Kennametal 5824925 Ball End Mill 0.3937 in 4 Flute Carbide

Product Description

The KENNAMETAL 5824925 is a 4-flute solid carbide ball end mill designed for precision milling in steel, stainless steel, and cast iron. With a 10 mm (0.3937 inches) mill diameter and a 22 mm length of cut, it handles both roughing and finishing operations in a single tool. The TiAlN PVD coating provides thermal and wear resistance suited to demanding ferrous machining environments. Eccentric relief ground into the cutting geometry increases edge stability, extending tool life and maintaining surface quality across extended run times. The straight cylindrical shank follows DIN 6527 standards, making it compatible with standard collet and hydraulic toolholding systems.

This end mill is engineered for use on CNC machining centers and milling machines where ferrous workpiece materials are the primary substrate. Its GOmill 4BN series geometry targets steel (ISO P), stainless steel (ISO M), and cast iron (ISO K) applications in both roughing and finishing passes. The 30-degree helix angle provides smooth chip evacuation and balanced cutting forces. At 72 mm overall length with no extended neck, this is a standard-reach tool suited for open-pocket and general-profile milling operations where clearance is not a limiting factor.

Key Features

• TiAlN PVD coating for thermal resistance and extended tool life in ferrous materials
• Eccentric relief grinding improves cutting edge stability and surface finish quality
• 4-flute helical geometry supports both roughing and finishing in a single setup
• Straight cylindrical shank per DIN 6527 for broad toolholder compatibility
• Right-hand cut and right-hand flute direction for standard CNC spindle use
• No chipbreaker, no variable helix — consistent geometry optimized for clean finishes

Compatibility

Designed for use in standard straight-bore collet chucks, shrink-fit holders, and hydraulic chucks accepting a 10 mm shank diameter. Primary workpiece materials are steel (ISO P), stainless steel (ISO M), and cast iron (ISO K) per the GOmill 4BN series application ratings.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the toolchanger is disabled before changing tooling. Verify shank runout and holding torque per the toolholder manufacturer specifications before cutting. Observe the shank diameter tolerance of +0.000/-0.009 mm when selecting a collet or bore size to maintain concentricity.
