Bosch recently announced their new 12" dual-bevel glide miter saw. The most striking feature of the saw is the axial-glide system, replacing the traditional sliding on rails design of previous sliding miter saws. The Axial-Glide system operates by folding the articulated arm flush with the back of the saw, saving up to 12” of workspace versus a traditional sliding compound miter saw and enabling the saw to be operated with almost no clearance behind it; ideal for jobsites and cramped workshops. By removing the rail assembly and replacing it with robust cast-aluminum arms, Bosch has built a saw that remains aligned and calibrated even in harsh conditions. With 12 sealed precision ball bearings in place of the sliding-rail interface, the saw provides infinite smooth travel and better control at all miter and bevel angles for the life of the tool. As an added measure of control, a glide damper enables users to increase or decrease the glide action to meet their exact needs.
