Cleveland C33099 Double End Mill

The Cleveland C33099 is a four-flute high-speed steel square end mill designed for centre-cutting milling operations. Its double-ended configuration provides two cutting ends in a single tool, extending usable life for general-purpose machining tasks. The Weldon flat shank ensures secure clamping in standard tool holders for reliable performance.

TiN Coating and Centre-Cutting Geometry

A titanium nitride coating reduces friction and wear at the cutting edges, allowing higher speeds and longer tool life compared to uncoated high-speed steel. Centre-cutting geometry enables the mill to plunge directly into the workpiece without a pre-drilled hole, simplifying pocketing and slotting workflows. The non-coolant-through design suits shops that rely on external flood or mist coolant systems.

1.875 Inch Length of Cut and 1 Inch Shank

With a 1.875 inch length of cut and a 1 inch diameter shank, the tool offers substantial reach for deep pockets while maintaining rigidity in heavy cuts. The 1 inch milling diameter matches the shank size, eliminating a reduced neck that could deflect under load. Overall length of 6 3/8 inches fits standard tool changers and manual holders alike. Builders needing longer reach or smaller diameters will require a different tool.

Questions about this item

When will the TiN coating on the 4-flute HSS cutting edges need replacement?

The TiN coating wears gradually; replace the end mill when the coating is gone and the underlying high-speed steel dulls enough to affect cut quality.

What limit appears first during a long milling pass with the 1.875 in length of cut?

Heat buildup in the high-speed steel flutes typically becomes the limiting factor before tool deflection on a sustained cut of this depth.

How much heat does the 1 in shank Weldon flat tool generate running all day in a milling machine?

High-speed steel with TiN coating runs warm but manageable; expect noticeable heat at the shank interface after extended heavy cuts.
