Part of the Guhring Series 2464, it features a 118-degree faceted point, right-hand spiral flute, and web-thinned tip geometry. The overall length is 4.29 inches (109 mm), with a flute length of 2.72 inches (69 mm) and a straight-cylindrical shank diameter of 6.75 mm. Material grade K40 solid carbide and the FIREX coating combine to deliver heat resistance and edge retention, making this bit suited for high-production drilling in aluminum and other non-ferrous materials. It is installed by machinists and tool-and-die professionals in CNC and manual drill press operations.\u003c\/p\u003e\n\u003cp\u003eThe 9024640067500 is rated for use in aluminum and similar non-ferrous workpiece materials (Primary Workpiece Material Code N). The 5xD flute-to-diameter ratio supports controlled chip evacuation in moderate-depth holes. Maximum drilling depth is 2.318 inches (58.88 mm). The regular spiral geometry and two-flute design make it a practical general-purpose option for production shops, maintenance facilities, and precision machining environments where carbide tooling is standard. No coolant-through capability; external coolant or cutting fluid application is the appropriate method for heat management.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction, K40 material grade, for rigidity and wear resistance in non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003eFIREX coating provides thermal protection and extended tool life at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning reduces thrust force and improves centering accuracy\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral, two-flute design for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank (6.75 mm) fits standard drill chucks and collet systems without adapters\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN specification standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length carbide drill bit for use in standard drill chucks and collet holders accepting a 6.75 mm straight-cylindrical shank.

Secure the shank fully in the chuck or collet before operation and verify runout before drilling. Solid carbide tooling is brittle — avoid lateral loading, interrupted cuts without proper setup, or dropping the bit on hard surfaces. Apply external cutting fluid when drilling at sustained depths to manage heat, as this bit does not have coolant-through capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fraction)\u003c\/strong\u003e: 17\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.2656 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Grade K40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 4.29 inches (109 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.72 inches (69 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.318 inches (58.88 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.75 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 mm\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: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.012 to 0.000 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (Material Code N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2464\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 9024640067500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731266306354,"sku":"9024640067500","price":114.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3ca0e3fbda70d5451c9c0db247ff425_ad4ec06f-a508-41b6-8925-0e1d8c286de3.jpg?v=1788729003","url":"https:\/\/voomisupply.com\/products\/guhring-9024640067500-drill-bit-letter-h-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
