Harvey Tool 802462-C3 Square End Mill 1/16 in 4 Flute Carbide

Product Description

The HARVEY TOOL 802462-C3 is a 4-flute solid carbide square end mill engineered for precision milling in ferrous and non-ferrous materials. With a 0.062-inch cutting diameter and a 0.186-inch length of cut, this tool is built for tight-tolerance work in confined pockets and fine-detail profiles. The AlTiN coating provides heat resistance and wear protection at elevated cutting speeds. A 30-degree helix angle promotes efficient chip evacuation while reducing cutting forces. Machinists and CNC operators working with small-diameter tooling will find this mill suited to demanding finish and semi-finish passes in hardened or abrasive workpiece materials.

This end mill is intended for small-footprint milling operations where minimal runout and sharp edge definition are critical. The 0.125-inch shank diameter fits standard ER collet chucks and end mill holders commonly found on vertical machining centers and CNC mills. Its 1.5-inch overall length keeps deflection low, which is essential at this diameter. The centercutting geometry allows plunge entry without a pre-drilled pilot hole, adding flexibility in 3-axis toolpath strategies.

Key Features

• 0.062-inch cutting diameter with 0.186-inch length of cut for fine-detail milling
• AlTiN finish improves heat resistance and extends tool life in abrasive materials
• 30-degree helix angle promotes smooth cutting action and chip evacuation
• Centercutting design allows direct plunge entry without a pilot hole
• Right-hand cut, right-hand flute configuration standard for CNC milling spindles
• Solid carbide construction provides rigidity and dimensional stability at small diameters

Compatibility

Designed for use in standard 0.125-inch shank ER collet chucks and end mill holders on CNC vertical machining centers and similar milling platforms.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in an e-stop or lock-out condition before changing tooling. Seat the shank fully into the collet or holder and torque the retention nut to the toolholder specification. At this diameter, verify runout with a dial indicator before cutting, as excess runout accelerates wear and increases the risk of tool breakage.
