Robbjack SS-2-024 Square End Mill 0.024 in 2 Flute Carbide

Product Description

The ROBBJACK SS-2-024 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 0.024-inch cutting diameter and a 0.036-inch length of cut, this stub-length tool is built for shallow slotting, profiling, and finishing passes where rigidity and accuracy are critical. The 2-flute geometry and 30-degree helix angle promote efficient chip evacuation in a compact form factor. At 1.5 inches overall length with a 0.125-inch straight-cylindrical shank, it mounts in standard collet chucks and tool holders common in CNC machining centers and manual mills. The uncoated Tuffy-grade carbide substrate suits a range of workpiece materials.

This end mill is suited for light-duty milling operations requiring high precision at very small diameters. Typical applications include detail work in mold and die, micro-slot milling, engraving, and finish profiling on ferrous and non-ferrous materials. The centercutting design allows plunge entry, expanding its use in contouring and pocket milling routines. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC setups.

Key Features

• 0.024-inch cutting diameter with a tight mill diameter tolerance of plus or minus 0.0005 inches
• Solid carbide Tuffy-grade construction for rigidity and wear resistance at micro diameters
• 2-flute, spiral flute geometry with a 30-degree helix angle for efficient chip flow
• Centercutting design permits direct plunge entry into the workpiece
• Stub length (0.036-inch LOC) maximizes tool stiffness and minimizes deflection
• Straight-cylindrical shank at 0.125 inches fits standard collet systems

Compatibility

Designed as an OEM-style replacement or direct-use tool for CNC machining centers and manual mills accepting a 0.125-inch straight-cylindrical shank, within the ROBBJACK SS-2 series of solid carbide square end mills.

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. Secure the shank in a precision collet or end mill holder and verify runout before beginning the cut. Avoid excessive overhang beyond the shank engagement length to prevent deflection at this small diameter. Cutting parameters should be selected based on workpiece material, machine rigidity, and the manufacturer's recommended speeds and feeds for micro-diameter carbide tooling.
