It measures 7 mm (0.2756 inches) in diameter with an overall length of 3.54 inches and a flute length of 1.65 inches. The 150-degree point angle reduces thrust and improves self-centering on entry, making it well suited for harder workpiece materials. The bright uncoated finish allows direct visual inspection of the carbide substrate. Three spiral flutes with a regular helix provide efficient chip evacuation and stable cutting geometry at the 5xD flute-to-diameter ratio. The straight cylindrical shank seats cleanly in standard drill chucks. Licensed trades and machinists working with tight-tolerance applications will recognize the ANSI specification designation as confirmation of dimensional conformance.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for right-hand cutting in stationary drilling equipment such as drill presses, CNC machining centers, and high-speed hand drills where carbide rigidity can be fully utilized. It falls within the 0.25 to 0.30 inch (7 mm to 8 mm) diameter range, making it a common size for tapping pilot holes, through-holes in ferrous and non-ferrous metals, and close-tolerance work in composites or hard plastics. The single-piece solid carbide construction is preferred in production environments where consistent hole quality across repeated cuts is required. It is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003e150-degree point angle reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eThree spiral flutes with regular helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — substrate condition visible at inspection\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eANSI specification designation confirms dimensional compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard jobber-length drill bit for use in drill presses, CNC machining centers, and hand drills accepting a straight cylindrical shank within the 7 mm to 8 mm diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSolid carbide drill bits are brittle and must be secured in a properly tightened chuck before operation — side loads or angled entry can cause breakage. Power down and de-energize the machine before bit changes. Carbide is not recommended for use in hand-held drilling where deflection cannot be controlled. Follow applicable OSHA machine guarding requirements and the tool manufacturer's recommended spindle speed and feed rate for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7 mm (0.2756 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.54 inches (90 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.65 inches (42 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 150 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10391\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732475085106,"sku":"10391","price":112.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87382a22041b3c3918b736ac8dde38b2.jpg?v=1788743291","url":"https:\/\/voomisupply.com\/products\/accupro-10391-solid-carbide-jobber-drill-bit-7-mm-150-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
