One of the few square cutters I own that like the others gives a very smooth cut with minimal grinding to remove machine marks. variable speed 2.25 hp (Required to work with large diameter bits at lower speeds!) Bosch router bits. It's one. Free advice!) There is a bearing that can also be replaced with aftermarket bearings if you need a smaller cutout diameter. I recently used it to trim the top of the top of the media center (photo)
