Freud 22-122 1/2-Inch Diameter 8-Degree Dovetail Router Bit 1/4-Inch Shank
Freud's precision ground carbide bits have a grain size smaller than other grades, and titanium is added making them impervious to chemical attack. Promoting safer woodworking is the reason Freud made a commitment to develop anti-kickback router bits. Bits are computer balanced to insure vibration-free operation at speeds that are a safe margin above the typical 22,000 rpm of most routers. Freud's philosophy is woodworkers should expect safety, not pay for it.  Overall diameter 1/2-inch,  angle 8-degrees, shank diameter 1/4-inch.
