Looking for a reliable floor grinder that can handle both wood and concrete with ease? David Friedland from Hyper Grinder recently demonstrated their variable speed I-4 wood model, and it's impressive.

This four-horsepower machine stands out for its versatility and durability. The adjustable speed control—ranging from 500 to 1,000 RPM—gives operators complete control with just a simple turn of a knob. Whether you need a gentle touch or more aggressive grinding, this machine adapts to your needs.

Built to Last

What sets the I-4 apart is its engineering. The counter-rotating planetary action creates alternate forces working against each other, resulting in a smoother, more efficient grind. Heavy-duty helical ring gears and a triple planetary gearbox ensure this machine can withstand demanding professional use day after day.

Quiet Operation, Impressive Results

One of the most notable features? It's remarkably quiet. During the demonstration, the machine ran smoothly across different speeds—500, 800, and 1,000 RPM—with minimal noise. David typically operates it between 800-1,000 RPM for optimal results on wood floors.

Whether you're working on wood or concrete, the Hyper Grinder I-4 delivers professional-grade performance with the durability contractors demand.
