Sized to wire gauge 54 (1.40 mm \/ 0.0551 inches decimal), it features a 140-degree standard point angle that reduces walking and minimizes burr formation on entry. The spiral flute geometry promotes efficient chip evacuation. With a 50 mm overall length and a 3.00 mm straight-cylindrical shank, this bit fits standard collet chucks and drill chucks used in CNC machining centers, benchtop drill presses, and precision hand drilling operations. It is supplied bright and uncoated, making it suitable for a wide range of base materials.\u003c\/p\u003e\u003cp\u003eThis micro drill bit is used in precision machining and fabrication environments where small-diameter hole tolerances are critical. Typical applications include circuit board drilling, instrument component manufacturing, tooling fabrication, and any operation requiring consistent, repeatable micro-diameter holes. The miniature series designation indicates it is optimized for small-diameter, high-precision work. Right-hand cutting direction suits standard spindle rotation on virtually all production and benchtop drilling equipment. No coolant-through capability is required for most light-duty micro drilling setups where external coolant or air blast is sufficient.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 54 (1.40 mm \/ 0.0551 inches) for precise micro-diameter drilling\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle reduces bit walking and minimizes entry burrs\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003eSpiral flute with regular spiral type promotes efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e3.00 mm straight-cylindrical shank fits standard collet and drill chuck systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style miniature series micro drill bit compatible with standard collet chucks and drill chucks accepting a 3.00 mm straight-cylindrical shank on CNC and manual drilling equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMicro drill bits in this size range are installed and operated by machinists, tool and die makers, and precision fabricators. Ensure the spindle and chuck are fully powered down and at a complete stop before inserting or removing the bit. Secure the shank firmly in a properly sized collet or drill chuck to prevent runout, which can cause premature breakage at small diameters. Use appropriate spindle speeds and feed rates for solid carbide micro tooling — consult tooling manufacturer guidelines for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 54\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1.40 mm (0.0551 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50.00 mm (approximately 1.97 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10.00 mm (approximately 0.39 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm (approximately 0.118 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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-6200140R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737486328114,"sku":"A-6200140R","price":323.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bff9a42d2cc995262658361bd4d17447.jpg?v=1788789125","url":"https:\/\/voomisupply.com\/products\/accupro-a-6200140r-micro-drill-bit-size-54-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
