Cleveland C40360 end mill

The Cleveland C40360 is a 3-flute powdered metal end mill designed for general milling operations in workshop environments. It suits machinists and maintenance technicians who need a reliable square-end cutter for profiling and slotting tasks. The high-helix geometry promotes efficient chip evacuation across a range of materials. This tool is not intended for buyers who require coated or carbide alternatives for high-speed production runs.

Build integration

The cutter features a Weldon flat on a 1 in shank for secure clamping in standard end-mill holders. Its 3 in length of cut and 5 1/2 in overall length provide reach for deeper cavities without needing an extended holder. The uncoated powdered metal substrate handles moderate cutting speeds in steel and cast iron. Builds requiring through-coolant channels or corner-radius profiles cannot use this tool.

Accessory impact

No accessories, coatings or software are bundled with this end mill. The uncoated finish means the user must supply appropriate cutting fluid or mist for the workpiece material. There is no manufacturer-supplied tool-management data or wear-tracking system included. Operators needing pre-set tool-length offsets or coated performance must source those separately.

Questions about this item

How deep can the 3-inch length of cut go before chip evacuation becomes the limiting factor?

The 3-inch length of cut allows deep pocketing, but sustained full-depth slotting fills the three flutes quickly; reduce radial engagement or use peck cycles to prevent chip packing.

Does the uncoated powdered metal body run hot enough to need flood coolant during long production runs?

Powdered metal HSS-E handles heat better than standard HSS, yet the uncoated surface increases friction; flood coolant is recommended for continuous profiling to control temperature and extend edge life.

Will the 1-inch Weldon flat shank lock directly into my existing ER collet holder?

No, a Weldon flat requires a side-lock holder or a Weldon-compatible adapter; an ER collet alone will not grip the flat securely.
