At 0.0055 inches in diameter, this bit falls in the micro-range and is built for use in materials that demand dimensional accuracy and controlled entry geometry. The 120-degree drill point angle promotes centered starts and reduces walking on hard or thin substrates. With a 25.00 mm overall length and a 1.00 mm straight-cylindrical shank, it mounts cleanly in standard micro-drill chucks and collet systems. The bright, uncoated finish keeps the carbide surface consistent for applications where coating buildup or chemical interaction is a concern.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for precision machining operations including PCB drilling, watchmaking, medical device manufacturing, instrument fabrication, and other applications where sub-0.010-inch hole tolerances are required. The right-hand cutting direction and spiral flute geometry support clean chip evacuation at high spindle speeds typical in micro-drilling setups. It is installed and operated by machinists, tool-and-die makers, and precision fabricators using CNC or manual micro-drilling equipment. Coolant-through is not supported on this bit, so external or mist coolant should be used when the material and setup require it.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0055 inch diameter for micro and miniature hole applications\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003e120-degree point angle for accurate entry and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for applications sensitive to coating interaction\u003c\/li\u003e\n  \u003cli\u003eSpiral flute geometry supports chip evacuation at high RPM\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard micro-drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style micro drill bit in the Miniature Series, compatible with micro-drilling setups using a 1.00 mm straight-cylindrical shank chuck or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMicro drill bits at this diameter are extremely fragile and require a rigid, low-runout spindle to prevent breakage. Ensure the shank is fully seated and concentric in the collet before operation. Feed rates and spindle speeds should be dialed in for the specific workpiece material, as excessive feed force at this diameter will snap the bit. External or mist coolant is recommended when drilling heat-sensitive or abrasive materials, since this bit does not support coolant-through.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0055 inches\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\u003eOverall Length\u003c\/strong\u003e: 25.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.00 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\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\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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-6100014R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736843092274,"sku":"A-6100014R","price":258.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/674f4b0bde1ddb4ba06eae836a82701e_858d5575-5807-46c3-abd7-fb852c69fc22.jpg?v=1788780977","url":"https:\/\/voomisupply.com\/products\/accupro-a-6100014r-micro-drill-bit-0-0055-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
