Straight die grinder for heavy-duty material removal
The Dynabrade 47202 is a composite straight die grinder built for heavy-duty grinding, deburring and finishing on carbon fibre, composites, fibreglass and metal. Its 0.4 hp motor drives the collet at a maximum 5500 RPM. A safety-lock throttle lever prevents accidental starts during handling or tool changes.
Sustained air-tool performance under load
Because the grinder is pneumatic, output remains stable as long as the supply pressure and flow are maintained. The 1/4 in NPT female inlet accepts standard shop air lines. The composite housing reduces vibration transmitted to the operator during extended sessions, helping maintain control when working on tough materials such as metal or fibreglass.
Practical limits of the 1/4 in collet system
The tool ships with 1/4 in collet insert 50013 and 6 mm collet insert 50016, so only accessories with matching shank diameters can be used. Maximum speed is fixed at 5500 RPM; accessories rated for lower speeds must not be fitted. Buyers who need larger shank capacities or higher rotational speeds will require a different grinder.

Questions about this item
How loud and how much air does the 0.4 hp Dynabrade 47202 use during continuous operation?
The 0.4 hp motor runs at 5500 RPM with a 1/4 in NPT female air inlet; actual noise level and CFM consumption depend on your compressor and airline setup.
What compressor fittings and hose size must I already have to connect the 1/4 in NPT female air inlet?
You need a 1/4 in NPT male fitting on your air hose and a compressor that can deliver the pressure and volume this 0.4 hp grinder requires at 5500 RPM.
Will the included 1/4 in and 6 mm collets (Mfr. No. 50013 and 50016) accept the carbide burrs and mounted points I already own?
Yes, the two supplied collet inserts cover both 1/4 in and 6 mm shank accessories, so most standard burrs and points will fit directly.
