It features a 3.00 mm cutting diameter, a 140-degree cone relief point, and a multi-layer nano-Si proprietary coating that reduces friction and extends tool life under demanding cutting conditions. The bit runs right-hand cutting with a regular spiral flute configuration and is web-thinned to reduce thrust and improve chip evacuation. Coolant-through capability makes it well-suited for deep-hole applications where heat management is critical. Machinists and tooling specialists install this bit on CNC machining centers and drill presses in production environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for screw machine length applications where a short, rigid tool is needed to maintain positional accuracy at the spindle. Its 3xD flute-to-diameter ratio and straight cylindrical shank make it a direct fit for standard collet chucks and drill chucks used in high-volume metal cutting. Primary workpiece materials include steel and high-temperature alloys. The Series 8520 designation places it within a GUHRING line built for consistent performance on difficult-to-machine ferrous and exotic alloy workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction, Material Grade K40, for rigidity and wear resistance in hard metals\u003c\/li\u003e\n\u003cli\u003eMulti-layer nano-Si coating reduces heat buildup and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e140-degree cone relief point geometry improves self-centering and reduces walking on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned design lowers axial thrust and promotes cleaner chip formation\u003c\/li\u003e\n\u003cli\u003eCoolant-through channels support internal coolant delivery for deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eMeets DIN 6537 K standard for dimensional accuracy and tool geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit for use in CNC machining centers, drill presses, and automatic screw machines equipped with collet or drill chuck toolholding rated for a 6.00 mm straight cylindrical shank. Suited for steel and high-temperature alloy workpieces per Series 8520 application guidelines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician familiar with carbide tooling handling procedures. Solid carbide bits are brittle and must be handled carefully to avoid chipping the cutting edge before use. Secure the shank fully within the collet or chuck to the specified grip length before running the spindle. Verify coolant-through connections are properly engaged if internal coolant delivery is used, and confirm spindle speed and feed rates are appropriate for carbide tooling in the target material before cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.00 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 62.00 mm (2.4409 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 20.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 42.00 mm (1.6535 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 15.50 mm (0.6100 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003ePoint Type\u003c\/strong\u003e: Cone Relief\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Multi-layer nano-Si\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, High-Temp Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 8520\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537 K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.018 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: 9085200030000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51743068586290,"sku":"9085200030000","price":187.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b012925f4b2d2c88d3a961fb4c3b97ad_83054b42-6767-4068-8a7c-38d456c1adfb.jpg?v=1788842199","url":"https:\/\/voomisupply.com\/products\/guhring-9085200030000-screw-machine-drill-bit-3mm","provider":"Voomi Supply","version":"1.0","type":"link"}
