A True Workhorse for Small Area Concrete Surface Preparation
When it comes to surface prep, speed and consistency are everything. The Diamond Products 3x 5″ Core Prep DS3011 Planetary Head Concrete Polisher (32947) is built to deliver professional grade results on small concrete polishing and grinding projects. Designed for contractors who demand reliability and precision, this powerhouse combines a rugged planetary head system, heavy-duty FEIN motor, and a precision-driven platform to give you a flawless finish, faster than ever before.
Planetary Gear System: Built for Balance and Speed
At the heart of the DS3011 is a planetary, gear-driven system that powers three 5″ diamond polishing pads or grinding discs. Unlike single-head polishers, this configuration keeps the platform stable while producing a smooth, even finish across the entire surface.
Each 5″ platen spins at high rotational speeds, over 2,000 RPM, while the 12″ platform rotates at a lower rate, maintaining balance and control. This dual-motion design optimizes pad contact and reduces swirl marks, letting you grind, hone, and polish up to five times faster than with traditional machines.
FEIN Variable Speed Motor for Professional Control
The DS3011 is powered by a 2 HP FEIN variable speed motor, a trusted name in industrial-grade reliability. The variable speed control lets you fine-tune RPMs for different stages of the polishing process, from aggressive grinding to high-gloss finishing.
With a 115V/60Hz power supply and 11-amp draw, this unit offers both flexibility and the torque needed for demanding concrete prep tasks.
