Cleveland C33818 Square End Mill 3/8 in 2 Flute Hss Ticn

Product Description

The CLEVELAND C33818 is a single-end square end mill designed for precision material removal in milling applications. Built from high speed steel (HSS) and coated with titanium carbonitride (TiCN), this tool delivers improved wear resistance and surface hardness compared to uncoated HSS tooling. It features a 3/8 inch mill diameter, a 9/16 inch length of cut, and a 2-1/2 inch overall length. The 30-degree helix angle promotes efficient chip evacuation, and the centercutting geometry allows for direct plunge entry. This end mill is installed by machinists and tool-and-die professionals using standard milling machines and CNC machining centers.

The C33818 is suited for milling cast iron, non-ferrous metals, and steel in both production and job-shop environments. Its regular length classification and 3/8 inch straight cylindrical shank with a Weldon flat make it compatible with standard end mill holders and set-screw style toolholders. It performs well in light-to-moderate material removal passes where tool rigidity and coating life are priorities over extended reach or deep-cavity work.

Key Features

• TiCN coating increases surface hardness and wear resistance over uncoated HSS
• 30-degree right-hand spiral flutes promote efficient chip evacuation
• Centercutting geometry allows plunge milling without pre-drilled entry holes
• Weldon flat on straight shank reduces slippage in set-screw toolholders
• 2-flute design provides larger chip gullets for softer and gummy materials
• HG-2 series construction for consistent dimensional tolerances

Compatibility

Designed for use with cast iron, non-ferrous metals, and steel workpieces. Compatible with standard 3/8 inch end mill holders and Weldon-style set-screw toolholders on manual and CNC milling equipment.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and the tool is secured before commencing any cutting operation. Proper runout inspection after installation is recommended to confirm concentricity and avoid premature tool wear. Follow machine manufacturer specifications for spindle speed and feed rates appropriate to the workpiece material and tool diameter.
