Harvey Tool 73120-C4 Square End Mill 0.12 in 4 Flute Carbide

Product Description

The HARVEY TOOL 73120-C4 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 0.12-inch cutting diameter and a 4-flute configuration, this tool delivers clean, accurate cuts in ferrous and non-ferrous materials. The amorphous diamond finish reduces friction and extends tool life in abrasive applications. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is centercutting, allowing direct plunge entry into the workpiece. It is installed by machinists and CNC operators working in job shops, tool rooms, and production machining facilities.

This end mill is suited for small-feature milling operations requiring tight tolerances and a fine surface finish. The 23/64-inch length of cut (0.36 inches) supports both shallow and moderate-depth passes. The 1/8-inch shank diameter fits standard collets and tool holders on vertical machining centers, CNC mills, and manual knee mills. Right-hand cut and right-hand flute geometry is the standard configuration for conventional and climb milling in most shop setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• Amorphous diamond finish reduces cutting friction and improves tool longevity
• 4-flute design increases feed rate capability and improves surface finish
• 30-degree helix angle promotes efficient chip flow and reduced cutting forces
• Centercutting geometry enables direct plunge milling without a pre-drilled hole
• Right-hand cut and right-hand flute for standard CNC and manual mill setups

Compatibility

Designed for use in standard 1/8-inch collets and tool holders on CNC vertical machining centers and manual mills. No specific model compatibility data was provided by the manufacturer for this SKU.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet to the minimum clamping depth recommended for the tool holder in use. Verify runout with a dial indicator before beginning cuts, as small-diameter carbide end mills are sensitive to runout-induced breakage.
