- For coarse grinding work with a high stock removal rate and a long tool life. - Abrasive: Zirconia alumina Z. - Recommendations for use: Use powerful angle grinders in the case of a higher contact pressure.
- PFG Expansion Bushings Simple; - Material: steel; - 4-way extra wide expansion for great performance also in lower quality base materials found in many old constructions. Good tolerance for variation in drill hole size.
- High volumetric efficiency. - High ventilation system for total transmission protection. - Special stainless steel valves. - Higher ventilation for high temperature areas.
