Cleveland C33804 Square End Mill 5/32 in 2 Flute Hss Ticn

Product Description

The CLEVELAND C33804 is a 2-flute, square-end, single-end mill ground from high speed steel and finished with a TiCN coating. It carries a 5/32-inch (0.1563-inch) cutting diameter, a 7/16-inch length of cut, and a 3/8-inch straight-cylindrical shank with a Weldon flat for positive retention in the holder. The 30-degree spiral flute geometry and right-hand cut with right-hand flute direction promote efficient chip evacuation and smooth surface finish. At 2-3/8 inches overall length, the C33804 falls in the regular-length category, balancing rigidity with access in close-tolerance milling operations.

This end mill is suited to milling operations on cast iron, non-ferrous metals, and steel. The HG-2 series designation indicates a general-purpose high-speed steel platform appropriate for shops running manual mills, knee mills, and CNC machining centers where tooling cost and versatility are priorities. The centercutting geometry allows plunge entry as well as conventional and climb peripheral milling. It is typically installed by machinists and tool-and-die technicians working in job shops, maintenance departments, and production environments.

Key Features

• TiCN coating improves surface hardness and lubricity compared to uncoated HSS, extending tool life on ferrous and non-ferrous workpieces
• Centercutting design allows direct plunge milling without a pre-drilled pilot hole
• 30-degree helix angle promotes smooth chip flow and reduces cutting forces on ductile materials
• Weldon flat on the 3/8-inch shank prevents axial pull-out under load
• Right-hand cut and right-hand flute configuration compatible with standard spindle rotation on vertical mills
• Regular-length geometry maximizes rigidity and minimizes deflection in shallow-to-medium depth cuts

Compatibility

Designed for use on cast iron, non-ferrous metals, and steel workpieces. Fits any milling machine or machining center equipped with a 3/8-inch collet, end-mill holder, or Weldon-style holder. Suited to applications within the HG-2 series length-of-cut range of 0.3000 to 0.5000 inch.

Installation Notes

Installation is performed by machinists using a collet chuck or Weldon side-lock holder sized to the 3/8-inch shank. Confirm the holder set screw bears directly on the Weldon flat to prevent tool pullout during cutting. Inspect the shank and holder bore for chips or burrs before seating the tool. Follow the machine manufacturer and shop safety guidelines for spindle speeds and feed rates appropriate to the workpiece material and depth of cut.
