Harvey Tool 969332-C4 Square End Mill 1/2 in 8 Flute Carbide

Product Description

The HARVEY TOOL 969332-C4 is a solid carbide square end mill designed for high-performance milling in demanding machining applications. With a 1/2 inch cutter diameter, 1-1/2 inch length of cut, and 8 flutes, this tool delivers smooth finishes and efficient material removal in a single-end configuration. The amorphous diamond coating extends tool life and reduces friction in abrasive materials. At 4 inches overall length with a matching 1/2 inch shank diameter, it seats securely in standard collet and end mill holders. Right-hand cutting direction makes it compatible with conventional CNC and manual milling setups.

This end mill is suited for machining non-ferrous metals, graphite, composites, carbon fiber, ceramics, and other abrasive or hard materials where an amorphous diamond coating provides a significant wear advantage. The 8-flute geometry is optimized for finishing passes and high-speed light-chip-load operations rather than heavy roughing. It is used in precision CNC machining centers in both job shop and production environments by machinists and tool-and-die professionals working to tight tolerances.

Key Features

• Solid carbide construction for rigidity and long tool life in abrasive materials
• Amorphous diamond coating reduces wear and friction in non-ferrous and composite workpieces
• 8-flute design supports high-speed finishing with improved surface finish quality
• Single-end, right-hand cutting configuration for standard CNC milling setups
• 1/2 inch shank diameter fits standard ER and end mill collet holders
• 12-degree helix angle suited to the chip evacuation demands of the 8-flute geometry

Compatibility

Designed as a direct-fit replacement or upgrade for 1/2 inch shank square end mills in standard CNC vertical and horizontal machining centers accepting 1/2 inch collet or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the recommended minimum insertion depth for the holder type being used, and torque the collet nut or set screw per the holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, especially when working to tight tolerances.
