Cleveland C33029 Square End Mill 5/32 in 4 Flute Hss

Product Description

The CLEVELAND C33029 is a double-end, four-flute square end mill designed for precision milling in ferrous and non-ferrous metals, cast iron, and steel. Manufactured from high speed steel with a spiral flute geometry and a 30-degree helix angle, it delivers clean, efficient material removal in a wide range of machining applications. The 5/32-inch cutting diameter paired with a 7/16-inch length of cut makes this tool well suited for slotting, profiling, and peripheral milling where tight tolerances and corner sharpness are required. The uncoated HSS construction allows for easy resharpening and broad coolant compatibility.

This end mill is intended for use in manual mills, CNC machining centers, and knee mills found in job shops, tool rooms, and production environments. The HD-4C series is built for regular-length applications where a straight-cylindrical or Weldon flat shank provides secure tool holding. Primary workpiece materials include cast iron, non-ferrous metals, and steel. The centercutting design enables plunge entry, expanding the range of operations this tool can perform without a pre-drilled pilot hole.

Key Features

• Double-end design maximizes tool life by providing two usable cutting ends
• Four-flute spiral configuration for efficient chip evacuation and surface finish
• Centercutting geometry allows direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute orientation for standard spindle direction
• 30-degree helix angle balances cutting forces and surface finish quality
• Straight-cylindrical or Weldon flat shank for compatibility with standard end mill holders

Compatibility

Designed as an OEM-style replacement or direct substitute in regular-length end mill applications within the Cleveland HD-4C series; compatible with standard 3/8-inch end mill holders accepting straight-cylindrical or Weldon flat shanks.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or end mill holder to the recommended engagement depth to prevent pullout during cutting. Verify spindle direction is set to right-hand rotation before starting the cut.
