Cleveland C80040 4-Flute Carbide End Mill

The Cleveland C80040 is a square end mill designed for general milling applications. Its four-flute carbide construction provides rigidity for profiling and slotting tasks. Machinists and maintenance technicians use this tool for precise material removal in metalworking shops. The TiAlN coating enhances wear resistance during dry cutting operations.

Practical limits of the straight shank interface

The straight shank with a .5 inch diameter fits standard ER collets and Weldon holders without adapters. A 2 1/2 inch overall length limits reach in deep cavities or long overhang setups. The .625 inch length of cut restricts axial depth per pass to maintain tool stability. Non-coolant-through design requires external flood or mist coolant for chip evacuation in sticky materials.

The .5 inch milling diameter decides fit

This cutter produces a .5 inch wide slot or profile in a single pass. Shops needing smaller radii or narrower channels must select a different diameter tool. The fixed geometry cannot be altered for stepped features or custom corner radii. Buyers who need more cutting length or a necked shank for clearance should choose another model.

Questions about this item

Which diameter and length of cut should I choose for my milling job?

This end mill has a 0.5 in milling diameter and a 0.625 in length of cut, suited for slots or profiles matching those dimensions.

What does the 0.5 in diameter mean when the tool is in the spindle?

It sets the cut width to half an inch per pass, determining the material removal rate and the minimum internal corner radius you can machine.

How does the straight shank interface limit use on different holders?

The 1/2 in straight shank fits standard collets and end mill holders, but cannot be used in coolant-through tooling because the tool is non-coolant through.
