The TSA 230 Cutquik cutoff machine from Stihl can cut stone, pipes, rebar and tile. Powered by a 36-volt lithium-ion battery, the machine features zero-exhaust emissions, which allows users to cut indoors and on other job sites where traditional gasoline-powered cutoff machines are not permitted or ideal. The onboard water connection and control helps suppress dust when wet cutting concrete, and an available depth guide with vacuum adapter enables dry cutting in dust-sensitive areas when water cannot be used. 800/467-8445; www.stihlusa.com.
