Hertel E5022005 Square End Mill 5/64 in 2 Flute Carbide

Product Description

The HERTEL E5022005 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.0781-inch (5/64 inch) cutting diameter and a 0.125-inch length of cut, this tool delivers tight-tolerance profiling and slotting in a compact form factor. The 2-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation, reducing heat buildup during cuts. The uncoated solid carbide construction provides rigidity and wear resistance suitable for a range of workpiece materials. Centercutting capability allows for direct plunge entry without a pre-drilled pilot hole, adding versatility to the tool path.

This end mill is suited for light-duty milling operations requiring a small-diameter tool with a 0.125-inch shank. Typical applications include slotting, profiling, and contouring on CNC machining centers and manual mills where fine detail work demands a sub-1/8-inch cutting diameter. The 1.5-inch overall length keeps the tool rigid, minimizing deflection during passes. Machinists working on mold components, prototype parts, and precision fixtures will find this geometry well-matched to close-tolerance work at reduced depths of cut.

Key Features

• Solid carbide construction for rigidity and extended tool life
• 0.0781-inch (5/64 inch) cutting diameter for fine detail milling
• 2-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry
• Right-hand cut with uncoated finish for broad material compatibility
• Double-end configuration extends usable tool life

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 0.125-inch straight shank end mill.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully powered down and locked before changing tooling. Secure the 0.125-inch shank in a collet or end mill holder to the appropriate engagement depth to minimize runout and deflection. Always verify tool overhang and depth of cut against the machine's rated capacity before beginning a program.
