Cleveland C40010 Corner Radius End Mill 1 in 3 Flute PM-538R

Product Description

The CLEVELAND C40010 is a corner radius end mill designed for precision milling operations in metal fabrication and machining environments. Built to PM-538R series standards, this tool features a 1-inch cutting diameter, a 3-inch length of cut (LOC), and a 42-degree helix angle that promotes smooth chip evacuation and reduced cutting forces. The bright uncoated finish makes it well-suited for applications where coating interaction with the workpiece material is a concern. It is centercutting, allowing plunge entry into a workpiece. Machinists and toolroom professionals working on CNC machining centers or manual mills are the primary users of this end mill.

This end mill is used in general-purpose milling, slotting, profiling, and contouring operations. The coarse pitch and right-hand spiral flute geometry make it effective for roughing and semi-finishing passes in ferrous and non-ferrous materials. The 3-inch LOC supports deeper cavity work without requiring extended-reach tooling. Its 1-inch shank diameter is compatible with standard ER collet chucks, side-lock holders, and hydraulic toolholders sized for 1-inch shanks. This tool is appropriate for job shops, tool and die operations, and production machining environments.

Key Features

• 1-inch cutting diameter with 3-inch length of cut for deep-cavity milling capability
• 42-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge entry without pre-drilled pilot holes
• Bright/uncoated finish suitable for materials sensitive to coated tooling
• Coarse pitch, right-hand spiral flute geometry for effective roughing and semi-finishing
• PM-538R series construction for consistent geometry and tool-to-tool repeatability

Compatibility

Designed as an OEM-specification corner radius end mill for use in standard 1-inch shank toolholders on CNC machining centers and manual milling machines. No specific machine model compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist. Secure the 1-inch shank fully into the toolholder to the minimum insertion depth recommended by the holder manufacturer before tightening. Inspect the cutting edges and corner radii for chips or damage before mounting. Follow all machine guarding and lockout/tagout procedures before changing tooling on any milling machine.
