Widia 5825689 Ball End Mill 1/2 in 4 Flute Solid Carbide Tialn

Product Description

The WIDIA 5825689 is a solid carbide ball end mill designed for precision milling of contoured surfaces, pockets, and complex 3D profiles. Built on the Series I4B platform, it features a 1/2 inch cutting diameter, four flutes, and a TiAlN (titanium aluminum nitride) PVD coating that extends tool life at elevated cutting temperatures. The 30-degree medium helix angle balances chip evacuation with cutting edge stability. This tool is suited for both roughing and finishing passes, making it a versatile choice for machine shops and tool rooms running CNC machining centers.

This ball end mill is engineered for use on steel, stainless steel, cast iron, aluminum and non-ferrous alloys, high-temperature alloys, and hardened materials. Its single-end, right-hand cutting and right-hand flute configuration fits standard CNC milling setups. The 1/2 inch straight-cylindrical shank seats directly in standard collet chucks and end mill holders. The 1 inch length of cut and 1 inch reach length make it appropriate for moderate-depth cavities in die and mold work, aerospace component machining, and general precision part manufacturing.

Key Features

• Solid carbide construction provides rigidity and wear resistance compared to HSS alternatives
• TiAlN PVD coating improves heat resistance and extends tool life in ferrous and high-temp alloy cutting
• Four-flute design supports both roughing and finishing material removal in a single tool
• 30-degree medium helix angle promotes smooth chip flow and stable cutting forces
• Center-cutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand spiral flute direction compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-specification solid carbide ball end mill for use in standard 1/2 inch collet chucks, shrink-fit holders, and end mill holders on CNC vertical and horizontal machining centers. Primary workpiece materials include steel, stainless steel, cast iron, aluminum and non-ferrous metals, high-temperature alloys, and hardened materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the straight-cylindrical shank fully into the holder and torque the clamping mechanism to the holder manufacturer's specification. Verify runout with a dial indicator before beginning any cut, as excessive runout accelerates tool wear and reduces surface finish quality.
