It features a 135-degree split point for self-centering entry and reduced thrust, a right-hand spiral flute configuration, and a bright uncoated finish suited to non-ferrous chip evacuation. At 3.10 mm in diameter (0.1220 inches) with a 66.00 mm overall length (2.5984 inches), this drill fits standard CNC machining centers, drill presses, and handheld power tools accepting a 6 mm flatted shank. Licensed machinists and toolroom technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill is rated for aluminum and non-ferrous workpiece materials and is built to a 5xD flute-to-diameter ratio, yielding a 28.00 mm flute length (1.1024 inches) and a maximum recommended drilling depth of 23.00 mm. The 3-flat shank design prevents rotation in the chuck and allows consistent tool registration. Coolant-through capability supports high-cycle production environments where chip management and heat dissipation are critical. It suits precision fabrication, aerospace component work, and general metalworking applications where tight diameter tolerances are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and edge retention in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e135-degree point angle reduces walking and axial thrust at entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-cycle drilling with active chip and heat management\u003c\/li\u003e\n\u003cli\u003e3-flat shank prevents rotation and ensures repeatable tool seating\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish optimized for aluminum and non-ferrous chip adhesion resistance\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance held to 0.0002 to 0.0006 inches for consistent hole quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with toolholders and chucks accepting a 6 mm shank diameter.

Secure the 3-flat shank firmly in a compatible chuck or collet to rated clamping torque per the toolholder manufacturer specifications. Verify coolant-through passages are clear before use in high-cycle applications. Solid carbide tooling is brittle and should not be dropped or used to pry workpieces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.10 mm (0.1220 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (2.5984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm (1.1024 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 23.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.57 mm\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: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 3-Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0002 to 0.0006 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Specialized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03527 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5990785\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747630481714,"sku":"5990785","price":247.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c353ca9088e12bc5522946e4cf334e18.jpg?v=1788883763","url":"https:\/\/voomisupply.com\/products\/kennametal-5990785-solid-carbide-jobber-drill-3-10-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
