With a cutting diameter of 1.86 mm (0.0732 inches) and a 120-degree drill point angle, this bit delivers clean, accurate entry points in hard and abrasive materials where standard high-speed steel tooling falls short. The bright uncoated finish maintains sharp cutting edges right out of the package. An overall length of 38.00 mm (1.496 inches) and a 2.00 mm straight-cylindrical shank make it compatible with standard collet and chuck setups used in CNC drilling, precision machining, and circuit board fabrication.\u003c\/p\u003e\n\u003cp\u003eThis bit belongs to the Miniature Series and is suited for production and repair work requiring consistent hole quality at small diameters. Typical applications include printed circuit board drilling, instrument component machining, medical device manufacturing, and precision metalworking in aluminum, brass, stainless steel, and similar materials. The right-hand cutting direction and spiral flute geometry support efficient chip evacuation during through-hole drilling operations. Sold individually, with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.86 mm (0.0732 inches) cutting diameter 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 drill point angle for accurate, self-centering entry\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish maintains consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eSpiral flute with right-hand cut promotes efficient chip removal\u003c\/li\u003e\n  \u003cli\u003e2.00 mm straight-cylindrical shank fits standard collets and chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a miniature series solid carbide micro drill bit compatible with CNC machining centers, drill presses, and hand-held precision drilling equipment fitted with collets or chucks accommodating a 2.00 mm straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with micro-diameter drill bit handling. Ensure the spindle and workpiece are fully secured before starting the cut, as micro drill bits are susceptible to breakage under lateral load or runout. Power down all equipment before changing tooling. Avoid applying excessive feed pressure on entry, as carbide micro drills require controlled feed rates to prevent fracture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.86 mm (0.0732 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\u003eOverall Length\u003c\/strong\u003e: 38.00 mm (1.496 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8.40 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\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\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  \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-6120186R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729487626546,"sku":"A-6120186R","price":270.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86706a67c64c26038ed21e3368f511b0_097ce6a1-ab06-4d0c-8bc7-de0e76b34dcd.jpg?v=1788705186","url":"https:\/\/voomisupply.com\/products\/accupro-a-6120186r-micro-drill-bit-1-86mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
