Cleveland C33272 Square End Mill 11/16 in 4-flute Hss Ticn

Product Description

The CLEVELAND C33272 is a 4-flute square end mill designed for precision milling in ferrous and non-ferrous materials. Built from high speed steel with a titanium carbonitride (TiCN) finish, it delivers extended tool life in demanding cutting applications. The cutter measures 11/16 inches (0.6875 inches) in diameter with a 1-5/8 inch length of cut and a 3-3/8 inch overall length. The 30-degree spiral flute geometry promotes efficient chip evacuation and smooth cutting action. Center-cutting capability allows plunge entry, making this tool suitable for slotting, profiling, and pocket milling operations.

This end mill is part of the Cleveland HG-4C series, intended for regular-length milling applications in machine shops and production environments. It fits a 1/2 inch straight shank and is compatible with standard collet chucks, end mill holders, and Weldon flat-style holders. Typical workpiece materials include cast iron, non-ferrous metals, and steel. It suits CNC machining centers and manual knee mills where consistent tolerances and surface finish are required.

Key Features

• TiCN coating increases surface hardness and reduces friction for longer tool life in steel and cast iron
• Center-cutting design allows direct plunge cuts without a pre-drilled entry point
• 30-degree helix angle promotes chip flow and reduces cutting forces
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Weldon flat shank option provides positive drive and prevents slippage under heavy cuts
• Regular-length geometry balances rigidity and reach for general-purpose milling

Compatibility

Designed for use with cast iron, non-ferrous metals, and steel workpieces. Fits 1/2 inch collet chucks, end mill holders, and Weldon flat-style tool holders. Part of the Cleveland HG-4C series for regular-length milling applications.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the spindle before installing or removing the tool. Seat the shank fully in the holder and torque the set screw or collet nut to the holder manufacturer specification. Inspect the TiCN coating and cutting edges for chips or wear before each use.
