At 1.65 mm (0.0650 inches) in diameter, this bit features a 140-degree faceted point angle and a TiAlN (titanium aluminum nitride) coating that extends tool life in high-temperature cutting environments. The straight-cylindrical shank measures 3.00 mm and fits standard precision collet chucks. With an overall length of 52.00 mm and a flute length of 14.90 mm, this drill is built for controlled, accurate entry in tight-tolerance work. It is suited for use by machinists and tool-room technicians working with CNC machining centers, drill presses, and precision fixtures.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is optimized for primary workpiece materials including cast iron, stainless steel, and steel (ISO material codes K, M, and P). Secondary applications include aluminum and titanium alloys (ISO codes N and S). The 7xD flute-to-diameter ratio supports deeper drilling relative to diameter, and the web-thinned, tapered web configuration reduces thrust force at entry. Maximum recommended drilling depth is 12.90 mm. This tool is intended for production and job-shop environments where small-diameter, high-precision holes are required across a range of metal workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction from GUHRING material grade DK460UF for rigidity and wear resistance in micro-diameter tooling\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves heat resistance and extends tool life in ferrous and difficult-to-machine materials\u003c\/li\u003e\n  \u003cli\u003e140-degree faceted point angle reduces walking and improves entry accuracy on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web lowers thrust force and reduces the risk of drill deflection at small diameters\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.002 to +0.012 mm supports tight-tolerance hole requirements\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction with regular spiral flutes for standard chip evacuation in through and blind holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eListed under GUHRING Series 6400 and 6401.

Ensure the spindle and collet are clean and properly torqued before seating the shank to prevent runout at small diameters. Coolant-through is not supported on this drill; external coolant or minimum quantity lubrication (MQL) should be applied per shop practice. Do not exceed the recommended maximum drilling depth of 12.90 mm without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.65 mm (0.0650 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 52.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 14.90 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 12.90 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: DK460UF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.002 to +0.012 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 7xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel (ISO K, M, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Aluminum, Titanium Alloy (ISO N, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6400, 6401\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 9064010016500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51733298217266,"sku":"9064010016500","price":154.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/489d9af55ee688e15482278f4b8bb7d6.jpg?v=1788753761","url":"https:\/\/voomisupply.com\/products\/guhring-9064010016500-micro-drill-bit-1-65mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
