The ShineMate EB351 6" 21mm combines cordless freedom with the longest throw in the series, making it the go-to car polisher for fast, efficient correction.

The ShineMate EB351 6" 21mm combines cordless freedom with the longest throw in the EB351 series, making it the ultimate cordless DA polisher for rapid correction on large, flat panels. With its massive 21mm orbit, this buffing machine covers more area per pass than any other model in the range, cutting down your working time while still delivering a refined finish.

Designed for professionals and serious enthusiasts, this top-tier Cordless Polisher features a high-torque brushless motor, precision CNC internals, and advanced load-sensing anti-stall technology. The result is a car polisher that stays smooth and balanced while delivering the speed and correction power needed for big jobs.

Compared to the EB351 5" 15mm, the 21mm model offers faster cutting and greater efficiency on large, open panels like bonnets, roofs, and doors. While the bigger throw prioritises speed, ShineMate’s vibration inhibition technology and ergonomic design ensure that comfort and control are never compromised.

This flagship cordless model matches the performance of the EX620 professional corded range, giving you pro-level correction without the restrictions of a power cable. Whether you’re tackling heavy defects or performing a high-speed one-step polish, the EB351 6" 21mm is built to deliver outstanding results anywhere.

Why choose the ShineMate EB351 6" 21mm?

The EB351 6" 21mm is built for detailers who need maximum correction power in the shortest possible time. Its large throw covers more surface area per pass than the 12mm or 15mm versions, making it the best choice for working efficiently on large vehicles or expansive panels.

Compared to smaller throw machines, the 21mm delivers faster cut and improved defect removal on flat areas, while still maintaining the safety and refinement of a Dual Action polisher. If speed and coverage are your top priorities, this is the cordless model to choose.

Like all EB351 polishers, it features a high-torque brushless motor for consistent performance, CNC precision for durability, and ShineMate’s load-sensing anti-stall system to keep the pad rotating under pressure. From the grips to the patented multi-hole backing plate, every part is engineered for professional results and long service life.
