Cleveland C33242 Square End Mill 5/32 in 4 Flute Hss Ticn

Product Description

The CLEVELAND C33242 is a 4-flute square end mill designed for precision material removal in ferrous and non-ferrous machining applications. Built from high speed steel (HSS) with a titanium carbonitride (TiCN) finish, this tool delivers improved surface hardness and wear resistance compared to uncoated HSS. The cutting diameter is 0.1563 inches (5/32 inch) with a 1/2-inch length of cut, a 3/8-inch straight cylindrical shank with Weldon flat, and a 2-3/8-inch overall length. The 30-degree spiral flute geometry promotes efficient chip evacuation and smooth cutting action. Installed by machinists and toolroom operators, this end mill fits standard milling machines, CNC machining centers, and manual knee mills.

This end mill is suited for slotting, profiling, and plunging operations in cast iron, non-ferrous metals, and steel. The centercutting geometry allows direct plunge entry into a workpiece without a pre-drilled pilot hole. The right-hand cut and right-hand flute configuration is the standard orientation for conventional milling setups. Series HG-4C tooling is designed for general-purpose shop use where consistent tolerances and tool life are priorities in medium-duty cutting applications.

Key Features

• TiCN coating over HSS substrate improves hardness and extends tool life in steel and cast iron
• Centercutting design allows direct plunge cutting without a pilot hole
• 30-degree helix angle with spiral flutes for effective chip evacuation
• 4-flute configuration provides a good balance of chip clearance and surface finish
• Straight cylindrical shank with Weldon flat for secure tool holding in set-screw holders
• Regular length geometry suited for standard depth-of-cut applications

Compatibility

Designed for use in standard milling machine collets and Weldon-style end mill holders accepting a 3/8-inch shank diameter. Primary workpiece materials listed by the manufacturer are cast iron, non-ferrous metals, and steel.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is de-energized or in a safe-stop state before changing tooling. Seat the Weldon flat against the set screw in the holder and torque to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a production run.
