It measures 1.72 mm in diameter (0.0677 inches) with a 38 mm overall length and a 7.20 mm flute length. The 120-degree point angle promotes accurate entry and reduces walking on hard or brittle materials. The bright, uncoated finish suits applications where coating buildup would be a concern. This bit belongs to the Miniature series and is typically installed by machinists, toolmakers, and precision fabricators working with tight tolerances in metalworking or circuit board drilling operations.\u003c\/p\u003e\u003cp\u003eThis micro drill bit is suited for precision drilling in small-diameter through-holes and blind holes in ferrous and non-ferrous materials. The straight-cylindrical shank with a 2.00 mm diameter fits standard collet chucks and micro drill chucks used in CNC machining centers, benchtop drill presses, and hand-held precision drilling fixtures. Its regular spiral flute geometry supports controlled chip evacuation in shallow-depth applications. No coolant-through capability is present, so external coolant or dry cutting methods apply depending on material requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.72 mm cutting diameter (0.0677 inches) for tight-tolerance micro drilling\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e120-degree standard point angle for accurate positioning and reduced deflection\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for non-ferrous metals and non-metallic materials\u003c\/li\u003e\n\u003cli\u003eSpiral flute, right-hand cut geometry for standard rotational drilling setups\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 2.00 mm shank for compatibility with common collet and chuck systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard collet chucks and micro drill chucks accepting a 2.00 mm straight-cylindrical shank, as used in CNC machining centers and precision bench drilling equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and toolroom technicians. Secure the shank firmly in a collet or drill chuck before operation and verify runout with a dial indicator when tolerances are critical. Do not exceed the recommended spindle speed for the material and diameter being drilled. Because this bit has no coolant-through capability, apply external coolant or cutting fluid as appropriate for the workpiece material to prevent heat buildup and premature wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.72 mm (0.0677 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 2.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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: Miniature\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-6120172R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731403243826,"sku":"A-6120172R","price":270.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74bc7919f7bfe82a19ae707d67147dbc.jpg?v=1788730581","url":"https:\/\/voomisupply.com\/products\/accupro-a-6120172r-micro-drill-bit-1-72-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
