Router bits come in various different shapes and sizes. The most common cutters are those with 1/2" and 1/4" shank. Majority of modern routers come supplied with 1/2" and 1/4" clamping collet to accept either size bits. We advise to use 1/2" shank cutters whenever possible as they provide better stability with less vibration, and they typically produce a smoother cut and have longer cutter life. Different job requires different type of router cutter most popular ones are: straight bits for grooves and dados, rebeting bits to cut a shoulder in the edge of the workpiece, flush trim bits, chamfer edge bits and edge forming bits. Good router bit should have a thick carbide blade/s so can be regrinded when blunt. High quality bits will incorporate a design that minimizes the risk of workpiece kickback. These anti-kickback bits have more body mass, and their enlarged bodies prevent the bits from biting too deeply and catching on the material. The greater body mass also helps to dissipate heat and keep the bits sharp longer. Rebate cutters can often be purchased with bearings of different diameters that allow a single bit to produce rabbets of different sizes.
