It measures 2.86 mm (0.1126 inches) in diameter with a 38 mm overall length and a 14 mm flute length. The 120-degree point angle and spiral flute geometry promote accurate hole entry and efficient chip evacuation. The bright, uncoated finish suits a range of base materials where coating is not required. This bit is suited for machinists, toolmakers, and precision fabricators working with CNC or manual equipment in manufacturing and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis micro drill bit is appropriate for small-hole drilling operations in metalworking, electronics assembly, and precision machining. The straight-cylindrical shank with a 3.00 mm diameter seats securely in standard collet chucks and drill chucks designed for miniature tooling. Its right-hand cut and regular spiral make it compatible with conventional-rotation spindles. The miniature series designation indicates it is built for applications where standard drill sizes are too large and dimensional accuracy is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision drilling\u003c\/li\u003e\n\u003cli\u003e2.86 mm (0.1126 inch) drill diameter with a 3.00 mm straight-cylindrical shank\u003c\/li\u003e\n\u003cli\u003e120-degree standard point angle for accurate hole entry\u003c\/li\u003e\n\u003cli\u003eSpiral flute with right-hand cut for conventional-rotation spindles\u003c\/li\u003e\n\u003cli\u003e38 mm overall length with 14 mm flute length for miniature-series applications\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable where coating compatibility is a concern\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style miniature drill bit for use in standard collet chucks and drill chucks accepting a 3.00 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this bit should be performed by qualified machinists or toolroom personnel familiar with small-diameter carbide tooling. Secure the shank fully in an appropriate collet or drill chuck before operation and verify runout is within acceptable limits, as solid carbide is brittle and sensitive to deflection. Power down and lock out the spindle before changing tooling. Avoid side-loading or using feed rates beyond the tool manufacturer recommendations for carbide micro drills, as breakage risk increases significantly below 3 mm diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.86 mm (0.1126 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 14 mm\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\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\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\u003ePoint Type\u003c\/strong\u003e: Standard\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-6120286R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51745699496242,"sku":"A-6120286R","price":291.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc4d703fd2dd5479042b7038844702a8.jpg?v=1788864819","url":"https:\/\/voomisupply.com\/products\/accupro-a-6120286r-micro-drill-bit-2-86-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
