The Stone Mountain Offset Router Collet Wrench makes changing the router bits on a table mounted router much easier and quicker. The unique bent wrench design allows you to place the wrench right on the collet where it needs to be without having to reach underneath the table top. The wrench is made from Heavy Duty Plated Steel for extra durability. The handle is fitted with a comfortable grip and has a convenient hanging hole on the wrench for storage. There are 4 different size wrenches to choose from. It is recommended that you measure the size of your router collet before making your purchasing decision. Please note that some routers may require two wrenches to work properly
