Harvey Tool 873816 Square End Mill 1/4 in 3 Flute Carbide

Product Description

The HARVEY TOOL 873816 is a solid carbide square end mill designed for precision milling operations in metalworking, woodworking, and composite machining environments. It features a 1/4 inch cutter diameter with a 3/4 inch length of cut, a 40-degree helix angle, and three flutes arranged in a downcut configuration. The bright, uncoated finish suits applications where coating interaction with the workpiece material is a concern. This tool is installed and operated by machinists and CNC programmers working on manual and CNC milling equipment.

The 873816 is suited for single-end milling operations requiring a right-hand cutting direction. The downcut flute geometry pushes chips downward, which helps produce cleaner top-surface finishes on laminates, composites, and veneered materials. The 1/4 inch shank diameter fits standard collets and tool holders on both benchtop and production CNC mills. Overall length is 2.5 inches, keeping the tool rigid and reducing deflection during cuts.

Key Features

• Solid carbide construction for rigidity and wear resistance
• Downcut flute geometry for improved top-surface finish quality
• 3 flutes with 40-degree helix angle for balanced chip evacuation
• Bright, uncoated finish suitable for a broad range of workpiece materials
• Right-hand cutting direction, single-end configuration
• 1/4 inch shank diameter fits standard collets and ER-style tool holders

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC and manual milling machines accepting a 1/4 inch shank diameter collet or tool holder.

Installation Notes

Installation is performed by a qualified machinist or CNC technician. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Seat the shank fully in the collet or tool holder and torque the collet nut to the tool holder manufacturer's specification. Verify runout with a dial indicator before starting the cut to prevent premature wear or tool failure.
