CS Unitec
The Airbor AB-4300-2R magnetic drill from CS Unitec has a 1.6-hp air motor, powered completely by compressed air, allowing it to be used around water without fear of shock or blown circuitry. The drill is designed for heavy industrial use, and its air-powered magnet has a holding strength of 1,600 pounds. Because it has an extra-long 10¼-inch stroke, this drill can be used with a geared chuck adapter and a solid twist drill. When converted to a drill press, it can drill up to ½-inch diameter holes in structural steel and other applications.

General Equipment
The MDF35 long reach air tool is designed for a variety of applications, including the removal of floor tile, mastics, adhesives and general concrete as well as stripping material buildups. The MDF35 utilizes an internal valving mechanism that allows the piston to deliver increased kinetic energy per blow over competitive products. Weighing 18.5 pounds and equipped with a 60-inch whip hose, the MDF 35 requires a flow rate of 11 cfm at 90 psi and produces 3,100 blows per minute. The air tool also features an ergonomically designed throttle valve with protective enclosure and a heavy-duty tool-changing device intended to minimize the harmful effects of concrete dust and dirt accumulation.

Sullair
The MPB-90 AFS paving breaker from Sullair is ergonomically designed with a hinged anti-vibration handle that reduces vibration by as much as 60 percent to lessen operator fatigue without any loss of power. Vibrations are reduced by crossed handles that swivel on two pins located on either side of the breaker head. Helical springs prevent direct contact between the handles and the body of the breaker, allowing the springs to act as effective isolators. Other features include handle guards to prevent operator hand contact with the flex joints. A unique super-silent muffler reduces noise levels by 6 dBA and prevents the tool from freezing. Its direct impact design delivers more impact energy pound for pound than conventional breakers, according to the company.
