Trimming router cutters and profiling router cutters

The following pages look at what exactly are trimming and profiling router cutters. They are guided router cutters with a bearing or pin guide they are usually used for trimming laminate or veneer so it's flush t an under surface, or for trimming a workpiece flush to a top layer, such as to a template.

They are commonly used with templates or jigs are the guide on the router cutter means there is no need for a guide bush to be used. They are excellent at trimming face sheet materials, or other profiling tasks. 

There are a few different types of trimming or profiling router cutters to choose from. Trimming router cutters typically have a guide mounted beneath their cutting edges. Profiling router cutters have the guide mounted on their shaft.

Some 90-degree double guided trimmers are overlap trimmers and have two lots of cutting edges with a bearing guide in between them. Other Professional TCT 90-dgree double-guided trimming cutters have bearing guides fitted to both the shank and end of the cutter.

One special type of trimming cutter has an angled section at the bottom of its cutting edges which is designed to cut a V-shaped groove. Bevel trimmers have angled cutting edges in order to bevel the edges of a piece of material. 

Pierce and trim cutters are most commonly used to cut laminate once it has been applied to a worktop or similar item, they're often referred to as laminate pierce and trim cutters. Above their cutting tip is a non-cutting section similar to a guide pin which allows them to be used like a regular trimming bit to cut back the excess material of a top layer (usually laminate and sometimes veneer) so that it’s flush with the material beneath.

 Other trimmer router cutters include combination trimmers, chamfer trimmers, overlap router trimmers, flush router trimmers, and profile trimmers. Some of the profilers include undercut profilers, template profilers, and profiler rebate trimmers.
