Robbjack SS-2-052 Square End Mill 0.052 in 2 Flute Carbide

Product Description

The ROBBJACK SS-2-052 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 0.052-inch cutting diameter and a 2-flute configuration, this stub-length tool delivers clean square-shoulder cuts and slot milling in small-feature work. The 30-degree helix spiral flute geometry promotes efficient chip evacuation while maintaining edge stability in hard and abrasive materials. Centercutting capability allows direct plunge entry without pre-drilling. The uncoated Tuffy-grade carbide substrate is suited to dry or minimally lubricated cutting conditions where coating adhesion or chemical reactivity is a concern.

This end mill is built for precision machining operations where small diameters and close tolerances are required. Typical applications include mold and die work, micro-slot milling, engraving, and fine-feature profiling on CNC machining centers or manual mills. The stub length-of-cut format provides added rigidity at the small diameter, reducing deflection during aggressive passes. Right-hand cut and right-hand flute orientation follow standard CNC tooling conventions. The 1/8-inch straight cylindrical shank fits standard collets and tool holders common in production and toolroom environments.

Key Features

• 0.052-inch cutting diameter with tight tolerance of plus or minus 0.0005 inches for precise feature control
• 2-flute solid carbide construction in Tuffy material grade for strength at small diameters
• 30-degree helix spiral flute promotes chip evacuation and smooth cutting action
• Centercutting design allows direct plunge milling without pilot hole
• Stub length-of-cut format maximizes rigidity and minimizes deflection
• Uncoated finish suitable for applications where an uncoated carbide substrate is preferred

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC machining centers and manual mills accepting a 1/8-inch straight cylindrical shank collet or tool holder.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Ensure the collet and tool holder are clean and free of chips before seating the shank. At this diameter, runout control is critical - verify collet concentricity before cutting. Follow the tooling manufacturer's recommended speeds and feeds for carbide at the specified diameter and material grade.
