Harvey Tool 73071-C3 Square End Mill 1.8mm 4 Flute Carbide

Product Description

The HARVEY TOOL 73071-C3 is a solid carbide square end mill designed for high-precision milling operations in demanding machining environments. With a 1.8 mm (0.0710 inch) cutting diameter and a 4-flute geometry, it delivers smooth chip evacuation and fine surface finishes in ferrous and non-ferrous materials. The AlTiN coating provides heat resistance and extended tool life at elevated cutting temperatures. A 30-degree helix angle balances cutting efficiency with edge stability. This tool is installed and operated by machinists and CNC programmers working in precision manufacturing, tool-and-die, mold making, and aerospace component production.

This end mill suits small-feature milling applications where tight tolerances and fine detail are required. The 0.213 inch length of cut and 1.5 inch overall length make it well suited for shallow pocket milling, slotting, and contouring in compact workpiece geometries. The 0.125 inch (1/8 inch) shank diameter fits standard ER collets and other common toolholding systems used on CNC machining centers and high-speed spindles. Center-cutting geometry allows plunge entry without a pre-drilled starting hole.

Key Features

• Solid carbide construction for rigidity and dimensional stability at high feed rates
• AlTiN coating enhances heat resistance and reduces built-up edge in hard materials
• 4-flute design improves surface finish and allows higher feed-per-tooth values
• 30-degree right-hand helix balances axial cutting forces with chip flow
• Center-cutting capable — supports direct plunge entry into workpiece material
• Right-hand cutting direction compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 1/8 inch (0.125 inch) collet toolholding systems on CNC machining centers and high-speed milling spindles.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before inserting or removing the tool from the collet. Ensure the shank is fully seated and the collet nut is torqued according to the toolholder manufacturer specifications. Verify runout at the tool tip with a dial indicator before beginning a production run to prevent premature tool wear or workpiece damage.
