Expand the capability of your router with this 10 piece brass bushing set. Use your router as a precision cutting machine for duplicating patterns, cutting signs, creating dovetails, or any other project requiring template work. Unlike bearing tipped bits which can fail, this heavy duty, precision machined brass bushing set provides worry free routing. All guides protrude 0.240" for work with any template material of 1/4" thickness and larger. These guides will fit any router sub-base.
