Campbell Hausfield has introduced a 1/2 inch twin hammer impact wrench to its Extreme-Duty line of air tools. Designed for professional automotive and industrial applications, the twin hammer impact wrench, model PL2502, was engineered for quick removal and replacement of fasteners, tire rotation and engine rebuilds. This tool is capable of producing the highest level of power at 425 foot-pounds of torque. It produces 1,200 impacts per minute. Other features include a 1/2 inch square drive and an all-in-one adjustable power regulator that controls speed as well as forward and reverse action. The new Craftsman impact wrench features handle exhaust that routes exhaust away from both the user and the work surface. Provides torque range from 25 to 200 ft/lbs. with maximum torque of .260 ft./lbs. in reverse. It delivers 1500 blows per minute, yet weighs only 2.5 pounds.

As the marketing manager for a power tool company, I''m often asked about the difference between hammer drills and rotary hammers. Buyers want to know why there''s such a price difference between the two, and which tool is best suited for specific applications.I advise users to answer four questions before making the choice: What material will you usually be drilling? How large will the holes be? Will you be drilling an occasional hole or for extended periods? Finally, will you only be drilling, or would it also be useful to be able to use the tool in chipping, or hammer-only, mode?

"The Cat engine, combined with the new anti-stall hydraulic drive system, gives the PB50 and PB65 increased performance and makes it easier for the new operator to drive like a pro in rough terrain."Both of the Piggy Back machines are highly maneuverable--turning radius is 78 in. and gradability is 50 percent--and can reach speeds of 8 mph. Braking is dynamic and to hold the machine when parked, the front wheels are also equipped with Poclain brakes.The PB50 offers a standard lift height of 86 in. with optional lift heights as high as 165 in. available. Dimensions of the 5890 lb. machine are 96 in. high, 100 in. wide and 136 in. long. The PB65 weighs 7000 lb., and shares the same height and width dimensions, but is 5 in. longer than the smaller machine. Both have a ground clearance of 15 in.
