The Granberg G555B Edging Mill is a chainsaw attachment for vertical cuts: squaring logs into beams for cabins and other buildings, edging slabs and cutting dimensional lumber. It used to be called the Mini Mill.

Pressure bolts clamp it to the chainsaw bar, and it rides along the included V-rail to keep the cut straight. It fits chainsaws with 16 to 36 in bars and 50 to 70 cc or more. The bar must be solid steel, not laminated; laminated bars won't work with it, so check with your bar's maker before you order. It's built of aircraft aluminum and zinc-plated steel and comes with 12 ft of V-rail cutting guide (0590F), wood screws (0567F) and forming nails (0587F). It works best with Granberg ripping chain, and the size of beam or board you can cut depends on your bar length.

It's one of Pat's all-time favorite tools for milling your own lumber in the back yard.

Elof Granberg founded Granberg International and began making the File-N-Joint more than 50 years ago. The company is based in Vallejo, California, and the G555B is made in the USA.
