The new Hilti Cordless 22-Volt tube belt sander with electronic speed control can be used for grinding and finishing tubular stainless steel, aluminum, copper, brass and titanium. 5 speeds so you can use higher speeds to remove material very quickly, while the lower speeds help you to craft a perfect polished finish on stainless steel. Upgraded ergonomics with lock-on switch - this cordless burnisher fits firmly in your grip, for more comfortable handling and precise control. Use for rough grinding - efficiently removing welding seams, burrs, rust, coatings or tarnish on larger metal surfaces.
