DS3011 — 12" Handheld, Active Driven, Planetary Polisher
Proudly Made in USA. The second generation of the original DS301 (World of Concrete Tool of the Year), the DS3011 sets the industry standard for hand polishing concrete and stone. Its active planetary drive is 5 times faster than single-head machines, using three 5" diamond discs to deliver a flatter, swirl-free surface with minimal effort.

Operation & Video
Recommended setup & discs
- Single-speed motor (~2,100 RPM): Higher power and improved motor cooling compared to the earlier 2,500 RPM variable-speed DS301, covering grinding, honing, polishing, and buffing on one speed.
- Discs & pads: Use lightweight brazed diamond discs (starting from 30 grit) and resin polishing pads on original rigid Velcro backup pads. Do not use heavy metal discs.
- Power line: Run on a 10–15 amp breaker with a 12-gauge extension cord so proper power keeps the motor from overheating during aggressive lower-grit material removal.
- Dust collection: Operates wet or dry; whenever water is not practical, always connect a vacuum to collect dust.
Concept video (YouTube)

Note: This older demonstration video shows the previous variable-speed DS301 using heavy metal discs for aggregate exposure. The current DS3011 uses a single ~2,100 RPM speed and lightweight brazed discs instead to protect the motor while delivering the same workflow.
Other hard surfaces (glass & metal): Because the DS3011’s 12" active planetary action delivers a flat, swirl-free finish, a number of artists, architects, and sculptors have adapted the machine with their own specialty abrasives and polishing media for hard surfaces such as glass and metal. Please note that INTER-TOOL does not provide official media recommendations or procedures for glass or metal—those applications are developed by and remain at the discretion of the user.
