We carry a large range of powered mitre saws from SIP and GMC. The saws that we sell all mitre left and right +-45 degrees. All of them have slides to lengthen their cross cut capacity, one has a single square slide bar and the rest are dual slide mitre saws. Some saws are single bevel with the larger saws being dual bevel compound mitre saws. The dual bevel allows for cutting of both right and left compound mitre cuts without having to turn over the workpiece. Some of the saws have where noted in their product info laser guide beams for easier alignment of the timber. Take a look at the SIP Ultimate for a saw that can cut wood, steel, copper or plastic.
