Built from solid carbide grade K40, it features a FIREX coating that extends tool life by reducing heat buildup and surface friction at the cutting zone. The 118-degree faceted point with web thinning promotes accurate entry and reduces thrust force on the workpiece. At 5.94 inches overall length with a 3.98-inch spiral flute, this bit delivers consistent chip evacuation in a standard jobber profile. Machinists and toolroom technicians working on CNC machining centers and drill presses will find this bit sized for direct collet or chuck mounting.\u003c\/p\u003e\u003cp\u003eThe 9024640120000 is designed for general-purpose drilling in aluminum and similar non-ferrous workpiece materials, identified under primary workpiece material code N. The 12 mm diameter with a straight-cylindrical shank seats into standard 12 mm collets or three-jaw chucks without adapters. A flute-to-diameter ratio of 5xD and a maximum drilling depth of 3.27 inches (83 mm) make it appropriate for through-hole and moderate-depth blind-hole applications in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide K40 grade construction for rigidity and wear resistance in non-ferrous cutting\u003c\/li\u003e\n\u003cli\u003eFIREX coating reduces friction and extends tool life compared to uncoated carbide\u003c\/li\u003e\n\u003cli\u003e118-degree faceted drill point with web thinning for clean entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard collets and chucks directly\u003c\/li\u003e\n\u003cli\u003eDIN specification designation ensures dimensional conformance to recognized standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-standard replacement or direct-use jobber drill bit for 12 mm straight-cylindrical collet chucks and drill press chucks on CNC machining centers, knee mills, and drill presses.

Ensure the collet or chuck bore is clean and free of chips before inserting the shank to maintain runout tolerances. Refer to the machine manufacturer guidelines and applicable shop safety procedures when setting feed rates and spindle speeds for carbide tooling in aluminum applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 12 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 151 mm (5.94 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 101 mm (3.98 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 83 mm (3.27 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 50 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.012 to 0.000 mm\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 Designation\u003c\/strong\u003e: DIN\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: 9024640120000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51749145477426,"sku":"9024640120000","price":339.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3ca0e3fbda70d5451c9c0db247ff425_02eeeb1e-daf0-4fd9-9e57-fa9e3c7963a1.jpg?v=1788902595","url":"https:\/\/voomisupply.com\/products\/guhring-9024640120000-jobber-drill-bit-12mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
