Robbjack SR-2-015 Square End Mill 0.015 in 2 Flute Carbide

Product Description

The ROBBJACK SR-2-015 is a square end mill designed for precision micro-machining in a wide range of metalworking and manufacturing applications. Built from solid carbide in RobbJack's Tuffy material grade, it delivers the rigidity and edge retention needed at extremely small diameters. The cutting diameter measures 0.015 inches with a 0.045-inch length of cut and a 1/8-inch straight-cylindrical shank. Overall length is 1.5 inches. The two-flute, right-hand spiral design at a 30-degree helix angle promotes efficient chip evacuation in tight geometries. This tool is uncoated and centercutting, making it capable of plunge entry as well as peripheral and slot milling.

The SR-2-015 is suited for mold and die work, aerospace components, medical device machining, and any application requiring fine detail cuts in ferrous and non-ferrous materials. Its regular-length geometry fits standard micro-machining setups on CNC machining centers and high-speed spindles. The Series SR-2 designation indicates a two-flute short-flute carbide configuration optimized for small-diameter work where tool deflection and runout control are critical.

Key Features

• 0.015-inch cutting diameter with tight mill diameter tolerance of plus 0.0005 and minus 0.0005 inches for consistent sizing
• Solid carbide Tuffy grade construction for high rigidity and wear resistance at micro scale
• Two-flute spiral design with 30-degree helix angle for efficient chip clearance
• Centercutting geometry allows plunge milling as well as slot and profile cuts
• Right-hand cut and right-hand flute orientation for standard CNC spindle use
• Straight-cylindrical 1/8-inch shank fits common micro-tool collet systems

Compatibility

Designed as a standard micro end mill replacement for CNC machining centers and high-speed spindle setups accepting a 1/8-inch straight-cylindrical shank in the ROBBJACK SR-2 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and locked out before changing tooling. Use a precision collet or shrink-fit holder sized for the 1/8-inch shank to minimize runout, which is especially critical at 0.015-inch cutting diameters. Verify tool projection and runout with a dial indicator before initiating any cutting cycle.
