Harvey Tool 823020 Square End Mill 0.5mm 3 Flute Carbide

Product Description

The HARVEY TOOL 823020 is a solid carbide square end mill designed for precision milling of small-diameter features in tight-tolerance machining applications. With a 0.5 mm (0.0200 inch) cutting diameter and a 1/32 inch length of cut, this tool is built for micro-machining work where dimensional accuracy and tool rigidity are critical. The three-flute geometry provides a balance between chip evacuation and cutting edge support, and the 30-degree helix angle promotes smooth, stable cutting action. The bright, uncoated finish makes it suitable for non-ferrous metals, plastics, and other materials that do not require a specialized coating for heat management.

This end mill is used in CNC milling operations requiring fine detail work, including mold and die machining, medical component manufacturing, electronics, and prototype fabrication. The 1/8 inch shank diameter and 1-1/2 inch overall length allow it to seat securely in standard collet-style toolholders found on vertical machining centers and high-speed spindle setups. It is a single-end, right-hand cut tool with right-hand flute direction, suited for conventional and climb milling passes at appropriate chip loads for the material being cut.

Key Features

• 0.5 mm (0.0200 inch) cutting diameter for micro-scale milling operations
• Three-flute design balances chip clearance with edge strength at small diameters
• 30-degree helix angle promotes smooth cutting and reduced vibration
• Centercutting geometry allows plunge entry into the workpiece
• Bright, uncoated solid carbide construction for non-ferrous and plastic applications
• Right-hand cut and right-hand flute direction for standard CNC spindle use

Compatibility

Designed for use in CNC machining centers and high-speed milling spindles equipped with collet toolholders accepting a 1/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the spindle is fully powered down and the toolholder is clean and free of debris before seating the end mill. Use an appropriate collet and torque the toolholder to the machine or toolholder specification. At 0.5 mm diameter, this tool is extremely fragile — verify correct speeds, feeds, and runout before cutting to avoid tool breakage.
