Robbjack C8-201-04 Square End Mill 1/8 in 2 Flute Carbide

Product Description

The ROBBJACK C8-201-04 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. Built to Series C8-201 specifications, it features a 1/8 inch cutting diameter, a 1/4 inch length of cut, and a 2 inch overall length in a stub-length configuration. The 30-degree spiral flute geometry and right-hand cut with right-hand flute direction support efficient chip evacuation in a wide range of materials. Centercutting capability allows plunge entry directly into the workpiece. Typically installed and operated by machinists and CNC programmers working in job shops, production facilities, and tool rooms.

This end mill is suited for light finishing passes and slotting operations where a small-diameter, rigid tool is required. The stub-length profile reduces deflection, making it appropriate for applications demanding tight tolerances in ferrous and non-ferrous materials. The uncoated solid carbide construction at material grade C2 provides hardness and wear resistance in general-purpose cutting applications. The straight cylindrical shank is compatible with standard collet chucks and end mill holders accepting a 1/4 inch shank diameter.

Key Features

• Solid carbide construction at material grade C2 for hardness and wear resistance
• 1/8 inch cutting diameter with 1/4 inch length of cut for small-feature machining
• 30-degree helix angle spiral flute for efficient chip flow
• Centercutting design allows direct plunge entry into the workpiece
• Stub-length overall length of 2 inches minimizes deflection under load
• Uncoated finish suitable for general-purpose ferrous and non-ferrous applications

Compatibility

Designed as an OEM-style replacement and standard cutting tool for use in collet chucks or end mill holders with a 1/4 inch bore, compatible with CNC machining centers and manual mills accepting straight cylindrical shanks.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is locked out before tool changes. Seat the shank fully into the collet or end mill holder and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing cuts to avoid premature tool wear or breakage on small-diameter carbide tooling.
