Cleveland C33409 Square End Mill 9/32 in 4 Flute Hss Ticn

Product Description

The CLEVELAND C33409 is a 4-flute square end mill designed for material removal and profiling in machining applications. Built from high speed steel with a TiCN (titanium carbonitride) finish, it offers improved surface hardness and wear resistance over uncoated HSS tooling. The 9/32-inch cutting diameter pairs with a 3/8-inch straight-cylindrical or Weldon flat shank for secure chuck or collet retention. A 30-degree helix angle and spiral flute geometry support efficient chip evacuation. The 1-3/8-inch length of cut handles typical slotting and peripheral milling depths on manual mills and CNC machining centers. Centercutting geometry allows plunge entry. This is a tool for machinists and tool-and-die professionals working in production or job-shop environments.

The C33409 is suited for milling cast iron, non-ferrous metals, and steel. Its regular-length classification and 3-1/8-inch overall length make it a practical choice for general-purpose work where extended reach is not required. The right-hand cut and right-hand flute configuration is standard for conventional and climb milling on vertical machining centers and knee mills. Series HG-4C tooling is positioned for performance in moderate-to-high feed-rate applications across common workpiece materials.

Key Features

• TiCN finish improves wear resistance and surface hardness compared to uncoated HSS
• Centercutting design allows direct plunge cutting without a pre-drilled hole
• 30-degree helix angle with spiral flutes for efficient chip flow
• 4-flute configuration balances material removal rate with chip clearance
• Compatible with straight-cylindrical chucks and Weldon flat holders at 3/8-inch shank
• Right-hand cut and right-hand flute for standard milling operations

Compatibility

Designed for use in 3/8-inch end mill holders with straight-cylindrical or Weldon flat retention. Suitable for cast iron, non-ferrous metals, and steel workpieces per Series HG-4C application guidelines.

Installation Notes

Installation is performed by qualified machinists. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify shank seating depth and set screw torque against the holder manufacturer's specification. Confirm correct spindle rotation direction before engaging the cut; the C33409 requires right-hand spindle rotation.
