Kennametal 5824520 Ball End Mill 1/4 in 4 Flute Carbide

Product Description

The KENNAMETAL 5824520 is a solid carbide ball end mill from the GOmill 4BN series, designed for demanding metal removal in milling applications. With a 1/4 inch diameter, a 3/4 inch length of cut, and a 4-flute spiral configuration with a 30-degree helix angle, this tool is built for both roughing and finishing passes. A multi-layer TiAlN/TiN/TiAlN PVD coating delivers heat resistance and wear protection at the cutting edge. Eccentric relief geometry increases cutting edge stability for extended tool life and reduces reconditioning cost by easing regrinding. Installed by machinists and tooling technicians in CNC and manual milling environments.

The 5824520 is suited for milling steel, stainless steel, and cast iron in production and job shop settings. Its center-cutting design allows plunging and ramping operations without a pre-drilled entry hole. The single-end, right-hand cutting and right-hand flute configuration fits standard collet and end mill holders. The straight-cylindrical shank and standard length designation make it a straightforward fit in common milling setups requiring a 1/4 inch shank toolholder.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• Multi-layer TiAlN/TiN/TiAlN PVD coating for elevated-temperature cutting performance
• Eccentric relief geometry extends cutting edge stability and simplifies regrinding
• Center-cutting design supports plunging and ramping operations
• 4-flute spiral configuration rated for roughing and finishing material removal
• 30-degree medium helix angle balances chip evacuation and cutting force

Compatibility

Designed for milling steel, stainless steel, and cast iron workpieces. Compatible with standard 1/4 inch shank collets and end mill holders used in CNC machining centers and manual knee mills. Part of the KENNAMETAL GOmill 4BN series. Manufacturers catalog number 4BN0250IR075A.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight-cylindrical shank to the full recommended engagement depth in the collet or holder and verify runout before cutting. Follow the machine tool manufacturer's torque specifications for collet nuts and tool holders.
