Cleveland C33168 End Mill
The Cleveland C33168 is a four-flute high-speed steel square end mill designed for general-purpose milling in ferrous and non-ferrous materials. Its center-cutting geometry allows plunging and slotting operations on manual or CNC machines. Machinists and maintenance technicians use it for profiling, facing and pocketing tasks where a rigid, uncoated tool is preferred.
Upgrading from two-flute or coated tools
Switching to this four-flute HSS cutter increases flute engagement for smoother finishes and higher material-removal rates in softer metals. The jump is worthwhile when chatter on two-flute tools limits feed rates or when coating buildup affects dimensional tolerance. It replaces worn uncoated end mills of the same diameter without requiring program changes.
Installation and common issues
The Weldon flat shank locks securely into standard Weldon-style end-mill holders with a set screw, so no collet nut torque sequence is needed. Problems usually arise if the holder bore is oversized or the set screw seats on the flute instead of the flat, causing run-out or tool pull-out. Verify shank-to-holder fit before cutting.

Questions about this item
Will the 1/2 in Weldon flat shank fit my tool holder?
The shank diameter is 1/2 in with a Weldon flat, so it fits standard Weldon-style end-mill holders that accept a 1/2 in shank.
How do I install this end mill without it slipping?
Insert the shank fully into the Weldon holder, align the flat with the set screw, then tighten the screw firmly against the flat to prevent rotation.
When should I replace this HSS end mill?
Replace it when the four cutting edges show visible wear, chipping, or when cut quality drops and cutting forces increase noticeably.
