Robbjack SS-2-050 Square End Mill 3/64 in 2 Flute Carbide

Product Description

The ROBBJACK SS-2-050 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. Part of the SS-2 series, this stub-length, two-flute end mill has a 3/64-inch (0.0500-inch) cutting diameter and a 0.075-inch length of cut. It features a right-hand cut with right-hand spiral flutes at a 30-degree helix angle, and its centercutting geometry allows plunge entry into the workpiece. The straight cylindrical shank measures 1/8 inch in diameter. This tool is used by machinists and toolroom professionals for slotting, profiling, and detail work in small-scale features.

The SS-2-050 is suited for use in CNC machining centers and manual mills where small-diameter, high-precision cutting is required. Its stub-length design provides added rigidity, reducing deflection during cuts in ferrous and non-ferrous materials. The uncoated solid carbide construction in ROBBJACK Tuffy material grade makes it appropriate for shops running aluminum, brass, steel, and similar materials where a general-purpose carbide tool is specified. Overall length is 1.5 inches, keeping the tool compact and stiff in the spindle.

Key Features

• 3/64-inch (0.0500-inch) cutting diameter with plus/minus 0.0005-inch diameter tolerance
• Solid carbide construction, ROBBJACK Tuffy material grade
• 2-flute, spiral flute geometry with 30-degree helix angle
• Centercutting design allows direct plunge entry
• Right-hand cut and right-hand flute direction
• Stub length for increased rigidity and reduced deflection

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for 1/8-inch straight shank collets and tool holders used in standard CNC and manual milling setups requiring a 3/64-inch square end mill.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the 1/8-inch straight shank fully and evenly in the collet or end mill holder, and torque the retention mechanism per the tool holder manufacturer specification. Inspect the cutting edge under magnification before use, as solid carbide tools at this diameter are brittle and sensitive to improper handling.
