Robbjack SS-2-008 Square End Mill 0.008 in 2 Flute Carbide

Product Description

The ROBBJACK SS-2-008 is a solid carbide square end mill designed for precision micro-milling applications. With a cutting diameter of 0.008 inches and a 1/64-inch length of cut, this tool is built for fine detail work in tight geometries. The 30-degree helix spiral flute geometry promotes chip evacuation while maintaining edge stability at small diameters. A 1/8-inch shank provides secure tool holding in standard collet systems. This end mill is uncoated and centercutting, making it capable of plunge entry. It is installed and used by machinists and CNC tool operators working in precision manufacturing environments.

This end mill is suited for micro-scale milling operations in materials where tight tolerances and fine surface finishes are required. The stub-length configuration and 1-1/2-inch overall length make it appropriate for use in CNC machining centers where rigidity and minimal runout are critical. It is typically used in aerospace, medical device, electronics, and mold-and-die applications where extremely small cutter diameters are necessary. The right-hand cut and right-hand flute orientation follow standard CNC mill conventions.

Key Features

• 0.008-inch cutting diameter for micro-milling and fine detail work
• Solid carbide construction for rigidity and wear resistance at small diameters
• 30-degree helix spiral flute for effective chip evacuation
• Centercutting design allows plunge entry into workpiece
• Right-hand cut, right-hand flute - compatible with standard CNC spindle direction
• Stub length type for maximum tool rigidity

Compatibility

Designed for use in CNC machining centers and manual mills with a 1/8-inch collet or tool holder. Part of the ROBBJACK SS-2 series of solid carbide square end mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a calibrated collet or end mill holder sized for a 1/8-inch shank and verify runout with a dial indicator before running production. At 0.008-inch diameter, even minor runout or excessive feed rates can cause tool breakage - follow manufacturer feed and speed recommendations for the workpiece material.
