Hertel E5249016 Ball End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The HERTEL E5249016 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and hard material applications. With a 0.25-inch diameter and a 0.75-inch length of cut, it handles contouring, profiling, and 3D surface work where a spherical cutting profile is required. The 2-flute geometry and 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The bright, uncoated carbide construction suits a range of general-purpose machining tasks. This tool is installed and operated by machining professionals, CNC programmers, and tool-and-die technicians working with vertical or horizontal milling machines.

This end mill is suited for milling centers, CNC machining operations, and manual milling work requiring a ball nose profile. The single-end configuration and fractional-inch sizing make it a direct fit for standard collet and end mill holders with a 0.25-inch bore. It is appropriate for slotting, contouring, and cavity work in production and job-shop environments. The right-hand cutting direction and right-hand spiral flutes are compatible with conventional right-hand spindle machines.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• Ball nose profile enables 3D contouring and profiled surface milling
• 30-degree helix angle promotes chip flow and reduces cutting forces
• Center-cutting design allows plunge entry without a pre-drilled pilot hole
• Bright, uncoated finish suitable for general-purpose machining applications
• Right-hand cut and right-hand spiral for use on standard spindle machines

Compatibility

Designed as an OEM-style replacement or direct-fit tooling solution for standard 0.25-inch end mill holders and collet chucks used in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before inserting or changing tooling. Seat the shank fully in the collet or tool holder to the recommended gauge line and torque the retention mechanism per the machine manufacturer's specification. Verify runout with an indicator before beginning the cut cycle.
