Electrocution hazards make it unwise to use corded masonry cutoff saws whenever water is present, but gasoline models come with their own shortcomings—exhaust emissions, weight, noise, and engine maintenance to mention a few.
Shown at the World of Concrete 2019, the Stihl TSA 230 Cutquik avoids both these shortcomings by using a 36-volt lithium-ion battery system.
The saw weighs just 8.6 pounds and features a quiet, brushless, high torque motor. The battery provides up to 15 minutes of cutting time.
The TSA 230 takes a 9-inch wheel and cuts to a depth of 2-3/4 inches. The belt drive is sealed for reduced maintenance and a spindle lock makes blade changes easy. With the appropriate blade it can also be used to cut rebar and metal stock.
