| Six models complete the Bosch grinder line, which has been designed to meet and exceed the needs of professionals in the metal and concrete construction industries, according to the manufacturer. The model 1873-8 is Bosch’s first 7-inch 8,500 RPM and 3-HP large angle grinder to be offered in North America. The grinder’s speed optimizes the removal rate of any 7-inch wheel accessory, the manufacturer says. The 1873-6 is a 3-HP 7-inch 6,000 RPM grinder, an industry standard. For those looking for larger diameter wheels, both the 1893-6 and 1894-6 tools offer 9-inch wheels. The former, at 6,000 RPM and 3-HP offers the best power-to-weight ratio available, while the latter is the champ at 4.5-HP and barely over 13-pounds. The 1894-6’s rotating D-handle gives users the ability to position the handle for optimal comfort and control in any job. Rounding out the line are 7- and 9-inch large angle sanders — 1853-5 and 1853-6, at 5,000 and 6,000 RPM, respectively. Across the line, enhancements in usability and durability include the addition of a tool-free adjustable guard and a metal gear cover for working in the most demanding applications, Broan says. Epoxy coated field windings provide the ultimate protection against abrasive dust and debris while precision spiral bevel gears offer quality engineering and construction for smooth power transmission. Each unit is also AC/DC compatible for use with welders or generators. This feature is solely for educational and informational purposes.
