Hertel E5060020 Ball End Mill 0.3125 in 4 Flute Carbide

Product Description

The HERTEL E5060020 is a solid carbide ball end mill designed for precision milling operations in metal cutting and machining applications. With a 0.3125-inch mill diameter, 1.125-inch length of cut, and a 3-inch overall length, this single-end tool delivers consistent performance in contour milling, slotting, and profiling tasks. The 4-flute geometry with a 30-degree right-hand helix promotes chip evacuation and surface finish quality. The uncoated solid carbide construction provides rigidity and wear resistance suitable for a range of ferrous and non-ferrous workpiece materials. Licensed machinists and toolroom professionals typically specify this tool for CNC machining centers and manual mills requiring tight dimensional control.

This ball end mill fits standard machining applications in job shops, tool rooms, and production environments. The 5/16-inch shank diameter is compatible with common ER collet chucks and end mill holders found on vertical machining centers and milling machines. Right-hand cutting direction makes it suitable for conventional CNC mill setups. The single-end configuration is intended for direct chuck or collet mounting without flip-and-use versatility, keeping runout predictable and setup straightforward.

Key Features

• Solid carbide construction for rigidity and extended tool life compared to HSS equivalents
• 4-flute design supports improved surface finish and feed rate capability
• 30-degree right-hand helix angle promotes efficient chip flow
• Uncoated finish suitable for dry or wet cutting depending on material and application
• Single-end ball nose geometry for contour, 3D profiling, and radius milling
• 1.125-inch length of cut provides reach for moderate-depth cavity work

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard 5/16-inch collet chucks and end mill holders on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following machine tool manufacturer guidelines. Ensure the spindle is fully stopped and machine power is locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the retention mechanism per the tool holder manufacturer specification. Inspect the cutting edges for chips or damage before each use.
