Robbjack SR-2-022 Square End Mill 0.022 in 2 Flute Carbide

Product Description

The ROBBJACK SR-2-022 is a solid carbide square end mill designed for precise milling operations in tight-tolerance applications. Part of the SR-2 series, this tool features a 0.022-inch cutting diameter with a 0.066-inch length of cut and a 1/8-inch straight cylindrical shank. The 2-flute geometry with a 30-degree spiral helix angle promotes efficient chip evacuation in small-feature milling. Built from ROBBJACK Tuffy-grade solid carbide, this uncoated end mill is centercutting capable, supporting both plunge and peripheral cuts. Overall length is 1.5 inches. Machinists and toolroom operators use this tool for micro-milling slots, pockets, and contours in ferrous and non-ferrous materials.

The SR-2-022 is suited for small-feature milling work encountered in precision machining, mold and die, medical device manufacturing, and electronics applications. Its right-hand cut and right-hand flute configuration is standard for conventional CNC machining centers and manual mills. The regular-length geometry and compact diameter make it well suited for detailed profile work where toolpath accuracy and dimensional consistency are critical.

Key Features

• 0.022-inch cutting diameter with mill diameter tolerance of plus 0.0005 / minus 0.0005 inches
• 2-flute spiral flute design at 30-degree helix angle for efficient chip removal
• Centercutting geometry allows direct plunge entry
• Tuffy-grade solid carbide construction for rigidity and wear resistance
• Right-hand cut, right-hand flute - standard CNC-compatible configuration
• Straight cylindrical shank with shank diameter tolerance of minus 0.0001 / minus 0.0002 inches

Compatibility

Designed as a standard straight-shank solid carbide square end mill compatible with 1/8-inch collets and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes should be performed with the machine in a fully stopped and locked-out state. Seat the shank fully in the collet or tool holder and torque the retention mechanism per the holder manufacturer specification. Inspect the cutting edges and shank for damage before each use. Micro-diameter end mills are brittle - avoid side-loading beyond recommended depths of cut for the diameter class.
