Ground to a 118-degree faceted point with web thinning, it cuts right-hand with a regular spiral flute and delivers consistent hole quality in aluminum and similar non-ferrous workpiece materials. At 3.74 inches overall length with a 1.85-inch flute and a maximum drilling depth of 1.194 inches, it fits standard straight-cylindrical chucks and collets. Diameter tolerance is held to +0.000 to -0.010 mm, making it suitable for applications where close hole sizing matters. Part of the GUHRING Series 2463, it conforms to DIN 6539 and is built to K40 carbide grade.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is sized at 7\/16 inch (0.4375 inches) diameter and is intended for use in CNC machining centers, drill presses, and screw machine setups where a shorter, stiffer stub-length tool reduces deflection. Its primary workpiece material rating is aluminum, though the K40 solid carbide construction and coated finish make it applicable across a range of general-purpose production drilling tasks. The 3xD flute-to-diameter ratio and web-thinned point reduce thrust and improve chip evacuation in shallow-to-moderate depth holes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide K40 grade construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eStub length (3.74 inches overall) minimizes deflection in tight setups\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.000 to -0.010 mm for close-tolerance holes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard chucks and collets without special toolholding\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6539 with Series 2463 designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement or direct-use solid carbide stub drill for general-purpose production drilling applications in aluminum and similar materials, compatible with any machine spindle or chuck accepting a straight-cylindrical shank at 11.11 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of carbide drill bits should be performed by qualified machinists familiar with speeds, feeds, and runout tolerances for carbide tooling. Ensure the spindle and chuck or collet are clean and within runout spec before seating the shank, as carbide is brittle and sensitive to side loading. Power down and lock out the machine before changing tooling. Coolant-through is not supported on this bit; external coolant or mist lubrication is recommended where applicable.\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\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.74 inches (95.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.85 inches (47.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.194 inches (30.34 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 11.11 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide, K40 Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.010 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6539\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2463\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.075 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9024630111100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51754713088306,"sku":"9024630111100","price":260.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb3bd143f28962c2d256fb85eb88b908_fda84a93-c3e4-4762-8214-b2401c91a8b1.jpg?v=1788948038","url":"https:\/\/voomisupply.com\/products\/guhring-9024630111100-carbide-stub-drill-bit-7-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
