Ground from solid carbide and finished with an AlTiN (aluminum titanium nitride) coating, it handles elevated cutting temperatures better than standard HSS tooling. The 140-degree notched point reduces thrust and self-centers on entry, minimizing walk on flat and curved surfaces. At 2.5 inches overall length with a 0.879-inch flute length, it fits standard drill chucks and CNC machining centers. This bit is suited for machinists, tool-and-die technicians, and metalworking professionals who need consistent, repeatable results in hardened or abrasive workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is sized at 5\/32 inch (0.1562 inch decimal) with a 3\/16-inch straight-cylindrical shank. It is used in ferrous and non-ferrous metalworking applications, including production machining, maintenance and repair operations, and fabrication shops. The regular spiral flute and web-thinned, parallel-web configuration promote chip evacuation and reduce cutting resistance. Maximum recommended drilling depth is 0.700 inch. Coolant-through capability is not supported on this bit, so external coolant or cutting fluid application is the standard practice when drilling deep features or hard alloys.\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\u003eAlTiN coating improves heat resistance and extends tool life at higher cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree notched point for reduced thrust and improved self-centering\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces cutting force and aids chip clearance\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 3\/16-inch shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance OEM-style jobber drill bit for use in manual drill presses, CNC machining centers, and hand-held power tools equipped with a chuck that accepts a 3\/16-inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist or metalworking technician familiar with proper feeds, speeds, and workholding practices. Secure the workpiece firmly before drilling to prevent movement and tool breakage. Carbide tooling is brittle and should not be subjected to interrupted cuts or side loading beyond what the tool geometry is rated for. Apply cutting fluid externally when drilling deep features or hard alloys to manage heat at the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 5\/32 inch (0.1562 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\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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.879 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\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\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\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: 63310312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748225745202,"sku":"63310312","price":77.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa7e8e316cb250b308473f8bfe1f3170.jpg?v=1788890648","url":"https:\/\/voomisupply.com\/products\/accupro-63310312-jobber-drill-bit-5-32-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
