Harvey Tool 823050 Square End Mill 0.05 in 3 Flute Carbide

Product Description

The HARVEY TOOL 823050 is a solid carbide square end mill designed for precision milling operations in metalworking, toolmaking, and machining applications. With a 0.05-inch cutting diameter and a 1.9 mm (0.075 inch) length of cut, this tool is built for tight-tolerance work in confined areas, thin walls, and small-feature geometries. The three-flute design balances chip evacuation with edge strength, making it well-suited for both slotting and profiling passes. A 30-degree helix angle promotes smooth cutting action and reduces deflection at this diameter. Machinists and toolroom professionals install this end mill in CNC machining centers and manual mills requiring fine-detail capability.

This end mill is intended for use in precision machining environments where small-diameter tooling is required. Typical applications include mold and die work, prototype machining, aerospace component finishing, and medical device manufacturing where tight tolerances and small features are standard. The 1/8-inch shank diameter fits standard collets and tool holders commonly found in benchtop CNC machines and full-size vertical machining centers. The bright uncoated finish makes it appropriate for a range of ferrous and non-ferrous materials where coating compatibility must be considered.

Key Features

• 0.05-inch cutting diameter for small-feature and tight-tolerance milling
• Solid carbide construction provides rigidity and wear resistance at small diameters
• Three-flute geometry balances chip clearance and cutting edge strength
• 30-degree right-hand helix angle reduces cutting forces and deflection
• Centercutting capable, allowing plunge entry into workpiece material
• Bright uncoated finish suitable for general-purpose and non-ferrous applications

Compatibility

Designed for use in CNC machining centers and manual mills equipped with 1/8-inch collets or tool holders. Fits standard ER-series and other common collet systems accepting a 0.125-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with small-diameter carbide tooling. Ensure the collet and holder are clean and free of debris before seating the shank to the recommended insertion depth. Carbide tooling at this diameter is brittle and susceptible to breakage from side loading or improper runout — verify spindle and holder runout before use. Follow the machine manufacturer and tooling manufacturer feed and speed recommendations for the specific workpiece material.
