Frequently Asked Questions
What machines do these dots fit?
They fit EDCO Magna-Trap floor grinders in single or dual-disc models, Magna-Trap Turbo grinders in 7-inch, 9-inch, and 10-inch sizes, and classic-style grinders retrofitted with a Magna-Trap Multi-Tooling disc.
What does the medium concrete rating mean?
The medium bond is matched to medium-hardness concrete. Bond hardness is paired to concrete hardness so the diamonds wear at the right rate for efficient grinding and tool life.
What surface profile do they leave?
They produce a Concrete Surface Profile (CSP) rating of 1-2, a relatively smooth profile suited to coating removal and leveling.
How many dots come in a pack?
Each pack contains 3 double diamond grinding dots.
What can they remove?
They remove general-purpose epoxy, mastics, thinsets, waterproofing coatings, and thin layers of concrete to create a level surface without gouging.
