It carries an AlTiN (Aluminum Titanium Nitride) coating that extends tool life in elevated-temperature cutting conditions. The 140-degree notched point geometry reduces thrust and improves self-centering on entry. At 5 inches overall length with a 2.671-inch flute length, this bit suits standard jobber-length drilling applications. A web-thinned, parallel-web construction reduces cutting resistance. This bit is used by machinists and tool-and-die tradespeople in production drilling on CNC machining centers and manual drill presses.\u003c\/p\u003e\n\u003cp\u003eThe 63309918 is suited for drilling steel alloys, stainless steel, cast iron, and other hard materials where high-speed steel tooling falls short. The right-hand spiral flute design handles standard right-hand spindle rotation. The straight-cylindrical shank measures 3\/4 inch in diameter, fitting standard drill chucks and collet holders at that size. Maximum rated drilling depth is 2.43 inches. The 4xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes. This bit is a production-grade tool intended for professional machine shop and industrial manufacturing environments.\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-material drilling\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides heat resistance and extended tool life at higher cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree notched point reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web lowers cutting resistance and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 3\/4 inch diameter fits standard chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand regular spiral flute for efficient chip evacuation in through and blind holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style production drill bit for use in CNC machining centers and manual drill presses equipped with a 3\/4-inch straight-shank chuck or collet holder.

Ensure the spindle and workholding are fully secured before initiating the cut. Because this is a solid carbide tool, avoid interrupted cuts or side-loading that can cause chipping or fracture. Refer to the cutting tool manufacturer speed-and-feed recommendations for the specific workpiece material before use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 21\/32 inches (0.6562 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.671 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.43 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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: 0.12 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: 63309918\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754140795186,"sku":"63309918","price":336.61,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e371e11a4add2a0cc81ac93ed30979b1.jpg?v=1788943589","url":"https:\/\/voomisupply.com\/products\/accupro-63309918-carbide-drill-bit-21-32-inch-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
