With a 1.45 mm (0.0571 inch) cutting diameter and a 120-degree point angle, this bit delivers clean, accurate entry in hard and abrasive materials where standard high-speed steel tooling falls short. The bright, uncoated finish suits a wide range of materials without altering dimensional tolerances. At 30 mm overall length with an 11.20 mm flute length, the compact geometry is built for controlled chip evacuation in shallow-to-moderate depth holes. Machinists and toolroom technicians working with precision components rely on solid carbide construction for rigidity and wear resistance at small diameters.\u003c\/p\u003e\u003cp\u003eThis bit is suited for use in CNC machining centers, drill presses, and precision benchtop machines where micro-diameter work is required. Typical applications include circuit board drilling, watch and instrument components, medical device parts, mold work, and other miniature fabrication tasks. The right-hand spiral flute promotes consistent chip removal during the cut. The straight-cylindrical shank at 1.50 mm diameter fits standard collet chucks used in high-speed spindles common to precision machining setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.45 mm cutting diameter with 0.0571 inch decimal equivalent for precise tool selection\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e120-degree standard point angle for accurate self-centering on entry\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute promotes effective chip evacuation\u003c\/li\u003e\n\u003cli\u003e1.50 mm straight-cylindrical shank fits standard collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style miniature drill bit for use in standard collet chucks and toolholders accepting a 1.50 mm straight-cylindrical shank, typical of CNC machining centers and precision drilling equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of micro drill bits should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully and evenly in the collet to prevent runout, which is especially critical at sub-2 mm diameters. Use appropriate spindle speeds and feed rates for the workpiece material and bit diameter; exceeding recommended parameters at this diameter will result in rapid tool failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1.45 mm (0.0571 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 30 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.25 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A-6100145R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738247823666,"sku":"A-6100145R","price":200.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fcb54a07b83e9fb011fd3f4691908400.jpg?v=1788797244","url":"https:\/\/voomisupply.com\/products\/accupro-a-6100145r-micro-drill-bit-1-45-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
