Built from solid carbide with an AlTiN (aluminum titanium nitride) coating, it handles hardened steels, stainless, cast iron, and heat-resistant alloys where high-speed steel bits fall short. The 140-degree notched point reduces thrust and improves centering without a pilot hole. The straight-cylindrical shank measures 3\/8 inch in diameter, and overall length is 3 inches. Machinists and tool-and-die professionals install this bit in CNC machining centers, drill presses, and rigid setup hand machines where carbide rigidity and coating hardness are required.\u003c\/p\u003e\u003cp\u003eThis bit suits production and job-shop environments where surface footage and heat generation exceed the limits of coated HSS tooling. The spiral flute with regular helix and parallel web configuration supports chip evacuation in through-hole and blind-hole operations. Maximum recommended drilling depth is 1.5 inches, with a flute length of 1.8 inches. The 4xD flute-to-diameter ratio makes it a standard jobber geometry suitable for general-purpose deep drilling at this diameter. Web thinning reduces entry force and minimizes workpiece distortion at the start of cut.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance beyond HSS tooling\u003c\/li\u003e\n\u003cli\u003eAlTiN coating extends tool life in ferrous and heat-resistant alloy applications\u003c\/li\u003e\n\u003cli\u003e140-degree notched point for self-centering entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web configuration lowers cutting force at drill entry\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 3\/8-inch shank fits standard ER collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute promotes efficient chip evacuation in typical CNC and manual setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill bit compatible with any drill chuck or ER collet system accepting a 3\/8-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove this bit only after the spindle has come to a complete stop and the machine is locked out per shop lockout\/tagout procedures. Solid carbide is brittle — avoid side loading, interrupted cuts without proper fixturing, or over-cantilevered setups that induce vibration. Use manufacturer-recommended surface footage and feed rates for the workpiece material; running carbide too slowly in hard materials causes rubbing and premature edge failure. Coolant-through capability is not available on this bit, so direct external coolant or mist at the cutting zone when drilling materials that generate significant heat.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 3\/8 inch (0.3750 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\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\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: 63310064\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739265728818,"sku":"63310064","price":129.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd459ff9dab8e5a8a8f2751d75f676b5.jpg?v=1788812408","url":"https:\/\/voomisupply.com\/products\/accupro-63310064-jobber-drill-bit-3-8-in-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
