Harvey Tool 846908-C3 Square End Mill 1/8 in 3 Flute

Product Description

The HARVEY TOOL 846908-C3 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous metals. With a 1/8 inch cutting diameter, 3/16 inch length of cut, and three flutes, this tool delivers a clean, flat-bottomed profile in slot, profile, and peripheral milling operations. The 30-degree helix angle and AlTiN coating make it well suited for high-temperature cutting environments where tool life and surface finish are critical. Extended reach geometry provides access to deeper features without sacrificing rigidity. Licensed machinists, tool-and-die workers, and CNC machine operators typically specify this end mill for tight-tolerance work.

This end mill is designed for single-end use in vertical machining centers, CNC mills, and manual knee mills. The 1/8 inch shank diameter fits standard collets and tool holders common to small-part machining setups. The extended reach configuration, with a 1-1/8 inch reach length, suits pocket milling and contour operations where standard-length tools cannot reach the workpiece. It is not a centercutting tool, so plunge milling is not recommended. Right-hand cutting and right-hand flute direction conform to standard spindle rotation on most CNC machining equipment.

Key Features

• 1/8 inch cutting diameter with 3/16 inch length of cut for small-feature precision milling
• Three-flute geometry balances chip evacuation and rigidity in tight profiles
• AlTiN coating extends tool life in elevated-temperature, high-speed machining applications
• 30-degree helix angle promotes smooth cutting action and reduced cutting forces
• Extended reach with 1-1/8 inch reach length for deep-pocket and hard-to-access feature work
• Solid carbide construction provides stiffness and wear resistance beyond high-speed steel alternatives

Compatibility

Designed as a single-end square end mill compatible with standard 1/8 inch collets and tool holders used in CNC vertical machining centers and manual milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Seat the 1/8 inch shank fully into the collet or tool holder and torque the drawbar or nut to the machine manufacturer specification. This tool is not centercutting - do not use for direct plunge operations. Confirm runout with a dial indicator before starting a production run to protect the tool and the workpiece.
