It features a 2.80 mm (0.1102 inches) diameter and a 140-degree faceted point angle, which reduces thrust and improves centering on hard materials. The TiAlN coating provides thermal resistance and extended tool life at elevated cutting speeds. With an overall length of 66.00 mm and a flute length of 22.00 mm, this bit fits standard CNC machining centers and drill presses. It is intended for use by machinists and tool-and-die professionals working with ferrous and exotic alloys.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production and precision machining environments where tight tolerances and difficult workpiece materials are the norm. Primary workpiece materials include cast iron, stainless steel, and steel. Secondary applications cover aluminum and titanium alloys. The 5xD flute-to-diameter ratio and coolant-through design support deep hole drilling up to 18.60 mm, making it appropriate for mold work, aerospace component machining, and precision fabrication. The straight-cylindrical shank fits standard collets and drill chucks without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in material grade K40 for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating increases surface hardness and thermal stability at high spindle speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree faceted point with web thinning reduces entry thrust and improves hole accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and heat control during deep hole drilling\u003c\/li\u003e\n  \u003cli\u003e5xD flute ratio with maximum drilling depth of 18.60 mm for deeper bores relative to diameter\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 4.00 mm diameter with m7 tolerance for consistent tool holding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and precision drilling fixtures accepting a 4.00 mm straight-cylindrical shank.

Seat the straight shank fully in the collet or chuck and verify runout before starting a cut. Refer to the machine manufacturer and GUHRING cutting data guidelines for appropriate feed rates and spindle speeds; do not exceed the drill's rated maximum drilling depth of 18.60 mm per pass without retracting to clear chips. Coolant supply should be confirmed active before initiating a drilling cycle when using the through-coolant feature.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.80 mm (0.1102 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 22.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 18.60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\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: Straight-Cylindrical\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: K40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Aluminum, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6405\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 9064050028000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51740534866226,"sku":"9064050028000","price":207.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/adc38f6e3824ca57d816196474ffd4bd_9745527e-d88e-440e-8baa-1a9420ac725b.jpg?v=1788825758","url":"https:\/\/voomisupply.com\/products\/guhring-9064050028000-micro-drill-bit-2-80mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
