Robbjack SR-2-044 Square End Mill 0.044 in 2 Flute Carbide

Product Description

The ROBBJACK SR-2-044 is a solid carbide square end mill engineered for precision milling in tight-tolerance applications. Part of the SR-2 series, this two-flute tool features a 0.044-inch cutting diameter and a 0.132-inch length of cut, making it well suited for small-feature work in molds, dies, and detailed components. The 1/8-inch straight cylindrical shank fits standard collet systems. At 1.5 inches overall length, this is a compact, rigid tool built for accuracy in materials where carbide grades such as Tuffy deliver consistent performance. Licensed machinists and CNC operators rely on tools like this for micro-milling and finishing passes where dimensional control is critical.

This end mill is designed for use in CNC machining centers and manual mills running small-diameter work. It is well matched to applications in tool and die, medical component manufacturing, electronics, and aerospace where small features and tight tolerances are required. The centercutting geometry allows for plunge entry as well as conventional and climb milling passes. Right-hand cut and right-hand flute orientation are standard for most spindle setups.

Key Features

• 0.044-inch cutting diameter with a mill diameter tolerance of plus 0.0005 / minus 0.0005 inches for precise fitment
• Solid carbide construction in Tuffy material grade for rigidity and wear resistance in demanding cuts
• Two-flute spiral design with 30-degree helix angle promotes chip evacuation in small-diameter milling
• Centercutting capability allows plunge milling without a pre-drilled entry point
• Right-hand cut and right-hand flute for compatibility with standard CNC and manual spindle configurations
• Straight cylindrical 1/8-inch shank with shank diameter tolerance of minus 0.0001 / minus 0.0002 inches

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills accepting a 1/8-inch straight cylindrical shank collet or chuck.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before installing or removing the tool. Seat the shank fully and evenly in the collet to the recommended engagement depth before tightening to prevent runout. Inspect the cutting edges under magnification before use, as carbide micro-diameter tools can sustain edge damage during handling.
