The Bosch-exclusive Axial-Glide offers wider cross-cuts, enhanced alignment and smooth glide for the life of the tool. The Bosch miter saw’s 15 Amp motor delivers no-load speeds of 3,800 RPM for quick, accurate cuts in many materials. For added convenience and versatility, the saw is compatible with a variety of 12 In. blades and it has a clear lower guard to provide unobstructed cut-line visibility. The GCM12SD provides easy adjustments with upfront bevel and miter controls and detents at common angles. The saw’s all-metal bevel lock lever and range selector are located up front to make bevel adjustments easy.
