Hertel E599924423 Ball End Mill 0.3125 in 4 Flute Carbide

Product Description

The HERTEL E599924423 is a solid carbide ball end mill designed for precise milling operations in ferrous and non-ferrous materials. The ball nose profile generates smooth contoured surfaces and is well suited for 3D profiling, slotting, and finishing passes on CNC machining centers and manual mills. At 0.3125 inches in diameter with a 0.75 inch length of cut, this end mill handles tight-tolerance work where rigidity and edge retention matter. The four-flute configuration balances chip evacuation with surface finish quality. A bright, uncoated finish makes this tool appropriate for a wide range of workpiece materials without coating compatibility concerns. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users.

This double-end ball end mill is suited for general-purpose milling applications in job shop and production machining environments. The 5/16 inch shank diameter fits standard ER and straight-bore collet chucks commonly found on vertical machining centers and knee mills. With a 3.0 inch overall length and right-hand cut, right-hand spiral flute geometry, it is a practical choice for contouring, profiling, and finish milling passes where a compact reach is appropriate.

Key Features

• Solid carbide construction for rigidity and edge retention in demanding milling operations
• Ball nose profile for 3D contouring and smooth surface finish on complex geometries
• Four right-hand spiral flutes balance chip evacuation and finish quality
• Double-end design provides two usable cutting ends per tool
• Bright, uncoated finish compatible with a broad range of workpiece materials
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or standard tooling option for 5/16 inch straight-bore and ER collet chuck holders used on CNC vertical machining centers and manual knee mills requiring ball end mill tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator familiar with proper tool holding and runout procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet or chuck. Confirm holder bore cleanliness and appropriate collet nut torque per the tool holder manufacturer specifications before machining. Verify spindle direction is set to right-hand rotation before engaging the cut.
