Robbjack XF-602-20-060 Corner Radius End Mill 5/8in 6 Flute

Product Description

The ROBBJACK XF-602-20-060 is a solid carbide corner radius end mill engineered for finishing operations in demanding metalworking applications. It features a 5/8-inch diameter, a 0.06-inch corner radius, and 6 helical flutes with a high-helix, close-pitch configuration that promotes smooth chip evacuation and consistent surface finish. The tool carries an AlTiN (aluminum titanium nitride) PVD coating applied for elevated heat resistance and extended tool life at high cutting speeds. With a 1-1/4-inch length of cut and 3-1/2-inch overall length, this end mill is suited for profile milling, contouring, and finishing passes where edge integrity and corner geometry accuracy are critical. It is center-cutting and right-hand cutting with a Weldon flat shank for positive drive retention in compatible toolholders.

This end mill is designed for finishing-grade material removal on ferrous and exotic workpiece materials. Primary material applications include steel, stainless steel, cast iron, superalloys, and titanium - material classification codes P, M, K, and S. It is well suited for CNC vertical machining centers and milling operations where tight tolerances and fine surface finishes are required in tool and die, aerospace, and general precision machining environments.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in high-hardness materials
• AlTiN PVD coating for enhanced thermal protection and extended tool life
• 0.06-inch corner radius reduces stress concentration and improves corner durability
• 6-flute, high-helix helical geometry optimized for finishing passes and fine surface finish
• Center-cutting design allows direct plunge entry
• Weldon flat shank provides positive drive engagement in standard toolholders
• Right-hand flute direction and right-hand cutting for standard CNC spindle compatibility

Compatibility

Designed for use with standard toolholders accepting a 5/8-inch Weldon flat shank. Part of the ROBBJACK XF Series, intended for finishing applications in steel, stainless steel, cast iron, superalloys, and titanium workpieces.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Confirm toolholder bore and set-screw alignment with the Weldon flat before tightening. Power down and lock out the spindle drive before inserting or removing the end mill. Verify runout at the cutting diameter after seating to ensure dimensional accuracy within the specified mill diameter tolerance of 0.0010 to 0.0020 inches.
