Built to wire gauge size 54 with a decimal equivalent of 0.0550 inches, this bit features a 130-degree point angle and a spiral flute geometry that promotes efficient chip evacuation at small diameters. The AlTiN coating improves heat resistance and extends tool life when cutting hard or abrasive materials. Right-hand cut orientation follows standard drill press and CNC machining conventions. The 0.4130-inch flute length and 1.5000-inch overall length suit compact workpiece setups.\u003c\/p\u003e\u003cp\u003eThis micro drill is suited for precision machining in metalworking, toolmaking, mold and die work, and electronic component fabrication. The 1\/8-inch shank diameter is compatible with standard collets, drill chucks, and tool holders used on CNC machining centers, drill presses, and benchtop drilling stations. It is well suited for machinists, toolmakers, and precision fabricators working with ferrous and non-ferrous metals, hardened steels, and composite materials where dimensional accuracy at small hole sizes is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 54 with a 0.0550-inch decimal diameter for precise small-hole drilling\u003c\/li\u003e\n\u003cli\u003e130-degree point angle reduces thrust and improves centering on hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides elevated heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and wear resistance at miniature diameters\u003c\/li\u003e\n\u003cli\u003eSpiral flute design promotes chip evacuation in deep or tight drilling situations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/8-inch collets and drill chucks on CNC machining centers, benchtop drill presses, and similar precision drilling equipment.

Secure the 1\/8-inch shank fully in the collet or chuck before operation, and verify runout is within acceptable tolerance to prevent premature breakage at this diameter. Reduce feed rates and spindle speeds relative to larger drills when working with miniature bits in hardened or abrasive materials. Always power down the machine spindle completely before changing or inspecting tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 54\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0550 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 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: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 20350-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51738337182002,"sku":"20350-C3","price":41.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17850c947fc75af9534ccf940652f7f9_b8885377-f4d5-4cd3-b518-a2ab5eeb9d13.jpg?v=1788798407","url":"https:\/\/voomisupply.com\/products\/harvey-tool-20350-c3-micro-drill-bit-size-54-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
