Built to Series 6400 standards, it features a 2.55 mm diameter, a 140-degree faceted point, and a TiAlN coating that extends tool life at elevated cutting temperatures. The spiral flute geometry and web-thinned, tapered web configuration promote clean chip evacuation and reduce entry thrust. The straight-cylindrical shank measures 4.00 mm in diameter, suiting standard collet and chuck tooling. This bit is sized for applications requiring tight tolerances, with a diameter tolerance of +0.002 to +0.012 mm.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is suited for production and maintenance machining environments where small-diameter, high-accuracy holes are required. Primary workpiece materials include cast iron, stainless steel, and steel. Secondary applications cover aluminum and titanium alloy. The 4xD flute-to-diameter ratio and 12.20 mm maximum drilling depth make it appropriate for shallow, precision holes in components such as hydraulic manifolds, valve bodies, instrumentation housings, and structural fabrications. A licensed machinist or toolroom technician is the typical end user.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide DK460UF grade construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides thermal protection and extended tool life in ferrous and stainless steel cutting\u003c\/li\u003e\n  \u003cli\u003e140-degree faceted point reduces walking and improves entry accuracy on hard substrates\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers thrust force and aids chip break at the drill tip\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard ER collets and drill chucks\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.002 to +0.012 mm supports close-tolerance hole requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide micro drill for use in CNC machining centers, drill presses, and manual toolroom equipment accepting a 4.00 mm straight-cylindrical shank.

Secure the shank fully in a balanced, runout-minimized collet or chuck before operation, as carbide micro drills are brittle and sensitive to side load and runout. This bit does not support coolant-through delivery; apply cutting fluid externally as required by workpiece material. Follow machine manufacturer feed and speed guidelines for carbide tooling at this diameter to prevent breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.55 mm (0.1004 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 59.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 15.30 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 12.20 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\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\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: 1 pound\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: 9064000025500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51735020077362,"sku":"9064000025500","price":147.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b31a86e245eff3dda6618119805aba13_8ff19ee9-a773-41a8-a238-4fb9d7ec34e7.jpg?v=1788769277","url":"https:\/\/voomisupply.com\/products\/guhring-9064000025500-micro-drill-bit-2-55mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
