The Barre TYPE-D tools provide the maximum power per size ratio available anywhere. These tools are the most aggressive and are generally reserved for shaping the hardest types of stone or heavy material removal. By using a longer stroke than our other pneumatic tools, the TYPE-D strikes a harder blow over the full power range. The simple design and rugged construction deliver reliable and economical operation on the most demanding work. The 1in and 1-1/4in sizes are suitable for larger roughing applications and offer a shaped fingertip for greater comfort and control during extended use. The 1/2in and 3/4in sizes are perfect for finer jobs where detail and precision are required.
