287 Top Bearing Pattern Bit

A flush trim bit is a type of router bit used in woodworking. It is designed to trim or “flush” the edge of one material to be perfectly even with the edge of another. This is commonly used to remove excess material when working with laminates, veneers, or other materials that need to be flush with an existing
surface.The top bearing pattern on a flush trim bit refers to the bearing that is located at the top of the bit, just above the cutting edge. This bearing is used as a guide against a template or a workpiece edge to ensure that the router follows the desired pattern or profile precisely. The bearing follows the template or edge while the cutting edges of the bit trim away the excess material. Flush trim bits are available in various sizes and configurations, so the “top bearing pattern” may vary depending on the specific bit. You can find flush trim bits with different bearing patterns to suit your woodworking needs, such as top-bearing, bottom-bearing, or even double-bearing patterns. The choice of bearing pattern depends on the specific routing task and the type of template or edge you are working with.
