Cleveland C33216 Square End Mill 3/4 in 4 Flute Hss Tin

Product Description

The CLEVELAND C33216 is a 4-flute, square-end, single-end mill engineered for metal removal in milling applications. Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it offers increased surface hardness and wear resistance compared to uncoated HSS tooling. The 3/4-inch cutting diameter pairs with a 1/2-inch straight-cylindrical or Weldon flat shank, keeping setup flexible across standard milling chucks and collets. With a 1-5/8-inch length of cut and a 30-degree spiral helix, this end mill is designed for controlled chip evacuation and consistent cut quality in production and job-shop environments.

The C33216 is suited for machining cast iron, non-ferrous metals, and steel in both manual and CNC vertical milling setups. The centercutting geometry allows plunge entry without a pre-drilled pilot hole. The right-hand cut and right-hand flute configuration is the standard orientation for conventional milling operations. This is a regular-length tool in the HG-4C series, appropriate for general-purpose profiling, slotting, and peripheral milling across a wide range of ferrous and non-ferrous workpiece materials.

Key Features

• TiN coating improves surface hardness and extends tool life versus uncoated HSS
• 4 flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design enables direct plunge entry into workpiece
• Right-hand cut and right-hand flute — standard orientation for most milling setups
• Compatible with straight-cylindrical chucks and Weldon flat holders via 1/2-inch shank
• Regular-length geometry balances reach and rigidity for general-purpose work

Compatibility

Fits standard 1/2-inch milling chucks, end mill holders, and collet systems. Suitable for use in cast iron, non-ferrous metal, and steel workpiece applications as specified for the HG-4C series.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the holder and torque the set screws or collet nut to the machine manufacturer's specification. Verify runout with an indicator before beginning a cut, and confirm spindle rotation direction matches the right-hand cut orientation of this tool.
