Harvey Tool 739493 Square End Mill 3/32 in 5 Flute Solid Carbide

Product Description

The HARVEY TOOL 739493 is a 5-flute solid carbide square end mill designed for high-performance milling in tight-tolerance applications. With a mill diameter of 0.0930 inches (3/32 inch) and a stub-length cutting flute of 0.14 inches (9/64 inch), this tool is built for miniature and precision machining work. The solid carbide construction delivers rigidity and wear resistance in demanding materials. Right-hand cutting and right-hand spiral flute geometry promote efficient chip evacuation. The bright, uncoated finish suits a wide range of workpiece materials without the risk of coating delamination in abrasive cuts.

This end mill fits standard CNC machining centers, vertical mills, and high-speed spindles. It is intended for machinists, toolmakers, and CNC programmers working in industries that require miniature feature machining — including medical device, aerospace, electronics, and precision die work. The 1/8-inch straight cylindrical shank fits standard collets and tool holders common in small-diameter tooling setups. The 1.5-inch overall length keeps deflection low during finish passes in shallow cavities.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard materials
• 5-flute design increases feed rates and improves surface finish compared to standard 2- or 4-flute tools
• 0.0930-inch (3/32 inch) mill diameter for miniature slot, profile, and contour work
• Centercutting geometry allows plunge entry without a pre-drilled pilot hole
• Right-hand spiral flutes with stub cutting length reduce deflection in precision passes
• Bright/uncoated finish compatible with a broad range of ferrous and non-ferrous materials

Compatibility

Designed as an OEM-style miniature square end mill for use in CNC machining centers and manual mills equipped with collets or tool holders accepting a 0.125-inch (1/8 inch) straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before installing or changing tooling. Seat the shank fully into the collet to the recommended insertion depth and torque the collet nut per the tool holder manufacturer specification. Inspect the cutting edges for chips or damage before each use, as solid carbide is brittle and sensitive to improper handling or interrupted cuts.
