ShineMate EB351 3" 12mm | Cordless Mini Dual Action Car Polisher · Kit (battery & charger)$629.95 About ShineMate EB351 3" 12mm
A professional-grade cordless polisher built for precision. The ShineMate EB351 3" combines the safety of a dual action polisher with the power and torque of a pro-level car polisher.
The ShineMate EB351 is part of ShineMate’s flagship cordless DA range, the same series that includes the 5" 12mm, 5" 15mm, and 6" 21mm models. This 3" mini polisher is engineered for intricate work while delivering performance on par with ShineMate’s top-tier corded EX620 PRO Dual Action Polisher.
Powered by a high-torque brushless motor, the EB351 delivers exceptional cut for its size, with the refinement and safety of a dual action polisher. The 12mm orbit provides a perfect balance between correction power and smoothness, making it capable of everything from removing stubborn defects to finishing down on delicate paintwork.
A progressive accelerator switch allows on-the-fly speed control by pressing depth, while the electronic anti-stall feature automatically feeds more torque under load, keeping the pad spinning through curves and contours. With a 2000–5000 OPM range and a constant speed control system, you can adapt it to cutting or finishing work effortlessly.
Comfort hasn’t been overlooked. The EB351 features an ergonomic soft-grip body, balanced weight distribution, and vibration inhibition technology to reduce fatigue. With two 18V 5.0Ah batteries included in the kit, you get up to 120 minutes of runtime and fast charging, with built-in overcharge protection.
Whether you’re a professional looking for a cordless precision tool to complement larger machines, or a serious enthusiast who wants pro-grade performance without the cord, the EB351 is a serious contender.
Why choose the ShineMate EB351 3"?
The EB351 is built for detailers who need the control of a 3" mini polisher with the torque and consistency of ShineMate’s professional corded machines. It’s ideal for tight areas like bumpers, A-pillars, door handles, and wheel faces, places where a 5" or 6" car polisher feels too big.
Compared to the EB350, the EB351’s larger battery capacity, progressive trigger, on/off switch lock and professional-grade design make it a better fit for high-volume or commercial work. And when compared to the EX620, you get similar torque and anti-stall technology, but in a cordless format for complete freedom of movement.
Like all ShineMate machines, the EB351 is built entirely in-house, with CNC precision machining on all core components for durability, balance, and smooth operation. If you want a cordless dual action polisher that delivers pro-level results without compromise, the EB351 should be at the top of your list.
