Cleveland C40369 Corner Radius End Mill 1in 3 Flute Ticn

Product Description

The CLEVELAND C40369 is a single-end, corner radius end mill designed for precision finishing operations in non-ferrous metal applications. Built from powdered metal and coated with a PVD-applied TiCN finish, this tool delivers extended wear resistance in demanding machining environments. It features a 1 inch cutting diameter, a 0.12 inch corner radius, and a 4 inch length of cut, making it well-suited for deeper cavity work and long-reach finishing passes. The right-hand spiral flute geometry and high helix angle promote efficient chip evacuation. Licensed machinists and CNC operators are the primary users of this tooling.

This end mill is engineered for finishing operations on non-ferrous metals, including aluminum, copper, and similar materials. Its long-reach configuration and coarse pitch make it appropriate for applications requiring extended reach into pockets, slots, or contoured surfaces. The 1 inch Weldon flat shank seats securely in compatible toolholders, providing rigid setup on vertical and horizontal machining centers. The PM-539R series is a recognized Cleveland offering for shops that prioritize consistent surface finish and dimensional accuracy in non-ferrous work.

Key Features

• TiCN coating applied via PVD process for improved hardness and wear resistance
• Powdered metal substrate provides consistent grain structure and toughness
• 0.12 inch corner radius reduces stress concentration at cutting edges
• High helix, right-hand spiral flutes promote clean chip evacuation in non-ferrous materials
• Centercutting design allows plunge entry without a pre-drilled pilot hole
• Weldon flat shank ensures positive drive and minimal slippage in toolholders

Compatibility

Designed for use with standard toolholders accepting a 1 inch Weldon flat shank. Intended for finishing operations on non-ferrous metals as indicated by the primary workpiece material designation in the PM-539R series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Before mounting, confirm the toolholder bore and set-screw alignment are compatible with a 1 inch Weldon flat shank. Secure the shank to the manufacturer-recommended clamping torque for the specific toolholder in use. Verify spindle direction is set to right-hand rotation before initiating a cut, and confirm tool runout with a dial indicator after mounting.
