It features a standard 118-degree split point with web thinning and a tapered web configuration, which reduces walking and lowers thrust on entry. The two-flute spiral design with regular helix promotes efficient chip evacuation during through-hole drilling. At 4.125 inches overall length with a 2.875-inch flute, this bit falls within the classic jobber-length envelope suited for hand-held and machine drilling alike. It is installed and used by machinists, maintenance technicians, HVAC fabricators, and general trade professionals working in metal, wood, and plastics.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for general-purpose drilling in a wide range of materials including mild steel, aluminum, cast iron, thermoplastics, and wood composites. The straight-cylindrical shank at 0.2660 inches diameter fits standard three-jaw drill chucks on portable drills, drill presses, and CNC turret machines. The Series 2002G classification places it within a family of general-purpose jobber bits intended for production and maintenance environments where repeatable hole quality at a consistent diameter tolerance of -0.0010 to 0.0000 inches is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter H size at 0.2660 inches decimal equivalent for consistent, measurable fitment\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning reduces entry thrust and minimizes walking\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles interrupted cuts and moderate heat buildup\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows visual inspection of wear and edge condition\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral geometry promotes clean chip evacuation in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 338 standards for jobber-length drill geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any standard three-jaw chuck accepting a 0.2660-inch straight-cylindrical shank, including portable drills, bench drill presses, and turret drilling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the chuck and verify runout before drilling. Power down the drill press or disconnect the tool from power before changing bits. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend edge life, even though this bit does not feature through-coolant capability. Follow shop safety protocols and applicable OSHA standards for rotating tool operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2660 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 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 Diameter\u003c\/strong\u003e: 0.2660 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\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: 2002G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, DIN 338\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: C72078\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51773303259442,"sku":"C72078","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/577905be93bec1ef2d0d0f86a384ebfa.jpg?v=1789162553","url":"https:\/\/voomisupply.com\/products\/cleveland-c72078-jobber-length-drill-bit-letter-h-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
