This ground-up redesign takes the best of THE BOSS™ long-throw orbitals and incorporates many of the technical innovations of the G9. The project continues the collaboration with our new manufacturing partner with all components being exclusively designed to our specifications.

For G21, we ve taken the shape of the G9 and extended the body housing by 20% to accommodate a big block 1,100-watt motor. This represents a 22% increase in power versus the previous tool. In the G21, the motor delivers a speed range of 3,000 to 4,500 orbits per minute.

Among the more innovative features of this tool is its cooling strategy. Due to its long-throw articulation, the G21 could not integrate fan cooling in its counterbalance like the G9. So we engineered the G21 with its cooling fan integrated into the backing plate. This new backing plate technology was developed exclusively for these machines and is undeniably best in class.

Balancing the combined weight of a backing plate, buffing pad, and the liquid on the pad translates into less vibration and a smoother running machine. For instance, microfiber pads generally weigh nearly twice as much as a foam pad so fine tuning is beneficial. Our innovative Weight Optimization System consists of three uniquely engineered fasteners, each weight-matched to a Griot s Garage pad type to ensure you ll enjoy best in class performance from these machines.

It should be noted that long-throw polishers are not ideally suited for application of waxes and sealants. Their large throw tends to cure the wax unevenly with the exception of our BOSS™ Finishing Sealant whose formula is designed to comply with the heat cycling of long-throw orbits. The G8 or G9 are our most suitable tools for wax application. Also, the G21, when converted to a 5 backing plate and fitted with a BOSS Microfiber Fast Cutting Pad is our most aggressive paint correcting combination.
