Harvey Tool 73052-C3 Square End Mill 0.052 in 4 Flute Carbide

Product Description

The HARVEY TOOL 73052-C3 is a solid carbide square end mill designed for precision milling operations across a range of metalworking and machining applications. With a 0.052-inch cutting diameter and a 5/32-inch (0.156-inch) length of cut, this tool is built for small-diameter work where tight tolerances and consistent finish quality are critical. The AlTiN coating improves heat resistance and tool life, making it suitable for harder materials and higher-speed cutting conditions. Four flutes provide a balance of chip evacuation and surface finish. This end mill is used primarily by machinists and CNC operators in job shops, production facilities, and toolrooms.

This end mill fits applications requiring small-diameter cutting in ferrous and non-ferrous metals, hardened steels, and similar materials where AlTiN coatings perform well. The 1/8-inch shank diameter suits standard collet systems on CNC machining centers and manual mills. With a 1.5-inch overall length and no extended reach, it is intended for close-clearance work. The 30-degree helix angle supports smooth cutting action and efficient chip flow in typical milling passes.

Key Features

• 0.052-inch cutting diameter for small-feature and fine-detail milling
• AlTiN coating for improved heat resistance and extended tool life in harder materials
• 4-flute geometry balances chip evacuation with surface finish quality
• 30-degree right-hand helix angle for smooth, efficient cutting action
• Centercutting design allows plunge entry as well as peripheral cutting
• Solid carbide construction for rigidity and dimensional stability

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills accepting a 1/8-inch shank collet.

Installation Notes

Installation and use should be performed by qualified machinists familiar with CNC or manual milling equipment. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully in a properly sized collet or tool holder and torque the retention mechanism to the machine manufacturer's specification. Verify runout with a dial indicator before beginning production cuts.
