch and reduces walking on curved or irregular surfaces. With an overall length of 1-13\/16 inches and a parabolic flute geometry, the C14278 is engineered for short-reach, high-speed drilling in CNC machines, drill presses, and screw machine setups where rigidity and precision matter.\u003c\/p\u003e\n\u003cp\u003eThe C14278 is suited for drilling alloy steel and aluminum in manufacturing, fabrication, and maintenance environments. Its compact screw machine length reduces deflection and improves hole accuracy in tight-clearance applications. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. Machinists, tool and die technicians, and maintenance mechanics commonly use this bit size for tapping prep holes and precision-diameter through-holes in production settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction rated for heavy-duty drilling in alloy steel and aluminum\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirement\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile improves chip evacuation at higher feed rates\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces cutting resistance and heat buildup\u003c\/li\u003e\n  \u003cli\u003eScrew machine length at 1-13\/16 inches overall provides maximum rigidity and runout control\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of plus 0.0000 to minus 0.0005 inches for tight-tolerance hole requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for wire size 38 (0.1015 inches) screw machine length drill bits conforming to ASME B94.11M and ANSI specification designation.

Seat the straight-cylindrical shank fully in the chuck or collet and verify runout before resuming operations. Use appropriate cutting fluid or coolant when drilling alloy steel to extend tool life, noting that this bit does not feature through-coolant capability. Follow shop safety protocols and applicable OSHA machine-guarding requirements during all drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 38\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\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\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/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\u003eShank Diameter\u003c\/strong\u003e: 0.1015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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: plus 0.0000 to minus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eSeries\u003c\/strong\u003e: 2175\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: C14278\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693139329330,"sku":"C14278","price":16.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c7f0c56e8e931179bba92126b1a63d3.jpg?v=1788307840","url":"https:\/\/voomisupply.com\/products\/cleveland-c14278-screw-machine-drill-bit-wire-38-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
