Harvey Tool 946193-C6 Square End Mill 3/32 in 7 Flute Carbide

Product Description

The HARVEY TOOL 946193-C6 is a solid carbide square end mill designed for precision milling in demanding metal-cutting applications. With a 3/32-inch (0.093-inch) cutting diameter and 7 flutes, this single-end tool delivers high material removal rates while maintaining surface finish quality. The AlTiN coating provides heat resistance and extended tool life in ferrous and hardened materials. A 41-degree variable helix angle reduces harmonic vibration and chatter, making it well suited for finishing passes and aggressive slotting at tight diameters. It is installed and operated by machinists and CNC tooling professionals.

This end mill is built for small-diameter, tight-tolerance work in CNC machining centers and manual mills. The 9/64-inch (0.140-inch) length of cut suits shallow pocketing, slotting, and profiling operations where rigidity and deflection control are critical. The 1/8-inch shank diameter fits standard ER collet systems and small-bore tool holders common in precision shops. Right-hand cut and right-hand flute geometry follow conventional milling standards. The 1-1/2-inch overall length keeps the tool stiff in the spindle, reducing runout risk at high RPM.

Key Features

• 7-flute geometry increases chip load capacity and improves surface finish at small diameters
• 41-degree variable helix angle reduces chatter and harmonic vibration during cutting
• AlTiN finish provides thermal resistance and extends tool life in ferrous and hardened materials
• Solid carbide construction offers rigidity and wear resistance superior to high-speed steel
• Right-hand cut, right-hand flute — conventional milling geometry for standard spindle rotation
• Single-end design with 1/8-inch shank for compatibility with standard collet and tool holder systems

Compatibility

Designed for use in CNC machining centers and manual mills equipped with 1/8-inch collet or tool holder systems accepting standard straight-shank end mills.

Installation Notes

Installation and tool changes should be performed with the spindle fully stopped and the machine in a locked-out, de-energized state per standard lockout/tagout procedures. Seat the 1/8-inch shank fully into a clean, undamaged collet or end mill holder before torquing to the tool holder manufacturer specification. Inspect the cutting edges and AlTiN coating for chips or wear before each use — do not run a damaged carbide tool. Consult the machine and tooling manufacturer guidelines for appropriate speeds, feeds, and depth of cut for the workpiece material.
