Cleveland C41216 Square End Mill 0.5in 4 Flute Hss

Product Description

The CLEVELAND C41216 is a double-end, four-flute square end mill designed for material removal in ferrous and non-ferrous machining applications. Manufactured from high speed steel, it delivers reliable performance in cast iron, non-ferrous metals, and steel. The tool features a 0.5 inch mill diameter, a 1 inch length of cut, and a 4.5 inch overall length. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The uncoated HSS construction makes it suitable for general-purpose shop use where regrinding and reconditioning are part of standard tooling management.

This end mill is used in vertical milling machines, knee mills, and CNC machining centers for slotting, profiling, and peripheral milling operations. The centercutting geometry allows plunge cutting directly into the workpiece without a pre-drilled entry hole. Right-hand cut and right-hand flute configuration suits standard spindle setups. The HD-4C series is built for regular-length applications in job shop and production environments working with steel, cast iron, and non-ferrous materials.

Key Features

• Double-end design doubles usable tool life before replacement
• Centercutting geometry permits direct plunge entry into the workpiece
• 30-degree helix angle promotes efficient chip evacuation
• Right-hand cut and right-hand flute for standard spindle compatibility
• Straight-cylindrical shank with Weldon flat for secure tool holding
• Uncoated high speed steel construction supports regrinding and reconditioning

Compatibility

Designed for use in standard 0.5 inch collet chucks, Weldon-style end mill holders, and side-lock holders on vertical mills and CNC machining centers. Compatible with cast iron, non-ferrous metals, and steel workpiece materials per the HD-4C series designation.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before changing tooling. Seat the Weldon flat securely against the set screw in the holder to prevent axial pull-out during cutting. Verify runout with a dial indicator after clamping before initiating a cut.
