It is sized to wire gauge No. 55, equivalent to 0.0520 inches in diameter, and features a 130-degree split-style point angle that promotes accurate entry and reduces walking on hard or smooth surfaces. The AlTiN coating improves heat resistance and extends tool life in abrasive materials. With a spiral flute geometry and right-hand cut, this bit is suited for use in CNC machining centers, drill presses, and precision bench-top setups where small-diameter holes are required in metal, composites, or hard plastics.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit fits into the HARVEY TOOL Miniature Drills series and is intended for machinists, toolroom operators, and precision fabricators working on small-scale components. Typical applications include PCB drilling, instrument manufacturing, mold work, and aerospace or medical part production where controlled chip evacuation and dimensional accuracy are critical. The 1\/8-inch shank diameter makes it compatible with standard collets and chucks found in most benchtop and production CNC machines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 55 wire size, 0.0520 inches diameter for tight-tolerance small-hole work\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle for clean entry and reduced drill walk\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating increases surface hardness and heat resistance during high-speed cutting\u003c\/li\u003e\n  \u003cli\u003eSpiral flute design promotes efficient chip evacuation in deep or blind holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/8-inch collets and drill chucks on CNC machining centers, micro-drilling stations, and precision drill presses.

Ensure the spindle and collet are clean and within runout tolerance before seating the shank, as small-diameter carbide tools are sensitive to lateral load and vibration. Use recommended feeds and speeds for solid carbide micro drills in the workpiece material; avoid hand-feeding or excessive plunge rates that can snap the bit. Carbide is brittle — do not use this tool in a hand-held drill.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 55\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0520 inches\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: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.4130 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20340-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51734575776050,"sku":"20340-C3","price":40.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17850c947fc75af9534ccf940652f7f9_10caaaa7-bfe8-49c4-b412-793df6f285cc.jpg?v=1788763533","url":"https:\/\/voomisupply.com\/products\/harvey-tool-20340-c3-micro-drill-bit-no-55-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
