Robbjack S1-201-06 Square End Mill 3/16 in 2 Flute Carbide

Product Description

The ROBBJACK S1-201-06 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. This single-end tool features a 3/16 inch cutting diameter, a 3/8 inch length of cut, and a 2 inch overall length in a stub-length configuration. With 2 flutes and a 30-degree spiral helix, it delivers efficient chip evacuation and clean edge geometry on a range of workpiece materials. The straight cylindrical shank measures 3/16 inch in diameter, making it compatible with standard collet and end mill holder setups. It is centercutting, allowing plunge and ramp entry without a pre-drilled pilot hole. Licensed machinists and CNC operators are the primary installers of this tooling.

This end mill is suited for light milling, slotting, profiling, and contouring passes in machining centers and manual knee mills. Its stub-length body provides increased rigidity and reduced deflection in short-reach applications where tool overhang must be minimized. The right-hand cut and right-hand flute configuration follow standard industry orientation. Uncoated solid carbide at material grade C2 makes this tool appropriate for dry or flood-cooled cutting in a variety of ferrous and non-ferrous materials.

Key Features

• Solid carbide construction at material grade C2 for hardness and wear resistance
• 2-flute, 30-degree helix spiral geometry for efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Stub-length body increases rigidity and reduces deflection in short-reach cuts
• Right-hand cut and right-hand flute configuration matches standard toolholder orientation
• Uncoated finish suitable for use with or without cutting fluid

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 3/16 inch collets and end mill holders used in CNC machining centers and manual milling machines within the ROBBJACK S1-201 series.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Torque the collet nut or set screw according to the toolholder manufacturer specifications. Verify runout at the cutting diameter before commencing any cut to avoid premature tool wear or workpiece damage.
