Harvey Tool 69608-C4 Square End Mill 1/8 in 2 Flute Carbide

Product Description

The HARVEY TOOL 69608-C4 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 1/8 inch cutter diameter and a 3/8 inch length of cut, this tool is built for tight-tolerance slotting, profiling, and finishing passes in small-feature work. The straight flute geometry with a 0-degree helix and right-hand cut direction suits applications where lateral cutting forces must be minimized. The amorphous diamond coating improves surface hardness and wear resistance, extending tool life in abrasive and non-ferrous materials. This end mill is intended for use by machinists and CNC operators working on precision components.

This end mill is suited for milling operations on non-ferrous metals, plastics, composites, and graphite where an amorphous diamond finish provides measurable performance advantages. The straight flute design makes it a reliable choice for materials that benefit from reduced chip evacuation pressure. With a 1/8 inch shank diameter and 1-1/2 inch overall length, it fits standard collet toolholders and is appropriate for benchtop CNC mills, VMCs, and similar equipment requiring small-diameter tooling.

Key Features

• Solid carbide construction for rigidity and dimensional stability in precision cuts
• Amorphous diamond coating for improved wear resistance and reduced friction on abrasive materials
• Straight flute, 0-degree helix geometry reduces lateral cutting forces
• Right-hand cut and right-hand flute orientation for standard CNC spindle compatibility
• 2-flute design optimized for chip clearance in small-diameter applications
• Single-end configuration with matched 1/8 inch cutter and shank diameter for collet fitment

Compatibility

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

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 powered-down state before changing tooling. Seat the shank fully in the collet to the recommended engagement depth per the toolholder manufacturer specification. Do not exceed the tool's rated speed and feed parameters for the workpiece material.
