Hertel E5251024 Ball End Mill 0.375 in 2 Flute Solid Carbide

Product Description

The HERTEL E5251024 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 0.375-inch mill diameter and a 0.5625-inch length of cut, this double-end tool delivers two usable cutting ends, extending tool life and reducing per-cut cost. The 2-flute geometry and 30-degree right-hand helix promote efficient chip evacuation during both plunge and peripheral milling. The uncoated solid carbide construction provides rigidity and hardness suited for close-tolerance work on a range of workpiece materials. Licensed machinists and CNC operators install this tool in standard end mill holders or collet chucks.

This ball end mill is appropriate for contour milling, 3D profiling, slotting, and finishing passes in job shop, tool-and-die, and production machining environments. The ball nose geometry produces radius-bottom slots and curved surface profiles. The double-end configuration makes it a practical choice for shops managing tool inventory and minimizing downtime between setups. It is sized for both manual knee mills and CNC machining centers running 3/8-inch tooling.

Key Features

• Double-end design provides two cutting ends from a single tool
• Solid carbide construction for rigidity and wear resistance
• 30-degree right-hand helix promotes effective chip evacuation
• 2-flute geometry suited for slotting and profiling operations
• Ball nose profile generates radius-bottom contours and 3D surface features
• Uncoated finish compatible with a wide range of base materials

Compatibility

Designed as an OEM-style replacement and standard fitment for 3/8-inch shank end mill holders, collet chucks, and shrink-fit tooling systems used on manual and CNC milling machines.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Secure the shank fully within the holder to the recommended gauge-line depth and torque the drawbar or collet nut per the toolholder manufacturer's specifications. Verify spindle runout with a dial indicator before production cuts. Do not exceed the tool's rated depth-of-cut or feed-per-tooth parameters for the workpiece material being machined.
