Whiteside has been ranked #1 numerous times and by several renowned magazines including Fine Woodworking for making their router bits some of the best carbide router bits available. Made in USA, the quality of these router bits is unsurpassed and the brand is well known throughout the woodworking industry.

Unlike an upcut spiral router bit which throws chips out directly, a downcut router bit requires a relatively slower cut speed because it needs more time to remove those chips. If a downcut bit works at a very fast speed, a build-up of wood chips inside the groove may cause overheating or even break the bit.
