Cleveland C33193 Square End Mill 15/64 in 4 Flute Hss Tin

Product Description

The CLEVELAND C33193 is a 4-flute square end mill designed for precision milling operations in machine shops and manufacturing environments. Built from high speed steel with a titanium nitride (TiN) finish, this centercutting tool handles slotting, profiling, and peripheral milling across a range of workpiece materials. The 15/64 inch (0.2344 inch) cutting diameter pairs with a 5/8 inch length of cut and a 3/8 inch straight-cylindrical shank with Weldon flat. The 30-degree helix spiral flute geometry promotes efficient chip evacuation and stable cutting action. Machinists, toolmakers, and CNC operators are the primary users of this tool.

This end mill is suited for milling cast iron, non-ferrous metals, and steel in both manual and CNC machining setups. The regular-length body and standard 3/8 inch shank fit a wide range of collet chucks and end mill holders found on vertical machining centers and knee mills. The right-hand cut with right-hand flute configuration is the most common setup for conventional and climb milling passes in production and jobsite work.

Key Features

• Centercutting design allows direct plunge entry into workpiece material
• TiN coating increases surface hardness and extends tool life compared to uncoated HSS
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Spiral flute geometry provides consistent edge engagement across the full length of cut
• Weldon flat on shank reduces tool pullout risk under high feed loads
• Right-hand cut and right-hand flute for standard milling machine spindle direction

Compatibility

Part of the Cleveland HG-4C series; designed to fit 3/8 inch collet chucks and end mill holders with Weldon flat drive capability. Primary workpiece materials are cast iron, non-ferrous metals, and steel.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the shank fully into the collet or holder before tightening, engaging the Weldon flat set screw where the holder provides one. Confirm spindle direction matches the right-hand cut orientation before starting the machine. Inspect the cutting edges for wear or chipping before each use and replace the tool if edge integrity is compromised.
