Built from solid carbide and finished with an AlTiN (Aluminum Titanium Nitride) coating, this bit delivers extended tool life and heat resistance when cutting hard or abrasive materials. It measures 27\/64 inch (0.4219 inch) in diameter with a 4-inch overall length and features a 140-degree notched point for accurate self-centering entry. The straight-cylindrical shank at 7\/16 inch diameter seats securely in standard drill chucks. This bit is intended for use by machinists, tool-and-die professionals, and skilled tradespeople working with CNC equipment or manual drill presses.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production drilling in metals including hardened steels, stainless steel, cast iron, and high-temperature alloys where standard HSS tooling falls short. The spiral flute geometry with a regular spiral type and a 4xD flute-by-diameter ratio promotes efficient chip evacuation during through-hole and blind-hole operations. The flute length is 1.941 inches, with a maximum recommended drilling depth of 1.690 inches. It is appropriate for both manual and CNC drilling setups in job shop, maintenance, and fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides oxidation resistance and extends tool life at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003e140-degree notched point improves self-centering and reduces thrust force at entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web configuration reduces cutting resistance and improves chip flow\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 7\/16 inch shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for conventional drilling operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length replacement or production drill bit for use in standard drill chucks and collet holders accepting a 7\/16 inch straight shank, compatible with CNC machining centers, drill presses, and hand-held drilling equipment configured for solid carbide tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit should be installed and operated by qualified machinists or tradespeople familiar with carbide tooling requirements. Ensure the drill chuck or collet is clean and properly tightened before operation, as carbide is brittle and sensitive to runout. Coolant-through is not supported on this bit, so external coolant or cutting fluid application is recommended when drilling ferrous metals. Follow the machine manufacturer and tooling supplier guidelines for appropriate spindle speeds and feed rates for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 27\/64 inch (0.4219 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.941 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.690 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\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\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 63309967\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51976919253298,"sku":"63309967","price":170.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3acf0f1ff80e83b3e20b72c4e2292bf9.jpg?v=1789979171","url":"https:\/\/voomisupply.com\/products\/accupro-63309967-jobber-drill-bit-27-64-in-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
