With a 2.16 mm (0.0850 inch) cutting diameter and a 120-degree drill point angle, this bit delivers accurate entry geometry in hard and abrasive materials. The straight-cylindrical shank measures 3.00 mm in diameter, and the overall length is 38.00 mm. Machinist and toolroom professionals rely on solid carbide construction for its rigidity and wear resistance in small-diameter drilling where high-speed steel would deflect or dull prematurely.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for precision machining operations in metalworking, electronics manufacturing, printed circuit board fabrication, medical device manufacturing, and instrumentation work. The miniature series designation makes it appropriate for applications where drill diameter, runout control, and repeatability are critical. It is sold individually but carries a minimum order quantity of 10 units, making it practical for shop floor replenishment in production environments. The right-hand cutting direction is standard for conventional CNC and manual drill press setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003e2.16 mm (0.0850 inch) cutting diameter with 120-degree standard point angle for accurate entry\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — ready for use as-ground, no coating buildup on cutting edges\u003c\/li\u003e\n  \u003cli\u003eSpiral flute, right-hand cut, straight-cylindrical shank for standard collet and chuck compatibility\u003c\/li\u003e\n  \u003cli\u003e12.00 mm flute length with 38.00 mm overall length suitable for shallow to moderate depth holes\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement — compatible with flood, mist, or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and precision hand-held drilling equipment accepting a 3.00 mm straight-cylindrical shank.

Secure the shank fully in the collet or chuck before beginning any operation, and verify runout before drilling to prevent bit breakage. Carbide is brittle — avoid side-loading or interrupted cuts that can fracture the tool. Always verify spindle speed and feed rate are appropriate for the workpiece material and drill diameter before starting the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.16 mm (0.0850 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 12.00 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\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\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\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-6120216R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746611986738,"sku":"A-6120216R","price":289.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86706a67c64c26038ed21e3368f511b0_171f6db1-e9be-4719-921b-7722d693f84e.jpg?v=1788871749","url":"https:\/\/voomisupply.com\/products\/accupro-a-6120216r-micro-drill-bit-2-16-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
