Cleveland C41685 2-Flute HSS Keyway End Mill
This Cleveland C41685 is a 2-flute high speed steel keyway end mill with a 1/2 in milling diameter. It features a center cutting design and single end construction for slotting operations. The uncoated tool is built to keyway tolerance standards for precise metalworking.
Machinists cutting precise keyways in steel
The tool suits operators who need a dedicated keyway tolerance cutter for accurate slot widths in ferrous materials. It is not suited for high-volume production runs where coated carbide tooling would extend tool life. Buyers requiring multi-flute finishing profiles or non-standard diameters should evaluate alternative cutter geometries.
Keyway tolerance specification for slot accuracy
The defining attribute is the keyway tolerance grind which ensures the slot width matches standard keystock dimensions. This tolerance control distinguishes the cutter from general purpose end mills that may produce oversize slots. Select this mill when the finished keyway fit is the primary quality requirement.

Questions about this item
How do I install the 1/2 in keyway end mill in my milling machine, and what step do people often miss?
Secure the 1/2 in shank fully in the collet or end-mill holder, then verify the tool runs true with a dial indicator before cutting; many skip the run-out check and get oversize slots.
What maintenance or replacement will the uncoated HSS keyway end mill need later?
The high-speed steel flutes will dull with use; plan to resharpen the 2-flute cutting edges on a tool grinder or replace the cutter once the center-cutting tip wears beyond tolerance.
What limit appears first when the Cleveland C41685 runs continuously in steel?
Heat buildup in the uncoated HSS body is the first constraint; without coolant or air blast the cutting edges lose hardness faster than the 1 in length of cut can dissipate heat.
