Cleveland C33041 Square End Mill 13/32 in 4 Flute Hss

Product Description

The CLEVELAND C33041 is a double-end, four-flute square end mill manufactured from high speed steel (HSS). Designed for general-purpose milling operations, it features a 13/32 inch (0.4063 inch) cutting diameter, a 1 inch length of cut, and a 1/2 inch straight-cylindrical shank with Weldon flat. Overall length is 4-1/2 inches. The spiral flute geometry and 30-degree helix angle promote efficient chip evacuation during slotting, profiling, and peripheral milling. This is an uncoated, centercutting tool in the HD-4C series, suited for machinists and toolroom professionals working in production or job-shop environments.

The C33041 is rated for use on cast iron, non-ferrous metals, and steel workpieces. Its double-end design extends tool life by providing two usable cutting ends per shank. Right-hand cut and right-hand flute configuration make it compatible with standard vertical and horizontal milling machine spindles. The regular-length classification and straight shank with Weldon flat allow secure clamping in standard end mill holders and collet chucks across most knee mills and CNC machining centers.

Key Features

• Double-end design provides two cutting ends per tool, reducing per-edge tooling cost
• Centercutting geometry allows direct plunge entry into the workpiece
• 30-degree helix angle promotes smooth chip flow and reduced cutting force
• Weldon flat on straight shank resists rotational slippage in standard end mill holders
• Uncoated HSS construction suitable for re-sharpening and general-purpose applications
• Four-flute configuration balances chip clearance with surface finish quality

Compatibility

Designed for use on cast iron, non-ferrous metal, and steel workpieces. Fits standard 1/2 inch end mill holders, collet chucks, and Weldon-style tool holders used on conventional and CNC milling machines.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and locked out per shop safety procedures. Ensure the Weldon flat is properly aligned with the set screw in the holder to prevent tool pullout under load. Use a torque wrench on the set screw where holder specifications require it. Inspect the cutting edges for damage before each use; do not operate a chipped or bent end mill.
