Built from solid carbide grade K40 and finished with a FIREX coating, this bit delivers consistent cutting performance in production and maintenance environments. It features a 118-degree faceted point angle and a web-thinned tip geometry that reduces entry force and improves chip evacuation. The 4 mm diameter and straight-cylindrical shank suit standard drill chucks and collet holders. Machinists, toolroom technicians, and maintenance mechanics are the typical end users for this style of bit.\u003c\/p\u003e\u003cp\u003eThis drill bit is configured for right-hand cut with a regular spiral flute pattern rated at a 5xD flute-to-diameter ratio. It is suited for general-purpose drilling operations in aluminum and other non-ferrous materials classified under material code N. Typical applications include production machining, fixture fabrication, and precision maintenance drilling where a solid carbide bit is required for tool life and dimensional accuracy. The straight-cylindrical shank allows direct mounting in standard chucks without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide K40 grade substrate for hardness and wear resistance in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eFIREX coating reduces friction and extends tool life compared to uncoated carbide\u003c\/li\u003e\n\u003cli\u003eWeb-thinned 118-degree faceted point reduces thrust force and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design promotes efficient chip evacuation at typical feed rates\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eConforms to DIN specification for consistent dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length carbide drill bit for use in CNC machining centers, drill presses, and hand-held drilling equipment accepting a 4 mm straight-cylindrical shank.

Secure the shank fully within the collet or chuck to the manufacturer-recommended insertion depth before tightening. Verify runout with an indicator before production use, as carbide bits are sensitive to lateral load from misalignment. Follow applicable shop safety procedures and machine manufacturer guidelines when setting feed rates and spindle speeds for carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75 mm (2.95 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 43 mm (1.69 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 37 mm (1.457 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 32 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\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\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eSpecification\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2464\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 9024640040000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51738571342130,"sku":"9024640040000","price":50.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3ca0e3fbda70d5451c9c0db247ff425_55d2508e-a1e1-49f3-8abc-aa636b8479fd.jpg?v=1788801142","url":"https:\/\/voomisupply.com\/products\/guhring-9024640040000-jobber-drill-bit-4mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
