Hertel E5022016 Square End Mill 1/4 in 2 Flute Carbide

Product Description

The HERTEL E5022016 is a double-end square end mill ground from solid micrograin carbide. It carries a 1/4 inch diameter with a 1/2 inch length of cut and a 2-1/2 inch overall length. The 30-degree helix angle and two right-hand spiral flutes promote chip evacuation and reduce cutting forces in a wide range of milling operations. The bright, uncoated finish suits applications where coating buildup or heat sensitivity would be a concern. Machinists and tool-and-die technicians use this end mill for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials.

This end mill is suited for light-to-moderate material removal in CNC and manual milling applications. The double-end configuration extends tool life by providing two usable cutting ends, making it a practical choice for high-volume job shops and production environments. The 1/4 inch shank diameter fits standard collets and end mill holders commonly found on vertical machining centers and knee mills. Center-cutting capability allows direct plunge entry without pre-drilling.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• Double-end design provides two cutting ends per tool
• 30-degree helix angle promotes smooth chip flow and reduces chatter
• Center-cutting geometry permits direct plunge milling
• Right-hand cut and right-hand flute direction for standard spindle operation
• Bright, uncoated finish compatible with a broad range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use end mill for standard 1/4 inch collet chucks and end mill holders on vertical milling machines and CNC machining centers.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control placed in a safe, locked-out state per applicable shop safety procedures. Seat the shank fully into the collet or holder before torquing to the tool holder manufacturer's specification. Inspect the cutting edges for chips or damage before each use. Do not exceed the rated depth of cut or feed rate for the workpiece material and tool diameter.
