Whiteside RU4950 Standard Upcut Spiral Router Bit Solid Carbide 7/16" Cutting Diameter 1-1/4" Cut Length 1/2" Shank 2 Flute

I have over 40 years of woodworking experience and have used bits from many different manufacturers. None compare to Whiteside for bit to bit precision, clean cutting, rapid feed rates, heat dissipation and bit life. You folks make the finest router bits I have ever used. Nothin' cuts through a nail you left behind like a Whiteside.
