✅ Perfect for large panel correction with complete mobility.
What Makes It Special?
The HLR21 brings the aggressive 21mm orbit to cordless operation, transforming how professionals approach large panel correction. The weight reduction versus corded models (1.95kg vs 2.7kg) combined with eliminating cable drag makes this significantly easier to control during extended sessions.
- 150mm (6") backing plate with powerful 21mm orbit.
- 18V cordless iBrid technology for unrestricted movement.
- 30-40 minutes battery life at full power.
- Fast 50-55 minute charge time with dual charger.
- New anti-spinning ring crucial for preventing holograms.
- Advanced gear technology reduces noise and vibration.

Pro Tips From Ultimate Finish
"The cordless 21mm throw sounds mental on paper but works brilliantly in practice, we use this for large panels where the 21mm orbit earns its keep bonnets, roofs, large side panels. The anti-spinning ring is essential on this machine to prevent holograms on soft paint. Still requires the same respect and technique as corded 21mm machines, but the mobility transforms workflow. Keep batteries rotating on the dual charger and you've got unlimited runtime."
How To Use
1. Fully charge both batteries before starting correction work.
2. Select pad size appropriate for large panels (165-205mm).
3. Check LED indicator for full battery charge.
4. Set speed dial based on paint system hardness.
5. Work large flat panels exploiting cordless mobility.
6. Maintain constant motion 21mm orbit covers ground quickly.
7. Allow anti-spinning ring to function when lifting from surface.
Important Notes
⚠️ 21mm orbit requires experience practice technique before customer vehicles.
⚠️ Best for large flat panels use smaller orbit for curves and intricate areas.
⚠️ Battery swap critical before complete depletion to maintain performance.
