Cleveland C33411 Square End Mill 11/32 in 4 Flute Hss Ticn

Product Description

The CLEVELAND C33411 is a single-end square end mill designed for precision milling operations in machine shops and manufacturing environments. Built from high speed steel (HSS) with a titanium carbonitride (TiCN) coating, it delivers improved wear resistance and extended tool life compared to uncoated HSS tooling. The mill measures 11/32 inch (0.3438 inch) in diameter with a 1-1/2 inch length of cut, a 3/8 inch Weldon flat shank, and a 3-1/4 inch overall length. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation. This tool is intended for machinists running manual or CNC milling machines.

The C33411 is suited for milling cast iron, aluminum and non-ferrous metals, and steel. Its centercutting geometry allows plunge cuts as well as conventional peripheral and slot milling. The Weldon flat shank provides positive drive engagement in standard end mill holders and collet chucks, reducing tool pull-out risk during interrupted cuts or aggressive passes. The regular-length profile makes it appropriate for general-purpose work where extended reach is not required. Series designation is HG-4C-TC.

Key Features

• TiCN coating improves surface hardness and lubricity for longer tool life versus uncoated HSS
• Four spiral flutes with 30-degree helix angle for efficient chip removal
• Centercutting design allows direct plunge entry into workpiece material
• Weldon flat shank for secure, positive-drive tool holding
• Right-hand cut and right-hand flute orientation — standard for conventional milling setups
• Compatible with cast iron, aluminum and non-ferrous alloys, and steel workpieces

Compatibility

Designed as an OEM-style replacement or direct-use end mill for standard 3/8 inch end mill holders, Weldon-style holders, and compatible collet chucks used in manual knee mills and CNC machining centers.

Installation Notes

Installation is performed by qualified machinists following standard tool-change procedures. Power down and lock out the spindle before seating or removing the tool. Ensure the Weldon flat is properly aligned with the set screw in the tool holder to prevent rotation or pull-out during cutting. Confirm runout with a dial indicator after installation before beginning any cut.
