Built to Series 6400 specifications, it features a 1\/16 inch (1.59 mm) diameter with a TiAlN coating that extends tool life in high-heat, high-speed operations. The 140-degree faceted point angle provides accurate entry and reduces walking on hard surfaces. With a straight-cylindrical shank measuring 3.00 mm in diameter and an overall length of 47.00 mm, this bit mounts cleanly in standard collet-style holders used by machinists and toolroom professionals across production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is engineered for use in cast iron, stainless steel, and steel as primary workpiece materials, with secondary suitability for aluminum and titanium alloys. Its web-thinned geometry and spiral flute design support chip evacuation in shallow-to-moderate depth holes, with a maximum drilling depth of 7.70 mm. Typical applications include precision hole drilling in tight-tolerance components, fixture work, and production machining where a small-diameter carbide tool is required over a conventional HSS bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction rated at material grade K40 for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves thermal resistance and extends tool life in steel and stainless applications\u003c\/li\u003e\n  \u003cli\u003e140-degree faceted drill point for accurate entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned geometry aids chip clearance and reduces cutting torque at small diameters\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank (3.00 mm) for secure seating in collet chucks and drill chucks\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute, 4xD flute-to-diameter ratio, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series 6400 micro drill bit suitable for use in standard collet-style and drill-chuck toolholding systems accepting a 3.00 mm straight-cylindrical shank.

Before mounting, ensure the spindle and toolholder are clean and free of debris to prevent runout that can fracture carbide at this diameter. Set spindle speed and feed rate according to the workpiece material and machine capability — carbide micro drills are brittle and will break if deflected or side-loaded. Never use this bit in a hand drill or handheld rotary tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Inch)\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 1.59 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0626 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 47.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9.60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 7.70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 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\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\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\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\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: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Aluminum, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6400\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.013 pounds\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: 9064000015900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731651789106,"sku":"9064000015900","price":143.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b31a86e245eff3dda6618119805aba13_ef6cdf40-dfc6-4459-8d5c-c9822d4ec750.jpg?v=1788733577","url":"https:\/\/voomisupply.com\/products\/guhring-9064000015900-micro-drill-bit-1-16-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
