Cleveland 4-Flute HSS End Mill
This 1.25 in square end mill is a center-cutting high-speed steel tool with a TiN coating. It targets machinists and maintenance teams who need a reliable cutter for slotting and profiling in general-purpose milling work.
Practical limits of the HSS substrate
High-speed steel performs well in softer materials but loses hardness quickly above moderate cutting temperatures. The TiN layer adds wear resistance, yet the tool is not suited for high-speed machining in hardened steels or exotic alloys where carbide would be required.
Upgrade path from uncoated HSS cutters
The TiN coating extends tool life and allows higher feed rates compared with uncoated high-speed steel end mills. The jump is worthwhile when cycle time and tool-change frequency matter, but it does not replace solid carbide for high-volume production.

Questions about this item
Which Cleveland end mill diameter should I choose for a 1.25 in milling operation?
The C33234 is a 1.25 in diameter square end mill with a 2 in length of cut and 4 1/2 in overall length, suited for general milling tasks.
How does the 4-flute high-speed steel design perform in a milling machine?
Four flutes on high-speed steel with TiN coating provide a good finish and wear resistance for slotting and profiling in steel and cast iron.
What does the Weldon flat shank mean for tool holding?
The 1 1/4 in shank with a Weldon flat locks into a matching end mill holder, preventing spin during heavy cuts.
