Robbjack XG-402-32 Corner Radius End Mill 1 in 4 Flute Altin

Product Description

The ROBBJACK XG-402-32 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. It features a 1-inch cutting diameter, a 2-inch length of cut (LOC), and a corner radius range of 0.028 to 0.030 inches. The four-flute, right-hand cutting geometry is paired with an AlTiN coating for extended tool life in abrasive and high-temperature cutting environments. With a 5-inch overall length (OAL) and a 1-inch shank diameter, this end mill is sized for rigid setups on vertical and horizontal machining centers. It is centercutting capable, allowing plunge entry where required.

This end mill is suited for finish milling and semi-finish profiling operations on ferrous metals, hardened steels, and high-temperature alloys. The fine pitch flute spacing and right-hand helix promote smooth chip evacuation and surface finish control. It is commonly applied in die and mold work, aerospace component machining, and general precision machining where corner geometry must be held to tight tolerances. A licensed machinist or CNC setup technician handles installation and toolpath programming for this tool type.

Key Features

• 1-inch cutting diameter with 2-inch LOC for deep slot and profile work
• Corner radius range of 0.028 to 0.030 inches for controlled edge blending
• AlTiN coating for heat resistance and extended tool life in ferrous materials
• Four-flute, right-hand cut and right-hand helix geometry
• Centercutting design permits plunge milling entry
• Fine pitch flute configuration for improved surface finish
• Solid carbide construction for rigidity and wear resistance

Compatibility

Designed for use in standard 1-inch collet or end mill holder tooling systems on CNC vertical and horizontal machining centers. Part of the ROBBJACK XG-402 series.

Installation Notes

Installation is performed by a qualified machinist or CNC technician. The shank must be seated fully and evenly in a clean, undamaged collet or end mill holder before torquing the retention nut to the holder specification. Inspect the tool shank and holder bore for chips or runout before use. Follow machine-specific RPM and feed rate guidelines for the workpiece material and do not exceed the tool's rated depth of cut.
