About Router Bits

Straight router bits are one of the most overlooked styles of all router bits being used today. One of the most common, straight router bits have dozens of subcategories with hundreds of uses. CNC Router Bits are straight router bits used in CNC machines. They have their own classification because these router bits are specially designed for fast moving, very high RPM machines to move them constantly with very little time to cool off. This means CNC router bits have to have a durable cutting edge, be able to remove the excess material efficiently, and be able to work with the router moving at fairly quick directional speed. Spiral router bits are designed with several different advantage points. Spiral router bits can force the excess material they cut down (called downcut router bits) away from the cutting path, or up (upcut router bits) and out of the way. Spiral router bits can also be designed to assist in holding the material while the router bits job is being performed. Many CNC router bits, including spiral router bits, are made of solid carbide. Solid carbide router bits, while more expensive in many cases, help to meet he challenge and demands of sever applications placed upon straight router bits.

Other well known router bits include laminate trim router bits. As the name implies, these router bits are designed to trim a material that is overhanging another piece of material you do not wish to cut. Laminate trim router bits typically come equipped with a bearing to help flush the cutting surface against the material to be cut without damaging the underlying material. Edge beading router bits provide a decorative bead profile. These router bits are commonly used in making furniture pieces or used as molding router bits. Chamfer router bits, usually in a 45° angle, are specialty router bits. Also used in furniture applications, chamfer router bits provide a less harsh look to the corners of a piece where roundover router bits are not available or not desired. Cove router bits and bullnose router bits are complete opposites of each other, but often used in similar applications, the edge of a countertop or to decorate a table edge. Cove router bits offer a concave or sunken in profile, while bullnose router bits offer a half circle or half rounded profile.
