It carries a 1.64 mm diameter, a 140-degree split point, and a titanium aluminum nitride (TiAlN) coating that extends tool life by reducing heat buildup and improving wear resistance at the cutting edge. At 42 mm overall length with a 3.00 mm shank diameter and 10 mm flute length, it is sized for use in CNC machining centers, drill presses, and precision hand-held spindles. Right-hand cutting geometry suits standard spindle rotation. This bit is used by machinists, toolmakers, and precision fabricators working in metals, composites, and hard plastics.\u003c\/p\u003e\u003cp\u003eThe 3300164 is suited for micro-hole drilling operations in production and job-shop environments. The 140-degree point geometry reduces thrust force and walking at entry, making it well-adapted to work on hardened steel, stainless steel, cast iron, aluminum alloys, and similar materials. The TiAlN coating performs well in dry or minimal-lubrication cutting conditions. It belongs to OSG Series 5330, which targets small-diameter, high-performance drilling requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.64 mm cutting diameter with 0.0646 inch decimal equivalent\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle reduces entry thrust and bit walk\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves heat resistance and extends tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and accuracy at micro diameters\u003c\/li\u003e\n\u003cli\u003eRight-hand cut geometry for standard CNC and drill press spindle rotation\u003c\/li\u003e\n\u003cli\u003e3.00 mm shank diameter fits common collet and chuck toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use micro drill bit for applications requiring a 3.00 mm shank and 1.64 mm cutting diameter, typical of CNC machining centers and precision drilling setups using standard collet systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or toolroom personnel familiar with small-diameter carbide tooling. Ensure the spindle and toolholder are clean and properly torqued before seating the shank. Carbide micro drills are brittle — avoid side loading, interrupted cuts without proper feed rate adjustment, and re-chucking with debris in the collet. Confirm spindle RPM and feed rate are appropriate for the workpiece material and 1.64 mm diameter before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.64 mm (0.0646 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003eOverall Length\u003c\/strong\u003e: 42 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10 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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.055 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 3300164\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731518783794,"sku":"3300164","price":67.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7adcbc9e59b9737ab1b31f6a4f6c800d_2f216bf0-5493-4fbc-999b-79c32cf60331.jpg?v=1788732058","url":"https:\/\/voomisupply.com\/products\/osg-3300164-micro-drill-bit-1-64mm-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
