Harvey Tool 20350-C3 Micro Drill Bit Size 54 Solid Carbide

Product Description

The HARVEY TOOL 20350-C3 is a solid carbide micro drill bit designed for precision drilling in demanding applications. 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.

This 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.

Key Features

• Wire gauge size 54 with a 0.0550-inch decimal diameter for precise small-hole drilling
• 130-degree point angle reduces thrust and improves centering on hard materials
• AlTiN coating provides elevated heat resistance and extended tool life
• Solid carbide construction delivers rigidity and wear resistance at miniature diameters
• Spiral flute design promotes chip evacuation in deep or tight drilling situations
• Right-hand cut orientation for standard spindle operation

Compatibility

Designed for use in standard 1/8-inch collets and drill chucks on CNC machining centers, benchtop drill presses, and similar precision drilling equipment. No specific compatible model numbers were provided by the manufacturer for this SKU.

Installation Notes

Installation and use of micro drill bits should be performed by qualified machinists familiar with small-diameter tooling protocols. 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.
