Bosch
Robert Bosch Tool Corp. recently unveiled the new 1775E, a 5-inch grinder, designed specifically for professional tuckpointers. Developed specifically for tuckpointing applications, Bosch combined a multi-positioning head with its exclusive dust extraction system to provide debris management. Better accuracy and control are achieved by viewing the work area through the newly designed guard and the enlarged view window. Weighing only 5.6 pounds, the 8.5 amp, 11,000 rpm motor constantly maintains speed under load, ensuring an even removal rate.
Erich Stefans, general field superintendent for Berglund Construction, Chicago, worked with Bosch to find a grinder that particularly met the company's needs. The product allows you to adjust the depth, and provides a window to see the blade while it's cutting,” Stefan said. “Plus, the Bosch tools outlast anything we've ever dealt with,” he adds. And because the guard can be used on other grinders, Stefans plans to purchase more from the distributor, The Glenrock Co., soon.
