Harvey Tool 73115-C4 Square End Mill 0.115in 4 Flute Carbide

Product Description

The HARVEY TOOL 73115-C4 is a solid carbide square end mill designed for precision milling operations in demanding machining environments. With a 0.1150-inch cutting diameter and four flutes, this end mill delivers clean, accurate cuts in a compact form factor suited for fine-detail work. The 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. An amorphous diamond coating increases surface hardness and lubricity, extending tool life in abrasive or high-wear applications. Machinists and CNC operators working in tool rooms, job shops, and production environments use this end mill for slotting, profiling, and pocketing in both ferrous and non-ferrous materials.

This end mill is suited for use in CNC machining centers and manual mills where small-diameter, high-precision work is required. Its 0.125-inch shank diameter fits standard 1/8-inch collets and toolholders. The 0.345-inch length of cut accommodates typical shallow-to-medium depth passes in small-part machining. With a 1.5-inch overall length, it fits standard tool-length offsets for benchtop and full-size CNC setups. It is centercutting, allowing plunge entry directly into the workpiece where required.

Key Features

• 0.1150-inch cutting diameter for fine-detail and small-feature milling
• Amorphous diamond coating for improved wear resistance and surface finish
• 4-flute geometry balances chip load capacity with finish quality
• 30-degree right-hand helix with right-hand cut for efficient chip flow
• Centercutting design allows direct plunge entry
• Solid carbide construction for rigidity and dimensional stability at speed

Compatibility

Designed to fit standard 1/8-inch collets and compatible toolholding systems used in CNC machining centers and milling machines that accept small-diameter solid carbide end mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before loading or unloading tooling. Seat the shank fully into the collet to the recommended engagement depth and torque the collet nut per the toolholder manufacturer specifications. Verify tool runout with a dial indicator before beginning a production run, as runout is especially critical at small diameters.
