Harvey Tool 968793-C8 Square End Mill 3/32 in 3 Flute Carbide

Product Description

The HARVEY TOOL 968793-C8 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 3/32-inch cutting diameter and a 9/64-inch length of cut, this tool handles slotting, profiling, and peripheral milling in a compact envelope. The 42-degree variable helix geometry reduces chatter and harmonics during the cut, improving surface finish and tool life. A titanium diboride (TiB2) coating adds surface hardness and lubricity. Three flutes balance chip evacuation with cutting edge strength, making this tool suitable for a range of workpiece materials. It is installed and used by machinists and CNC operators in job shops, tool rooms, and production environments.

This end mill is suited for small-feature milling operations where a 1/8-inch shank diameter is required. The 1-1/2-inch overall length keeps the tool rigid and minimizes deflection in high-speed CNC machining centers and manual mills. The centercutting design allows plunge entry directly into the workpiece. Applications include mold work, die making, aerospace component machining, and precision part manufacturing where fine detail and dimensional accuracy are critical.

Key Features

• 42-degree variable helix reduces chatter and improves surface finish
• TiB2 coating increases surface hardness and reduces friction at the cutting edge
• Centercutting design allows direct plunge entry into the workpiece
• Three-flute geometry balances chip clearance with cutting edge engagement
• Right-hand cut and right-hand flute for standard CNC spindle use
• Solid carbide construction provides rigidity and wear resistance in demanding cuts

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 1/8-inch straight shank. Suitable for tool holders, collets, and end mill adapters configured for 1/8-inch shank tooling.

Installation Notes

Installation is performed by machinists using a compatible collet or end mill holder rated for the 1/8-inch shank diameter. Ensure the tool holder bore is clean and free of debris before seating the shank. Confirm runout with a dial indicator before beginning production cuts. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
