Freud-99-320 -Vertical Raised Panel Bit. Freuds precision ground carbide bits have a grain size smaller than other grades, and titanium is added making them impervious to chemical attack. Bits are computer balanced to insure vibration-free operation at speeds that are a safe margin above the typical 22,000 RPMs of most routers. Freuds philosophy is woodworkers should expect safety, not pay for it. Over all diameter 1-1/2-inch, large radius 25/32-inch, overall length 3-3/16-inch.
