It is designed for general-purpose drilling in aluminum and other non-ferrous materials, operating at high cutting speeds where carbide grade K40 and the FIREX coating provide thermal and wear resistance. The straight-cylindrical shank seats securely in standard drill chucks. Two spiral flutes in a regular helix evacuate chips efficiently, and the web-thinned point reduces thrust and improves centering on entry. Installers and machinists in production and maintenance environments reach for this bit when tolerance and tool life matter.\u003c\/p\u003e\u003cp\u003eThis bit fits drilling applications in light-metal fabrication, HVAC sheet-metal work, and general mechanical assembly where a Letter J diameter is required. The 5xD flute-to-diameter ratio and 2.720-inch flute length support moderate-depth through-holes without pecking cycles in most setups. It is catalogued under Guhring Series 2464 and conforms to DIN specification standards, making it a direct match for shops sourcing to metric DIN tool standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide K40 grade body with FIREX coating for extended wear life in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point with web thinning reduces entry thrust and improves hole location accuracy\u003c\/li\u003e\n\u003cli\u003eTwo regular-helix spiral flutes, 2.720 inches long, for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 7.03 mm diameter fits standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eMaximum drilling depth of 2.302 inches (58.46 mm) within a 4.290-inch overall length\u003c\/li\u003e\n\u003cli\u003eDIN specification designation — suitable for shops with metric tool-standard requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any standard drill chuck or collet accepting a 7.03 mm straight-cylindrical shank.

Carbide bits are brittle — avoid lateral loading, interrupted cuts without proper feed support, and hard impacts that can chip the cutting edge. Confirm chuck or collet runout is within acceptable limits before use, as excessive runout accelerates edge wear and reduces hole tolerance. Power down and lock out the machine spindle completely before changing or inspecting the bit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: Letter J (0.2770 inches)\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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 4.290 inches (109.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.720 inches (69.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.302 inches (58.46 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7.03 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2464\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.075 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: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9024640070300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51749976178994,"sku":"9024640070300","price":116.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3ca0e3fbda70d5451c9c0db247ff425_2338ba4d-112d-4747-93b1-60ef1eceb1b4.jpg?v=1788912844","url":"https:\/\/voomisupply.com\/products\/guhring-9024640070300-drill-bit-letter-j-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
