Hertel E6252020 Ball End Mill 5/16 in 4 Flute Solid Carbide Tin

Product Description

The HERTEL E6252020 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 5/16-inch (0.3125 inches) mill diameter and a 0.5-inch length of cut, this tool handles contour milling, slotting, and 3D profiling in hardened and alloy materials. The four-flute geometry promotes chip evacuation and surface finish quality. A titanium nitride (TiN) coating extends tool life by reducing friction and heat buildup at the cutting edge. The double-end configuration provides two usable cutting ends, extending the value of each tool. This end mill is installed and used by machinists and tooling technicians in job shops, production floors, and maintenance environments.

This ball end mill is suited for use on CNC machining centers and manual milling machines in both production and toolroom environments. Its right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. The double-end design allows the operator to reverse the tool when one end reaches the end of its service life, maximizing material utilization. Typical applications include profiling, contouring, pocketing, and finishing cuts in ferrous and non-ferrous metals.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• TiN coating reduces friction and extends cutting edge life
• Four-flute design supports improved surface finish and feed rates
• Double-end configuration provides two cutting ends per tool
• Right-hand cut and right-hand helix for use with standard CNC and manual spindles
• No chipbreaker or variable helix — consistent, predictable cutting geometry

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide ball end mill for standard 5/16-inch collet or end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Secure the shank in a properly sized collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specifications. Verify spindle runout is within acceptable limits before beginning a cut. Never exceed the recommended depth of cut or feed rate for the workpiece material and tool diameter.
