Cleveland HSS Keyway End Mill
The Cleveland C41681 is a two-flute high-speed steel keyway end mill with centre-cutting geometry for plunge milling. It serves machinists and maintenance teams cutting precise keyways in steel and other ferrous materials. The uncoated substrate keeps tool cost low while maintaining sharp edges for clean slot finishes.
Uncoated HSS substrate
The uncoated high-speed steel construction eliminates coating delamination risk and allows easy resharpening on standard grinders. Centre-cutting capability lets the tool start slots without pre-drilling, reducing cycle time on manual or CNC machines. No additional accessories or software are bundled with this cutting tool.
3/8 inch milling diameter
The 3/8 inch cutting diameter fixes the keyway width this mill can produce, so verify the required slot size before ordering. Builders needing wider or narrower keyways must select a different diameter cutter. The inch-based shank fits standard inch collets and holders used in North American shops.

Questions about this item
How often will the high-speed steel flutes need resharpening when cutting keyways in steel?
Resharpening frequency depends on workpiece material, cutting speed and feed rate; the uncoated HSS flutes can be reground multiple times before replacement is needed.
What limits continuous cutting time before the tool overheats?
Heat buildup in the uncoated high-speed steel flutes is the first limit; reducing speed, using coolant or taking lighter cuts extends sustained operation.
How much noise and heat does the end mill generate during an all-day milling job?
Noise and heat come mainly from the machine spindle and chip evacuation; the tool itself runs warmer as flute engagement increases, so coolant helps manage both.
