    Router Requirements

    Handheld Router

    What Router Should I Use? The B975 is shipped with a 1/2" shank router bit. Leigh recommends a midsize router, from 1-1/2 to 2-1/4 HP (9-13 amps) with a 1/2" collet. This size provides great power to weight ratio. Fixed base routers are ideal because they have a lower center of gravity with handles mounted to the router base rather than the motor, as with plunge routers. However, if you are proficient with the use of a plunge router, it works just as well. When buying a router, also consider ergonomics, switch location, a good plunge mechanism and easy, accurate adjustment of bit height.

    Adaptors for your Router The B975 requires a router fitted with the Leigh e10 guide bushing. Leigh offers a range of guide bushing adaptors to fit most common routers. Learn more >

    Router Table

    Router tables are typically used with a bearing or fence, however, the Leigh B975 is guided around a guide bushing mounted in the router table. Leigh eBush guide bushings are designed to the decades-old Porter Cable/Black & Decker industry standard. Therefore, you will need an insert ring to fit the included eBush to your router table or router plate. See specifications below.
