Harvey Tool 966316 Square End Mill 1/4 in 2 Flute Carbide

Product Description

The HARVEY TOOL 966316 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 1/4 inch cutter diameter and a 3/8 inch length of cut, this single-end tool delivers accurate square-shoulder and slot milling. The 2-flute, downcut geometry reduces upward chip pull and surface lifting, making it well suited for materials prone to delamination or tearout. A 20-degree helix angle and bright uncoated finish keep the tool lightweight and appropriate for non-ferrous metals, plastics, and composites. Machinists and CNC operators install this tool in standard 1/4 inch collets or end mill holders.

This end mill is used in CNC machining centers, manual mills, and high-speed spindle setups for slotting, profiling, and light pocketing operations. The downcut flute direction makes it a practical choice when workpiece surface quality on the top face is a priority. It is suited for job shops, tool rooms, and production environments working with aluminum, brass, plastics, and similar materials. The 2-1/2 inch overall length provides adequate reach for standard depth applications without excessive tool deflection.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• Downcut flute geometry reduces surface lifting and delamination on top workpiece face
• 1/4 inch cutter diameter with matching 1/4 inch shank for direct collet mounting
• 2-flute design promotes chip clearance in slotting and profiling cuts
• 20-degree helix angle suited for non-ferrous metals, plastics, and composites
• Bright uncoated finish — no coating buildup, ready for use as received

Compatibility

Designed as an OEM-style solid carbide end mill for use in any CNC or manual milling setup accepting a 1/4 inch shank with a standard collet or end mill holder.

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, locked-out state before changing tooling. Insert the shank fully into the collet or end mill holder and torque the retention nut per the holder manufacturer specifications. Verify tool runout with a dial indicator before beginning cuts, and confirm feed and speed parameters are appropriate for the workpiece material.
