A long-stroke piston gives the new Hilti DS-HS hand-held gas concrete saw a flattened torque curve to help maintain constant blade speed under load. This results in less wear and tear on the blade and saw and less fatigue for the operator. Sealed triple filtration with a metal main filter keeps the motor clean for longer life and less downtime. The solid steel flanges can be reversed for a 1-inch or 20-millimeter arbor and the guard features a large lock knob for easy adjustment. The DS-HS also has a digital coil for easier starts and less flooding.
