Harvey Tool 898216 Square End Mill 1/4 in 2 Flute Carbide

Product Description

The HARVEY TOOL 898216 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. It features a 1/4 inch cutter diameter with a 3/4 inch length of cut and a 40-degree helix angle, producing an upcut chip evacuation that helps clear material and reduce heat buildup at the cutting zone. With 2 flutes and a bright uncoated finish, this end mill suits applications where surface finish and dimensional accuracy matter. Machinists and toolroom professionals install and run this tool on CNC machining centers and manual mills where close-tolerance work is required.

This end mill is suited for slotting, profiling, and peripheral milling in a range of materials. The single-end configuration and right-hand cutting direction make it a standard choice for general-purpose milling in job shop, production, and toolroom environments. The 1/4 inch shank diameter fits common toolholding systems including ER collet chucks and end mill holders. The bright uncoated finish provides a good foundation for use in aluminum, brass, plastics, and softer steels where coating is not required.

Key Features

• 1/4 inch cutter diameter with matching 1/4 inch shank diameter for direct chuck fitment
• 3/4 inch length of cut supports slotting and side milling to moderate depth
• 40-degree helix angle with upcut flute geometry for efficient chip evacuation
• 2-flute design balances chip clearance and cutting edge strength
• Solid carbide construction provides rigidity and heat resistance versus HSS tooling
• Bright uncoated finish suitable for non-ferrous metals, plastics, and general-purpose milling

Compatibility

Designed as a standard 1/4 inch shank square end mill compatible with ER collet chucks, end mill holders, and other toolholding systems accepting a 1/4 inch shank diameter on CNC and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel familiar with CNC or manual milling equipment. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the toolholder and torque the retention mechanism to the toolholder manufacturer specification. Inspect the cutting edges for chips or damage before each use, as carbide is brittle and can fracture if dropped or mishandled.
