With a 0.0283-inch cutting diameter and a 120-degree drill point angle, it delivers clean, accurate entry in hard and abrasive materials where standard high-speed steel bits fall short. The bright, uncoated finish keeps the surface true without added coating thickness — critical at this diameter. The straight-cylindrical shank and spiral flute geometry promote consistent chip evacuation in miniature-scale drilling operations. This bit is installed by machinists, toolmakers, and precision fabricators working in metal, composite, or printed circuit board materials.\u003c\/p\u003e\n\u003cp\u003eThe A-6100072R belongs to the ACCUPRO Miniature Series, suited for small-diameter, close-tolerance drilling on CNC machining centers, drill presses, and manual precision machines. At 30.00 mm overall length and a 1.50 mm shank diameter, it fits standard miniature collets and chucks. The 5.60 mm flute length is appropriate for shallow-to-moderate depth holes typical in miniature component and electronics manufacturing applications. Right-hand cutting direction is standard for conventional spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0283-inch cutting diameter for high-precision miniature drilling\u003c\/li\u003e\n  \u003cli\u003e120-degree drill point angle for stable, centered entry\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction resists wear in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish maintains true diameter with no coating buildup\u003c\/li\u003e\n  \u003cli\u003eSpiral flute with straight-cylindrical shank for reliable chip evacuation and easy collet mounting\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC and manual spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style miniature series drill bit compatible with standard collets and chucks accepting a 1.50 mm straight-cylindrical shank, suitable for CNC machining centers and precision drill presses used in small-diameter drilling operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or toolroom technicians familiar with micro-diameter tooling. Ensure the machine spindle is fully stopped and the tool-holding collet or chuck is clean and undamaged before seating the bit. At sub-0.030-inch diameters, runout in the spindle or collet directly increases risk of breakage — verify runout is within the machine specification before drilling. Handle micro carbide bits with care; carbide is brittle and will fracture if dropped or laterally stressed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0283 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: 30.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.50 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\u003ePackage Dimensions\u003c\/strong\u003e: 1.75 inches L x 2.25 inches W x 0.25 inches H\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-6100072R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51745167507762,"sku":"A-6100072R","price":200.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d883123ec5d1a44bee01bc52d1887f9.jpg?v=1788863120","url":"https:\/\/voomisupply.com\/products\/accupro-a-6100072r-micro-drill-bit-0-0283-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
