Kennametal 4048724 Square End Mill 0.5in 5 Flute Altin Carbide

Product Description

The KENNAMETAL 4048724 is a solid carbide square end mill designed for high-performance metal removal in demanding machining applications. Measuring 0.5 inches in diameter with a 1.25-inch length of cut and a 3-inch overall length, this single-end tool features five flutes with a variable index geometry and an AlTiN coating for extended tool life at elevated temperatures. The 0.5-inch shank diameter provides rigid setup in standard collet chucks and end mill holders. It is installed and operated by machinists and CNC programmers in job shops, production machining facilities, and tool rooms.

This end mill is suited for milling steel, stainless steel, cast iron, and hardened materials in both roughing and finishing passes where a square shoulder profile is required. The spiral flute design and 38-degree helix angle promote efficient chip evacuation and reduce cutting forces. The variable index spacing helps suppress chatter in side milling and slotting operations. It is well matched to vertical machining centers and CNC mills running moderate to high spindle speeds with proper coolant strategy.

Key Features

• AlTiN coating provides oxidation resistance and hardness retention at high cutting temperatures
• Variable index flute spacing reduces harmonic vibration and chatter during cut
• 38-degree helix angle promotes smooth chip flow and reduced axial cutting force
• Solid carbide construction in material grade KCPM15 for rigidity and wear resistance
• Right-hand cut and right-hand flute configuration for standard CNC spindle use
• Single-end design compatible with standard 0.5-inch collet and end mill holder systems

Compatibility

Designed for use in applications machining steel, stainless steel, cast iron, and hardened materials. Part of the KENNAMETAL UCDE series. Fits any machine tool spindle or holder accepting a 0.5-inch straight shank end mill.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before installing or removing the tool. Seat the shank fully in the holder and torque the collet nut or set screw per the tool holder manufacturer specification. Confirm runout with a dial indicator before cutting; excessive runout accelerates wear and reduces surface finish quality.
