Harvey Tool 941308 Square End Mill 1/8 in 3 Flute Carbide

Product Description

The HARVEY TOOL 941308 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. With a 1/8 inch cutter diameter and a 5/8 inch length of cut, this end mill is built for finishing passes, slotting, and profiling in tight geometries. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Three flutes provide a balance between chip clearance and surface finish quality. The bright/uncoated finish makes this tool well-suited for non-ferrous metals, plastics, and other materials where coating interaction is a concern. Licensed machinists and CNC operators rely on tools like this for close-tolerance work.

This end mill is used in CNC machining centers and manual milling machines for small-diameter work in die and mold making, prototype machining, and general precision manufacturing. The 1/8 inch shank diameter matches the cutter diameter, making it compatible with standard 1/8 inch collets and toolholders. The 2 inch overall length keeps the tool rigid at small diameters, reducing deflection during cuts. Centercutting capability allows plunge milling in addition to standard peripheral and slot cutting operations.

Key Features

• 1/8 inch cutter diameter with matching 1/8 inch shank for direct collet fitment
• 3-flute geometry balances chip evacuation and finish quality
• 40-degree helix angle for smooth cutting and efficient chip flow
• 5/8 inch length of cut supports slotting and profiling at small diameters
• Centercutting design enables plunge entry without a pre-drilled hole
• Bright/uncoated solid carbide construction for use on non-ferrous metals and plastics

Compatibility

Designed for use with standard 1/8 inch collets and toolholders in CNC machining centers and manual milling machines requiring small-diameter solid carbide end mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the shank fully into the collet and torque the collet nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production run, as excessive runout at small diameters accelerates tool wear and degrades finish quality.
