Cleveland C41688 Keyway End Mill

The Cleveland C41688 is a two-flute high-speed steel keyway end mill designed for machinists cutting precise keyway slots in ferrous materials. Its center-cutting geometry allows direct plunge entry into the workpiece without a pre-drilled hole.

Uncoated HSS practical limits

High-speed steel construction provides toughness for interrupted cuts but wears faster than carbide at elevated speeds. The uncoated surface requires flood coolant or cutting oil to manage heat and prevent built-up edge when milling steel or stainless alloys.

Verify shank and holder compatibility

Confirm your tool holder accepts the shank diameter and that your machine spindle delivers adequate torque for a 5/8 inch diameter cutter. Ensure the workpiece is rigidly clamped to resist the lateral forces generated during full-width slotting passes.

Questions about this item

How do I decide between the available versions of the C41688 end mill?

The C41688 is offered as a single specification — a 5/8 inch diameter, 2-flute, high-speed steel, uncoated, center-cutting keyway end mill — so there are no alternative versions to compare.

What does the 5/8 inch milling diameter mean when the tool is in the spindle?

The 5/8 inch milling diameter is the cutting width that will produce a matching keyway slot in one pass, and the center-cutting design allows the tool to plunge directly into the workpiece.

What standard governs the shank interface and what does it limit?

The tool uses an inch-dimensioned straight shank that fits standard inch collets and holders; the shank diameter caps the maximum tool-holding capacity of the machine spindle.
