Hertel E5060040 Ball End Mill 0.625 in 4 Flute Carbide

Product Description

The HERTEL E5060040 is a solid carbide ball end mill designed for precision milling operations in metal, composites, and engineering plastics. With a 0.625-inch cutting diameter and 4-flute geometry, it delivers efficient chip evacuation and a smooth finish in both roughing and finishing passes. The 30-degree helix angle reduces cutting forces and promotes chip flow in deep-pocket and contour applications. At 5.0 inches overall length with a 2.25-inch length of cut, this single-end tool provides the reach needed for most mid-depth cavity and profile work. Machinists and tooling specialists in job shops, aerospace, and general manufacturing rely on this geometry for consistent performance in ferrous and non-ferrous applications.

This end mill is suited for CNC machining centers and manual knee mills where a ball-nose profile is required for 3D contouring, radius blending, and die and mold work. The right-hand cutting and right-hand flute direction make it compatible with standard spindle rotation. The uncoated solid carbide construction is well matched to applications where coolant is used and where re-grinding is part of the shop tooling program. It is a single-end tool, meaning once the cutting end is worn, the tool is reground or replaced rather than indexed.

Key Features

• 0.625-inch ball nose cutting diameter for smooth radial profiling and contour work
• 4-flute design balances material removal rate with chip clearance in most workpiece materials
• 30-degree helix angle reduces cutting forces and improves surface finish in deep slots and pockets
• Solid carbide construction provides rigidity and wear resistance over high-speed tool paths
• Uncoated finish allows straightforward re-grinding and suits coolant-assisted cutting environments
• Single-end, right-hand cut with right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard 5/8-inch ER or side-lock toolholders on CNC machining centers and compatible manual milling machines.

Installation Notes

Installation is performed by a machinist or tooling technician. Power down and lock out the spindle drive before seating or removing the tool from the holder. Confirm the shank is fully seated and the set screw or collet nut is torqued to the toolholder manufacturer specification. Inspect the cutting edges under magnification before first use and after any crash event.
