Cleveland C33812 Square End Mill 9/32 in 2 Flute Hss Ticn

Product Description

The CLEVELAND C33812 is a square end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from high speed steel with a titanium carbonitride (TiCN) finish, it offers improved wear resistance and heat tolerance compared to uncoated HSS tooling. The 9/32 inch cutting diameter, 9/16 inch length of cut, and 3/8 inch straight cylindrical shank with Weldon flat make it a reliable choice for general-purpose profiling, slotting, and peripheral milling. Two right-hand spiral flutes with a 30-degree helix angle promote efficient chip evacuation in ferrous metals, cast iron, and non-ferrous alloys.

This end mill is suited for manual mills, CNC machining centers, and knee mills running at speeds appropriate for HSS tooling. Typical applications include slot milling, contour work, and step milling in cast iron, steel, and non-ferrous metals. The centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. It is used by machinists, tool and die makers, and maintenance technicians in job shops and production environments. The regular-length configuration and 2-1/2 inch overall length provide good rigidity for standard-depth operations.

Key Features

• TiCN coating improves wear resistance and extends tool life compared to uncoated HSS
• Centercutting design allows direct plunge milling without a starter hole
• 30-degree right-hand spiral flute promotes chip evacuation and reduces heat buildup
• 3/8 inch straight shank with Weldon flat for positive drive and reduced pullout risk
• Suitable for cast iron, steel, and non-ferrous metal workpiece materials
• Series HG-2 regular-length geometry balances reach and rigidity

Compatibility

Designed as an OEM-style replacement or equivalent for standard 3/8 inch shank collet holders, end mill holders, and Weldon-flat set-screw holders used in manual and CNC milling applications.

Installation Notes

Installation is performed by qualified machinists. Secure the shank fully into the holder and engage the Weldon flat set screw to the flat to prevent axial pullout. Verify runout with a dial indicator before cutting. Select speeds and feeds appropriate for high speed steel tooling and the specific workpiece material per published machining data tables.
