Cleveland Cobalt End Mill 3/4

The Cleveland Cobalt End Mill is a single-end square cutting tool built for general-purpose milling in a workshop or light-production environment. Its four-flute geometry and centre-cutting design suit machinists who need a reliable cutter for slotting, profiling and pocketing operations on ferrous materials.

Four-flute centre-cut behaviour

The four flutes provide a balance between chip evacuation and core strength, allowing the tool to maintain engagement during sustained passes without excessive deflection. Centre-cut capability lets the end mill plunge directly into the workpiece, reducing the need for pre-drilled starter holes in many setups.

Installation and common issues

The 3/4-inch shank fits standard collets and end-mill holders, so no special adapters are required for most manual or CNC mills. Breakage often occurs when the tool overhang is longer than necessary or when feed rates exceed the cobalt substrate's limits, so use the shortest practical stick-out and conservative speeds.

Questions about this item

How much heat and power draw should I expect from the 3/4-inch 4-flute cobalt end mill during continuous milling?

Heat and power depend on the machine spindle speed, feed rate, material being cut and coolant used; the tool itself has no electrical or thermal rating.

What tool holder or collet size is required to run this 3/4-inch shank end mill?

A 3/4-inch capacity collet, end-mill holder or shrink-fit holder matching your machine’s spindle taper is needed to secure the 3/4-inch shank.

Will this 3/4-inch 4-flute cobalt square end mill work in an older manual knee mill with a standard R8 spindle?

Yes, provided you use an R8-to-3/4-inch collet or end-mill holder; the tool’s 3-7/8-inch overall length fits typical R8 tooling envelopes.
