I use this attachment predominately in remodeling and/or repair where I need to make receptive cuts to a specific depth. An example is repairing spots of rotted wood on exterior windows (which is constant issue here on the coast). I can cut out exact sections of the existing trim without damaging surrounding area. Then make replacement "plugs" to size to fill the gap. Allows ease of cutting - especially if up on a scaffold or ladder.
