In the world of stone fabrication, the difference between a “good” edge and a “perfect” edge often comes down to the reliability of your machinery. Whether you are processing granite, quartz, or marble, your shop needs equipment that delivers consistent results without becoming a maintenance nightmare.
At Stone Fabricator Solutions, we are proud to feature the RDM Flat Polisher by Sasso—a machine that represents five decades of real-world fabrication experience distilled into a compact, industrial-grade powerhouse.
Here is why the RDM is becoming the go-to choice for shops looking to scale their production without sacrificing quality.
Built for Longevity: Design That Makes Sense
Many machines look great on paper but fail in the wet, harsh environment of a stone shop. The RDM was designed with “maintenance-first” thinking:
Exterior-Mounted Motors: Water is the enemy of electronics. On the RDM, motors are mounted outside the water zone. This simple design choice prevents encapsulated bearings from failing and significantly extends the service life of the machine.
Hot-Dip Galvanized Steel Frame: While many manufacturers rely on paint—which eventually chips and peels under constant exposure to water—the RDM features a hot-dip galvanized framework. It’s built to resist corrosion for decades.
Precision Alignment: The spindles are mounted on a CNC-machined plate, ensuring perfect level alignment from day one. This simplifies installation and keeps your edges accurate year after year.
Production Power in a Compact Footprint

Not every shop has thousands of square feet to spare. The RDM Compact measures just 91″ x 48″, making it ideal for modest shop spaces. However, don’t let the size fool you. It delivers heavy-duty performance:
8 Total Spindles: With six polishing heads and two micro-bevel spindles, you can process flat edges from rough to polish in a single pass.
High Feed Rate: Capable of a feed rate of three feet per minute, the RDM allows you to process backsplash and countertops rapidly and consistently.
Front-Accessible Spindles: We know that time spent on tooling changes is time not spent fabricating. Every spindle on the RDM is accessible from the front, allowing for quick, effortless changes to keep your production flowing.
Simple Controls, Professional Results
One of the RDM’s greatest strengths is its “elegantly simple” operation. You don’t need a master technician to run this machine. Its straightforward controls mean anyone in your shop can produce professional, high-gloss results on any material.
To support your workflow, the RDM also comes with six-foot heavy-duty feed tables to handle long pieces safely, with an optional tall feed support system available for oversized work.
