Cleveland 80033 4-Flute Carbide HP VI Square Single End Mill .375 in

4-Flute Carbide End Mill for General Milling

This Cleveland 80033 end mill is a single-end square cutter made from solid carbide with a TiAlN coating. It suits machinists and maintenance shops that need a reliable tool for slotting and profiling in a range of ferrous and non-ferrous materials. The 4-flute design provides a balance of chip evacuation and finish quality for general-purpose milling tasks.

Sustained Cutting Behaviour and Coating Benefits

The TiAlN coating resists heat buildup during extended cuts, allowing the tool to maintain edge integrity longer than uncoated carbide when running at recommended speeds. Its straight shank and non-coolant-through construction mean heat dissipates through the workpiece and holder, so consistent feed rates and proper chip load are essential to prevent thermal shock on deep pockets or full-width slots.

Shank and Length Constraints for Machine

The 3/8 inch shank diameter fits standard ER collets and Weldon flats without requiring oversized holders. With a 2 inch length of cut and 4 inch overall length, the tool reaches moderately deep features but lacks the reach for deep-cavity work where a reduced-neck or long-reach geometry would be necessary. Rigid setups are required to minimise deflection at full axial engagement.
