Kennametal 5824523 Ball End Mill 0.25 in 4 Flute Solid Carbide

Product Description

The KENNAMETAL 5824523 is a solid carbide ball end mill from the GOmill 4BN series, designed for precise milling in ferrous materials including steel, stainless steel, and cast iron. It features a 0.25-inch diameter with a 1.5-inch length of cut and a 6-inch overall length, making it suitable for deep-reach applications where a standard-length tool would fall short. The TiAlN PVD coating delivers thermal resistance and extended edge life under high cutting loads. The eccentric relief geometry increases cutting edge stability, supports long tool life, and reduces reconditioning cost by easing regrinding. With a 0.125-inch nose radius and right-hand helical flutes at a 30-degree helix angle, this tool handles both roughing and finishing passes.

This end mill is suited for CNC machining centers and manual mills where long-reach ball profiling is required. The 6-inch OAL with a 0.25-inch straight-cylindrical shank allows access into deeper cavities and complex contoured surfaces. The center-cutting design supports plunging and ramping entry, making it practical for 3D contouring and die or mold work. It is a single-end configuration intended for professional machinists running production or job-shop operations in steel and stainless applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• TiAlN PVD coating rated for steel, stainless steel, and cast iron applications
• Eccentric relief geometry extends cutting edge stability and tool life
• Center-cutting design supports plunging, ramping, and 3D contouring
• Long series length at 6 inches OAL with 1.5-inch reach length for deep-cavity access
• Right-hand cut, right-hand helix, 30-degree medium helix angle for controlled chip evacuation

Compatibility

Designed for use in CNC machining centers and conventional mills with standard straight-cylindrical 0.25-inch shank collet or end mill holders. Intended for cutting steel, stainless steel, and cast iron as stated by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank in a properly sized collet or end mill holder with sufficient clamping engagement to prevent pull-out under cutting loads. Verify runout with a dial indicator before production cuts, as runout directly affects surface finish and tool life with ball end mills.
