Robbjack SS-2-033 Square End Mill 0.033 in 2 Flute Carbide

Product Description

The ROBBJACK SS-2-033 is a solid carbide square end mill engineered for precision micro-milling applications. With a cutting diameter of 0.033 inches and a length of cut of 0.0495 inches, this tool is built for tight-tolerance work in small-feature machining. The 2-flute spiral design with a 30-degree helix angle promotes efficient chip evacuation at high spindle speeds. The 1/8-inch shank and 1.5-inch overall length make it compatible with standard collet toolholding systems. This end mill is centercutting capable, allowing plunge entry into the workpiece. Machinists and CNC operators working in job shops, prototype facilities, and production environments use this tool for fine detail work in a wide range of materials.

The SS-2-033 is suited for high-precision milling operations where small-diameter tooling is required. Its stub-length profile provides added rigidity, reducing deflection during cuts in close-tolerance features such as slots, pockets, and contours. The uncoated solid carbide construction is appropriate for applications where coating interaction with the workpiece material is a concern, or where re-sharpening is anticipated. Right-hand cut and right-hand flute orientation are standard for conventional CNC milling setups.

Key Features

• 0.033-inch cutting diameter for micro-milling and fine-detail work
• Solid carbide construction for hardness and wear resistance
• 2-flute spiral design with 30-degree helix for efficient chip evacuation
• Centercutting capable - supports plunge entry into the workpiece
• Stub-length profile reduces deflection and improves rigidity
• Uncoated finish suitable for a broad range of base materials

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 1/8-inch collet toolholding systems on CNC machining centers and manual mills.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the collet and toolholder are clean and free of debris before seating the 1/8-inch shank. At this diameter, tool runout is critical - verify runout with a dial indicator before production cuts. Follow the machine manufacturer and tooling guidelines for feeds, speeds, and depth of cut appropriate to this diameter.
