Kennametal 5607204 Ball End Mill 0.375 in 6 Flute Carbide

Product Description

The KENNAMETAL 5607204 is a solid carbide ball end mill from the HARVI III UJBE series, designed for high-performance milling in demanding materials including steel, stainless steel, high-temperature alloys, and hardened materials. With a 0.375-inch mill diameter, 6-flute geometry, and a 38-degree medium helix angle, this tool is built for both roughing and finishing operations in a single setup. The AlTiN PVD coating provides thermal resistance and extended tool life at elevated cutting speeds. Unequal flute spacing suppresses chatter for stable, consistent material removal across a range of machining conditions.

This end mill is suited for CNC machining centers in job shops, production facilities, and aerospace or medical manufacturing environments where tight tolerances and surface finish matter. The variable index geometry makes it effective in side milling, profiling, contouring, and slotting operations on ISO material groups P, M, S, and H. The single-end, straight-cylindrical shank design provides direct compatibility with standard collet and end mill holder tooling systems. It is center-cutting, enabling plunge and ramp entry without a pilot hole.

Key Features

• 6-flute solid carbide construction for rigidity and high metal removal rates
• AlTiN PVD coating rated for steel, stainless steel, high-temp alloys, and hardened materials
• 38-degree medium helix angle balances cutting efficiency and edge strength
• Variable index flute spacing reduces chatter and vibration during aggressive cuts
• Center-cutting geometry allows direct plunge and ramp entry
• Right-hand cut, right-hand flute direction with straight-cylindrical shank for standard toolholding

Compatibility

Part of the KENNAMETAL HARVI III UJBE series. Designed for use in CNC milling applications on ISO P, M, S, and H workpiece material groups including steel, stainless steel, high-temperature alloys, and hardened materials. Manufacturer catalog number UJBE0375J6B.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Secure the straight-cylindrical shank in a properly sized collet chuck or end mill holder and verify runout before cutting. Confirm spindle speed, feed rate, and depth of cut are set per the tool manufacturer cutting data for the specific workpiece material before engaging the cut. Do not exceed the rated depth of cut or operate with a damaged or worn cutting edge.
