Description

Zund Milling & Router Bits R50(3910718)

Zund R50 CNC Solid Carbide Spiral Milling & Router Bit (Item No. 3910718) is an industrial-grade cutting tool optimized for processing tough, non-ferrous metals and rigid plastics on digital flatbed cutters. Unlike the 3 mm shank sizes found in the R73–R76 series, the R50 transitions to a thicker 4 mm shank and cutting diameter, providing superior core strength for high-speed cutting applications.

Performance Characteristics

The R50 features a polished single-flute design specifically engineered to counteract heat friction when cutting dense materials. Its right-hand spiral configuration generates a strong upward lifting force, which ejects metal spirals and hot plastic chips out of the channel instantly. This aggressive chip clearing prevents chip welding—a common issue where aluminum or acrylic melts and fuses back onto the cut path.

Because of its larger 4 mm profile, the tool absorbs heavy lateral forces easily, minimizing deflection and chatter during continuous, high-volume production runs.
