Downcut Roughing Router Bits - 3 Flute

Roughing router bits remove excess material during nesting applications, this allows for a finishing cutter to remove the remaining onion skin leaving a superb finish.

Down cut refers to the direction of the flute. As the router bit grooves, slots and cuts the chips are forced downwards. Therefore, the best finish is on the topside of the cut part. The downwards chip flow also assists in holding the material in place. However, feed speeds should be reduced due to the increase of pressure on the tool.

Three flute router bits have a smooth cutting action and a greater finish in harder materials. Three flute router bits last longer, run faster feed rates and are less susceptible to breaks than one and two flute router bits.
