Cleveland C41204 Square End Mill 3/16 Inch 4 Flute Hss

Product Description

The CLEVELAND C41204 is a double-end, four-flute square end mill ground from high speed steel (HSS) for general-purpose milling operations. It features a 3/16-inch cutting diameter, a 1/2-inch length of cut, and a 3/8-inch straight-cylindrical shank with a Weldon flat for positive tool retention. The 30-degree spiral flute geometry promotes efficient chip evacuation, and the centercutting design allows plunge entry directly into the workpiece. Overall length is 3-1/4 inches, placing this tool in the regular-length category. It ships uncoated and is ready for immediate use.

This end mill is suited for milling cast iron, non-ferrous metals, and steel in both manual and CNC machining environments. The HD-4C series is built for shops that require a reliable HSS double-end tool at a compact diameter. Right-hand cut and right-hand flute orientation make it compatible with standard spindle configurations. Typical applications include slotting, profiling, and light pocketing passes where carbide tooling is not required.

Key Features

• Double-end design extends usable tool life before replacement
• Centercutting flute geometry allows direct plunge cutting
• 30-degree helix angle promotes smooth chip flow and reduced chatter
• Weldon flat on shank provides positive set-screw engagement and prevents tool pull-out
• Uncoated HSS construction is re-sharpenable and suited for a wide range of workpiece materials
• Right-hand cut and right-hand flute for use in standard spindle setups

Compatibility

Designed for use in milling operations on cast iron, non-ferrous metals, and steel. Fits any standard collet, end mill holder, or Weldon-flat side-lock holder accepting a 3/8-inch shank diameter.

Installation Notes

Installation and tool changes must be performed with the machine fully powered down and the spindle at a complete stop. Secure the Weldon flat against the set screw in the holder to the tool manufacturer's recommended clamping procedure before operation. Verify runout at setup with a dial indicator; excessive runout at small diameters will accelerate edge wear. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds based on workpiece material and depth of cut.
