RM350 – Versatile Concrete Grinder

The Newgrnd Rhino RM350 is targeted towards contractors wanting the convenience of a smaller unit, but not wanting to compromise on power.

The additional horsepower paired with the added weight increases removal & prep production 35% when compared to the RM250.

For its weight and size the RM350 is a beast when it comes to concrete removal, concrete (or other hard finish) preparation, and concrete polishing. 

The versatility of this unit is what our customers love most!

Whether you are grinding or polishing concrete, terrazzo, or some other hard surface, this versatile grinder will help you get the job done quickly and efficiently.
