Modern windows are almost exclusively closed and opened with locking hardware made of metal, known as edge gears. They are inserted into milled grooves, which have two different depths, in windows (and doors) made of solid wood and glued wood. These grooves are cut with step cutters, which we offer here in shank length 8 mm. Please note that these cutters should be used either stationary on the router table or with a router with the aid of a suitable guide.
