Hertel E6250056 Ball End Mill 0.875 in 4 Flute Carbide

Product Description

The HERTEL E6250056 is a single-end ball end mill designed for precision milling operations in metal and alloy materials. Built from micrograin solid carbide, this tool delivers superior hardness and wear resistance compared to high-speed steel alternatives. It features a 0.875-inch cutting diameter, a 1.5-inch length of cut, and a 30-degree right-hand helix for efficient chip evacuation. A titanium nitride (TiN) coating reduces friction and extends tool life. This end mill is installed by machinists and toolroom professionals working on CNC mills and manual milling machines.

This end mill is suited for finish and semi-finish milling of ferrous and non-ferrous metals in both production and job-shop environments. The ball nose profile makes it particularly effective for contour milling, 3D profiling, and slotting in die and mold work. Its 4-flute geometry supports higher feed rates and improved surface finish on hardened and general-purpose materials. The 0.875-inch shank diameter matches the cutting diameter for direct collet or end mill holder mounting on standard milling spindles.

Key Features

• Micrograin solid carbide construction for extended tool life and rigidity
• TiN coating reduces friction and improves wear resistance in ferrous materials
• 4-flute, right-hand cutting and flute direction for higher feed rate capability
• 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Ball nose end profile optimized for contour and 3D profile milling
• Single-end design for direct holder mounting without reversing

Compatibility

Designed as a standard-shank ball end mill compatible with collet chucks, end mill holders, and shrink-fit tooling systems accepting a 0.875-inch shank diameter on CNC and manual milling machines.

Installation Notes

This tool is installed by qualified machinists or toolroom technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the specified clamping torque of the tool holder manufacturer using calibrated tooling. Inspect the cutting edges for chips or wear before each use and do not exceed the tool's rated depth of cut or feed rate for the workpiece material.
