Cleveland C33283 4-Flute HSS End Mill

The Cleveland C33283 is a 4-flute high-speed steel centre-cutting square end mill with a 0.875 in milling diameter. It suits machinists and maintenance teams needing a general-purpose tool for slotting, profiling and plunging in ferrous and non-ferrous materials. The Weldon flat shank ensures secure clamping in standard holders.

Replaces worn or lower-flute cutters

Swapping to this 4-flute design from a 2- or 3-flute tool raises chip evacuation efficiency and surface finish when the machine spindle has adequate rigidity. The step is worthwhile when cycle time matters and the workpiece material allows the higher feed rates that four flutes enable. The TiCN coating extends edge life over uncoated HSS in the same application.

Fits standard Weldon holders

The 7/8 in shank diameter with a Weldon flat locks directly into common end-mill holders without collets or adapters. A 1.875 in length of cut and 4 1/8 in overall length provide reach for medium-depth pockets while keeping overhang short for rigidity. The non-coolant-through body means external flood or mist coolant must be directed at the cut zone. Not suited for through-spindle coolant systems or internal-coolant-only machine setups.

Questions about this item

What shank diameter does the Cleveland C33283 end mill need for the tool holder?

The end mill has a 7/8 in shank diameter with a Weldon flat, so the holder must accept that exact shank size and provide a set-screw flat engagement.

How is the Cleveland C33283 end mill installed in a milling machine, and what step is often missed?

Insert the 7/8 in Weldon-flat shank into a matching holder, align the flat with the set screw, and tighten securely; the step often missed is verifying the flat seats fully against the set screw before cutting.

When will the Cleveland C33283 end mill need replacement, and how can wear be checked?

Replace the HSS TiCN-coated cutter when the 0.875 in cutting diameter shows visible flank wear, chipping, or when surface finish degrades; inspect the four flutes regularly under magnification for dull edges.
