The EDCO Magna-Trap Medium Concrete LEFT-Hand Arrow Part #QCAR-MC-0030 is a medium-aggressiveness diamond grinding attachment built for concrete restoration contractors and flooring installers who need hard glue, mastic, and coatings stripped before a new floor goes down. The directional Dyma Arrow tooling pattern removes bonded adhesives and surface coatings at a fast pace while leaving behind a smooth, consistent CSP-2 profile - the balance point between aggressive material removal and a finish that is ready to accept the next coating or flooring adhesive.
Use Cases
- Stripping hard glue and mastic residue ahead of a new flooring installation
- Removing old coatings, paint, and sealers from concrete slabs
- Fast concrete grinding for surface leveling and general prep work
- Achieving a smooth CSP-2 profile so new coatings or adhesives bond properly
- Retrofitting Classic-Style grinders for glue-stripping jobs via the Multi-Tooling Disc
Because the tooling is directional, left-hand and right-hand Arrows are designed to rotate opposite one another on dual-disc Magna-Trap grinders, which keeps the machine tracking straight and evens out wear across the disc. On single-disc machines, the left-hand Arrow works alone, matched to that grinder's rotation direction. Medium-grit tooling like this sits between EDCO's soft-concrete and hard-concrete Dyma Arrow options: aggressive enough to cut through bonded glue and coatings quickly, but controlled enough to leave a CSP-2 finish rather than the deeper, coarser profile a hard-concrete grit would leave behind.

Frequently asked questions
What does a CSP-2 rating mean, and why does it matter?
Concrete Surface Profile (CSP) is an industry scale used to describe how rough or smooth a ground concrete surface is after prep work. A CSP-2 finish is a light-to-moderate profile - smooth enough to accept thin-film coatings and flooring adhesives, but with enough texture for the new material to grip. It is a common target profile after glue or coating removal, ahead of epoxy, polyurea, or new flooring installation.
Which EDCO grinder models is this Arrow compatible with?
It is built for Magna-Trap Floor Grinders in single and dual-disc configurations, and for Magna-Trap Turbo Grinders in 7-inch, 9-inch, and 10-inch sizes. It can also be run on Classic-Style EDCO grinders once retrofitted with the Magna-Trap Multi-Tooling Disc.
What is the difference between left-hand and right-hand tooling?
Left-hand and right-hand Dyma Arrows are mirror images of each other, matched to opposite rotation directions. On dual-disc grinders they are typically run as a pair (one left, one right) so the discs counter-rotate for a straight-tracking, evenly worn grind. On single-disc machines, the hand orientation is matched to that specific grinder's rotation.
How aggressive is medium tooling compared to coarse or fine options?
Medium-grit Dyma Arrows sit in the middle of the Magna-Trap tooling range. They remove material and strip bonded glue or coatings faster than fine or soft-concrete grit tooling, while leaving a smoother, more controlled CSP-2 finish than coarse or hard-concrete grit tooling, which is built for more aggressive stock removal and leaves a rougher profile.
Can this Arrow be used for concrete polishing prep?
This medium-grit Dyma Arrow is built for glue removal, coatings removal, and fast grinding rather than the fine, progressive-grit sequence used for polished concrete. For polishing work, pair it with EDCO's dedicated polishing tooling line.
Discount Cleaning Products stocks EDCO Magna-Trap tooling for concrete restoration and flooring contractors who need dependable, directional diamond tooling that matches the job at hand. The Medium Concrete LEFT-Hand Dyma Arrow rounds out a full CSP tooling lineup, so crews can move from glue and coatings removal straight into surface prep without swapping grinder platforms.
