Hertel E5062040 Ball End Mill 0.625 in 4 Flute Solid Carbide

Product Description

The HERTEL E5062040 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.625 inch cutting diameter and a 3 inch length of cut, this single-end tool delivers consistent performance in profiling, contouring, and 3D surface milling applications. The 4-flute geometry with a 30-degree helix angle promotes chip evacuation and smooth cutting action. At 6 inches overall length and an uncoated carbide substrate, this end mill is suited for shops running dry or with minimal lubrication on hardened and general-purpose workpieces. Machinists and tool-and-die professionals rely on this geometry for accurate radius generation at the tool tip.

This ball end mill is used in CNC machining centers and manual mills for finish and semi-finish passes on molds, dies, and contoured part features. The 5/8 inch shank diameter fits standard ER collet chucks and end mill holders commonly found in vertical machining centers. Right-hand cut and right-hand flute direction make it compatible with conventional spindle rotation on most CNC platforms. Applications include profiling hardened tool steels, aluminum, and stainless alloys where a consistent ball nose radius is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• Ball nose geometry produces accurate radii in 3D contouring and profiling passes
• 4-flute design balances chip removal with surface finish quality
• 30-degree helix angle supports smooth cutting action and reduced chatter
• Uncoated finish allows use across a broad range of materials without coating compatibility concerns
• Single-end configuration with 0.625 inch shank for secure tool-holder engagement

Compatibility

Designed as an OEM-style solid carbide ball end mill replacement fitting standard 5/8 inch end mill holders and ER collet systems used in CNC vertical machining centers and conventional knee mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 5/8 inch shank fully into the collet or end mill holder and torque the retention mechanism per the tool-holder manufacturer specification. Inspect the tool tip and cutting edges for chips or damage before each setup.
