Cleveland C33201 4-Flute HSS End Mill
This 4-flute high-speed steel end mill is built for general-purpose milling in ferrous and non-ferrous materials. The center-cutting square profile allows plunge cuts and slotting without a pre-drilled hole. Machinists and maintenance technicians use it for profiling, pocketing and facing operations on manual or CNC mills.
TiN-coated Weldon flat shank
A titanium nitride coating reduces friction and extends edge life during repetitive cuts. The 3/8 in Weldon flat shank locks securely in standard end-mill holders, preventing pull-out under heavy radial loads. Non-coolant-through design means external flood or mist cooling is required for chip evacuation and temperature control.
Replaces uncoated HSS or worn cobalt tools
Shops upgrading from bare high-speed steel gain longer runs between regrinds and better surface finish on steel and cast iron. The jump is worth it when tool changes slow batch work or when chatter marks appear on finished walls. Not suited for high-feed carbide strategies or hardened steels above typical HSS hardness limits.

Questions about this item
What shank standard does the 3/8 in Weldon flat on this end mill follow?
The 3/8 in shank uses a Weldon flat, which conforms to the standard Weldon shank interface for set-screw or collet holders.
What holder clearance does the 2 11/16 in overall length and 1 in length of cut require?
The tool needs at least 2 11/16 in of axial clearance in the holder, with the 1 in flute length fully engaged in the cut.
How is the TiN-coated HSS cutter installed in a Weldon holder, and what step is often missed?
Align the Weldon flat with the set screw, tighten firmly, then verify the 1 in length of cut clears the workpiece before starting the spindle.
