It measures 0.0670 inches in diameter and 2 inches in overall length, with a 1-inch flute length and a straight-cylindrical shank. The 118-degree split point initiates contact quickly and reduces walking on entry. Two regular spiral flutes evacuate chips efficiently during through-hole operations. This is a heavy-duty grade bit built to NAS 907 Type A standards, suited for machinists, maintenance mechanics, and trade professionals drilling small-diameter holes in production or field environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for primary use in aluminum and is well suited to light-gauge metal fabrication, electrical enclosure work, HVAC equipment assembly, and general mechanical maintenance tasks requiring precise small-diameter holes. The web-thinned, tapered web design reduces thrust requirements, which is a practical advantage when working in tight quarters or with handheld equipment. The straight-cylindrical shank seats directly in standard drill chucks without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 51 wire gauge size — 0.0670 inches diameter for tight-tolerance small-hole work\u003c\/li\u003e\n  \u003cli\u003e118-degree split point reduces entry walking and lowers required thrust force\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with bright uncoated finish resists abrasion in aluminum and light metals\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web decreases cutting resistance on thin-stock and sheet material\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute geometry promotes consistent chip evacuation in short-hole drilling\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type A specification for heavy-duty grade tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3-jaw drill chucks accepting straight-cylindrical shanks at 0.0670 inches diameter.

Secure the straight-cylindrical shank firmly in the chuck to the full depth of the shank before operating. Use appropriate cutting fluid or lubrication when drilling aluminum to extend tool life and maintain hole tolerance. Inspect the cutting edges before each use and replace bits that show chipping, deformation, or diameter wear outside the stated tolerance of -0.0005 to 0.0000 inches.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0670 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\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 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\u003eStandard\u003c\/strong\u003e: NAS 907 Type A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2228\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: C73479\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51694569783602,"sku":"C73479","price":41.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f364efd6aec19afa2f91a820fcff892a_11b38fa0-2f8c-4844-b756-ce30d8ce93d3.jpg?v=1788325610","url":"https:\/\/voomisupply.com\/products\/cleveland-c73479-no-51-jobber-drill-bit-hss-118-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
