る。In the present invention, in a grinder device operated by air pressure, a dust collection bag is connected to its exhaust port via a duct hose, and the dust receptacle provided around the grinding wheel is fully connected to the duct hose. Regarding the characteristic grinder device,
F outside air gathers in the high-speed air discharged from the nozzle outlet! The dust is sucked into the exhaust duct hose from the dust collection hose from the dust collector, is generated from the grinding wheel, is scattered to the dust collection receiver, and is collected together with the outside air through the dust collection hose and the exhaust duct hose into the dust collection bag. The grinder folds also reduce the noise generated by the grinder! It can be applied to a dust-absorbing, noise-reducing hand grinder.
