Cleveland C33408 Square End Mill 4 Flute Hss Ticn

Product Description

The CLEVELAND C33408 is a 4-flute, single-end square end mill designed for precision material removal in milling operations. Built from high speed steel (HSS) with a titanium carbonitride (TiCN) finish, this tool offers improved surface hardness and wear resistance compared to uncoated HSS. It features a 0.25 inch cutting diameter, a 1.25 inch length of cut, and a 3/8 inch straight-cylindrical shank with a Weldon flat for positive drive. The 30-degree helix angle and spiral flute geometry support efficient chip evacuation. Intended for use by machinists and CNC operators in job shops, toolrooms, and production environments.

The C33408 is suited for milling cast iron, non-ferrous metals, and steel in applications requiring a regular-length end mill. Its centercutting design allows plunge entry, making it appropriate for slot milling, profiling, and pocketing operations. The right-hand cut and right-hand flute configuration is standard for conventional vertical milling machines and CNC machining centers. At 3-1/16 inches overall length, the tool fits standard ER and side-lock toolholders with a 3/8 inch bore.

Key Features

• 4-flute spiral geometry for improved surface finish and feed rates in ferrous and non-ferrous materials
• TiCN coating increases surface hardness and extends tool life compared to uncoated HSS
• Centercutting design enables direct plunge entry without a pre-drilled hole
• 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Weldon flat on straight-cylindrical shank provides positive drive and reduces pullout risk
• Series HG-4C regular-length geometry balances reach and rigidity for general-purpose work

Compatibility

Designed as an OEM-style replacement or direct-use tool for milling operations on cast iron, non-ferrous metal, and steel workpieces; compatible with any toolholder accepting a 3/8 inch straight-cylindrical shank with Weldon flat.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Confirm the Weldon flat is properly aligned with the toolholder setscrew before tightening. Verify tool runout with a dial indicator after installation to maintain dimensional accuracy and protect tool life.
