With a 1.55 mm (0.0610 inch) cutting diameter and a 140-degree point angle, it delivers accurate entry and clean hole geometry in tight tolerances. The spiral flute design promotes efficient chip evacuation during drilling. At 50 mm overall length with an 11 mm flute length and a 3.00 mm straight-cylindrical shank, this bit fits standard collet-style and chuck-based spindles. The bright, uncoated finish makes it suitable for applications where coating compatibility is a concern. This bit is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is used in precision machining, PCB drilling, instrument manufacturing, and other applications requiring small-diameter hole making. The miniature series designation indicates it is built for fine-tolerance work where standard drill bits are too large. Right-hand cutting direction suits conventional CNC machining centers, drill presses, and manual spindles configured for standard rotation. It is typically installed and operated by machinists, toolmakers, and precision fabricators working with metallic and non-metallic substrates where micro-scale accuracy is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.55 mm cutting diameter with 0.0610 inch decimal equivalent for cross-reference\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle for accurate entry and reduced walking\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in micro-diameter drilling\u003c\/li\u003e\n  \u003cli\u003eSpiral flute with regular helix promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003e3.00 mm straight-cylindrical shank fits standard collets and drill chucks\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for a broad range of work materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for precision drilling setups requiring a 3.00 mm straight-cylindrical shank and 1.55 mm cutting diameter in the miniature drill bit series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists or toolmakers familiar with micro-diameter tooling. Ensure the spindle and collet or chuck are clean and properly seated before securing the shank to prevent runout. At micro diameters, even minor misalignment or excessive feed rate can cause bit breakage. Power down the machine and confirm zero rotation before changing or inspecting the bit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.55 mm (0.0610 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11 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\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\/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\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A-6200155R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733368602930,"sku":"A-6200155R","price":328.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b4321bc42979ae7e58255a3cb560bd6.jpg?v=1788754775","url":"https:\/\/voomisupply.com\/products\/accupro-a-6200155r-micro-drill-bit-1-55-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
