It carries a TiAlN (titanium aluminum nitride) coating that increases surface hardness and thermal resistance, extending tool life in harder workpiece materials. The 130-degree four-facet point geometry reduces thrust force and improves centering accuracy at entry. With an overall length of 50 mm (approximately 1.97 inches) and a 3 mm (approximately 0.118 inches) shank diameter, this bit is sized for use in CNC machining centers, drill presses, and high-speed spindles. It is part of the OSG Series 5330 and is suited for machinists, toolroom technicians, and precision fabricators.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in precision machining environments where small-diameter holes are required in materials such as hardened steels, stainless steel, cast iron, and high-temperature alloys. The TiAlN coating performs well in dry and semi-dry cutting conditions, making it a practical choice for shops running production cycles without flood coolant on small-diameter work. The 14 mm (approximately 0.551 inches) flute length accommodates moderate hole depths typical in micro-drilling operations. Right-hand cut geometry is standard for conventional spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves thermal resistance and extends tool life in dry or semi-dry cutting\u003c\/li\u003e\n  \u003cli\u003e130-degree four-facet point reduces walking and lowers entry thrust force\u003c\/li\u003e\n  \u003cli\u003e2.5 mm (0.0984 inches) cutting diameter with a 3 mm shank for secure chuck or collet grip\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, compatible with standard CNC and manual spindle rotation\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through channels — suited for external coolant or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a precision micro drill bit for use in CNC machining centers, drill presses, and high-speed spindles accepting a 3 mm shank diameter. Suitable for drilling hardened and abrasion-resistant materials where a TiAlN-coated solid carbide tool is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool should be installed by a qualified machinist or toolroom technician familiar with small-diameter carbide tooling. Ensure the spindle and collet or chuck are clean and true before seating the shank, as runout will cause premature breakage in micro-diameter drills. Carbide is brittle — avoid side-loading or manual prying. Set feed rates and spindle speeds according to the workpiece material and the tool manufacturer guidelines for 2.5 mm solid carbide; do not use feed or speed values from high-speed steel drill charts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.5 mm (0.0984 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3 mm (0.118 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50 mm (1.97 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 14 mm (0.551 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Four Facet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3300250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51750992281906,"sku":"3300250","price":60.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7adcbc9e59b9737ab1b31f6a4f6c800d_4f564651-27f6-4083-8853-c35bfd1c646e.jpg?v=1788921023","url":"https:\/\/voomisupply.com\/products\/osg-3300250-micro-drill-bit-2-5mm-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
