Griot'S Garage G21 Long-Throw Orbital Polisher

Regular price $260.00
The Griot's Garage Long Throw Orbital Polishers have been engineered from the ground up, so experienced enthusiasts or professionals can achieve a best of show finish! The three key terms, performance, control and comfort highlight exactly what innovation and features Griot's Garage packed into the G15 and G21 units. The G15 offers a 15mm throw and the G21 offers a 21mm throw. Both units perform exceptionally in terms of power and imperfection removal, but the lower throw on the G15, paired with a 5" backing plate, allows you to hit those tighter areas easier. The G21 features a 6" backing plate and the larger throw, allowing it to tackle imperfections on larger panels in much less time. Take a look at the in depth features of this unit below!

  • Insanely powerful 1100 watt, 10amp motor delivers enough torque to maintain consistent pad rotation
  • Fan-cooled backing plate with weight optimization system to match pad weight
  • Precision CNC Machined Counterbalance for smooth operation
  • Quick-connect 10' power cord (16-gauge SJO Rubber) detaches for easy storage and
  • Safety restart and heat protection circuitry
  • Temperature management system features electronic heat-protection circuitry,
    enhanced airflow via screened tri-intake, advanced fan-cooled motor and backing
  • Quick access brush side ports allow for easy maintenance
  • Low-resistance premium sealed bearings ensure long-service life
  • Hardened gearset lubricated with Mobil MobiluxTM Molybdenum Grease for long
    working life

  • Variable speed trigger
  • Constant speed control maintains consistent set speed range of 3000-4500
    orbits per minute
  • Quick response delivers the power when you want it, acutely focusing the control you have over the tool
  • The trigger lock allows you to set the speed you want and operate the tool independent of the trigger

  • Six double-shot rubber grips ensure you stay comfortable all day by absorbing energy
  • Ergonomic design features unique Pistol and Platypus Grips for even distribution of pressure

From The Manufacturer 

Need professional-grade paint correction? The feature-packed G21 is the most capable paint perfecting tool we’ve ever created.

  • 21mm orbit, large pad surface area produces unparalleled polishing effectiveness
  • 1,100-watt 'big block' motor delivers powerful paint correction
  • New design is a 22% increase in power versus previous tool
  • Throttle trigger allows precise, incremental speed control
  • Innovative fan-cooled backing plate extends pad life

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.
