Cleveland C40008 Corner Radius End Mill 3/4 in 3 Flutes

Product Description

The CLEVELAND C40008 is a 3-flute corner radius end mill engineered for high-performance milling in a wide range of metal and alloy applications. Built to PM-538R series specifications, it features a 3/4-inch cutting diameter, a 3-inch length of cut (LOC), and a 5-1/4-inch overall length (OAL). The 42-degree helix angle promotes efficient chip evacuation and smooth cutting action. The bright/uncoated finish makes it well-suited for use in materials where coating adhesion is not required. This end mill is center-cutting capable, meaning it can be plunged directly into a workpiece. Machinists and tool-and-die professionals are the primary installers and operators of this tool.

The C40008 is designed for general-purpose and production milling operations on CNC machining centers and manual mills. Its coarse pitch and right-hand cutting and flute direction make it effective for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The 3/4-inch shank diameter fits standard ER collets and end mill holders commonly found in production shop environments. It is not rated for extended-reach applications.

Key Features

• 3/4-inch cutting diameter with matching 3/4-inch shank for rigid tool holding
• 3-inch length of cut (LOC) supports deep slotting and profiling passes
• 42-degree helix angle for efficient chip evacuation and smooth surface finish
• Center-cutting design allows direct plunge entry into workpiece material
• Bright/uncoated finish suitable for materials where coated tooling is not required
• Right-hand cut and right-hand spiral flute geometry for standard CNC and manual mill setups

Compatibility

Designed as an OEM-style production end mill for use in standard 3/4-inch end mill holders, ER collet chucks, and hydraulic tool holders on CNC machining centers and manual knee mills accepting 3/4-inch shank tooling.

Installation Notes

This tool is installed by machinists or tooling technicians in a machine shop environment. Always power down and lock out the spindle before changing tooling. Ensure the shank is fully seated and the tool holder is torqued to the machine manufacturer's specification using the appropriate spanner or torque wrench. Confirm runout with a dial indicator before beginning a cut to avoid premature tool wear or workpiece damage.
