Hertel E5018901 Ball End Mill 0.25in 2 Flute Solid Carbide

Product Description

The HERTEL E5018901 is a solid carbide ball end mill designed for precision milling operations in metal cutting and machining environments. With a 0.25-inch diameter and a 1.5-inch length of cut, this single-end tool delivers consistent performance in profiling, contouring, and finish milling applications. The 2-flute configuration and 30-degree right-hand helix promote efficient chip evacuation and reduce heat buildup during cutting. At 6 inches overall length with a 0.25-inch shank diameter, it fits standard collet and end mill holders used on vertical machining centers and CNC mills. The uncoated solid carbide substrate suits a wide range of base materials where coated tooling is not required.

This end mill is used in job shop, production, and tool room environments for 3D contouring, cavity milling, and radius profiling on ferrous and non-ferrous workpieces. The ball nose geometry produces a full radius at the cutting end, making it well suited for sculptured surfaces and blended transitions. Right-hand cutting direction is standard for conventional CNC milling setups. The single-end design means one cutting end per tool, which is typical for solid carbide tooling in this diameter range.

Key Features

• 0.25-inch ball nose diameter with 1.5-inch length of cut for profiling and contouring
• 2-flute, right-hand helix at 30 degrees for effective chip removal
• Solid carbide construction provides rigidity and wear resistance
• Uncoated finish suitable for applications where coating is not specified
• 6-inch overall length with 0.25-inch shank fits standard collet and shrink-fit holders
• Single-end, right-hand cutting direction for standard CNC mill compatibility

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard 0.25-inch collet chucks, end mill holders, and shrink-fit tooling systems on CNC vertical machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the control is in a safe state before loading or unloading tooling. Verify shank engagement depth meets the tool holder manufacturer minimum grip length before tightening. Inspect the cutting edges for chips or damage before each use, as carbide end mills are brittle and can fail if run with edge damage.
