It features a 1.64 mm diameter with a 120-degree point angle and a spiral flute geometry that promotes efficient chip evacuation during cutting. The straight-cylindrical shank measures 2.00 mm in diameter, allowing it to seat securely in standard collet chucks and micro drill holders. At 38.00 mm overall length with a 7.20 mm flute length, this bit is built for miniature-series work where dimensional accuracy and tool rigidity are critical. The bright, uncoated finish is suitable for use across a range of materials without the added thermal considerations of coated tooling.\u003c\/p\u003e\u003cp\u003eThis bit is suited for machining, toolmaking, electronics fabrication, and precision manufacturing environments where small-diameter hole generation is required. Right-hand cutting direction and regular spiral geometry make it compatible with conventional CNC machining centers, drill presses, and hand-operated precision drilling equipment. It is commonly specified in job shops, prototype facilities, and production lines that require repeatable micro-hole performance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.64 mm drill diameter (0.0646 inch decimal equivalent) for micro-scale precision work\u003c\/li\u003e\n\u003cli\u003e120-degree point angle for accurate entry and reduced walking on hard surfaces\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance in demanding applications\u003c\/li\u003e\n\u003cli\u003eSpiral flute design promotes chip evacuation and reduces heat buildup during drilling\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating delamination risk in sensitive material applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 2.00 mm diameter for secure collet or chuck retention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style miniature-series drill bit compatible with standard collet chucks and micro drill holders that accept a 2.00 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with micro-diameter drill bit handling. Ensure spindle runout is minimized before use, as excessive runout accelerates breakage in small-diameter carbide tooling. Secure the shank fully within the collet or chuck to the recommended grip depth before operation. Avoid side-loading or manual flexing of the bit during or outside of operation.\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\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\u003eOverall Length\u003c\/strong\u003e: 38.00 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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-6120164R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729526784306,"sku":"A-6120164R","price":244.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f21dba1819f553d812e76f41f5e9e9dd.jpg?v=1788705728","url":"https:\/\/voomisupply.com\/products\/accupro-a-6120164r-micro-drill-bit-1-64-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
