Cleveland C33831 Square End Mill 9/16 in 2 Flute Hss Ticn

Product Description

The CLEVELAND C33831 is a 2-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, it delivers added surface hardness and wear resistance compared to uncoated HSS tooling. The cutter measures 9/16 inches in diameter with a 1-1/8 inch length of cut, a 1/2 inch straight-cylindrical or Weldon flat shank, and a 3-3/8 inch overall length. Its 30-degree helix angle and spiral flute geometry promote efficient chip evacuation. This tool is centercutting, allowing direct plunge entry into a workpiece without a pre-drilled hole.

The C33831 is suited for job shop and production machining environments where operators work with cast iron, non-ferrous metals, and steel. It fits standard milling machine spindles and CNC machining centers accepting a 1/2 inch shank. The regular length profile makes it a practical choice for general-purpose peripheral and slot milling where extended reach is not required. Right-hand cut and right-hand flute orientation follow conventional tooling standards for typical vertical and horizontal milling setups.

Key Features

• TiCN coating improves surface hardness and extends tool life versus uncoated HSS
• Centercutting geometry allows plunge cutting without a pilot hole
• 30-degree helix angle supports smooth cutting action and efficient chip removal
• Compatible with Weldon flat or straight-cylindrical tool holders for secure clamping
• Right-hand cut and right-hand flute — standard orientation for conventional milling
• Series HG-2 regular length classification for general-purpose slot and peripheral milling

Compatibility

Designed for use on cast iron, non-ferrous metals, and steel workpieces. Accepts standard 1/2 inch collets, end mill holders, or Weldon-style set-screw holders. Series HG-2 regular length designation.

Installation Notes

Installation is performed by a machinist or CNC operator. Secure the shank fully within the tool holder to the recommended engagement depth before tightening set screws or collet nuts. Power down and lock out the spindle before changing tooling. Always verify spindle speed and feed rate for the specific workpiece material before initiating a cut.
