The EDCO Magna-Trap M101 medium concrete package is the dual-disc grinder bundled with a complete tooling kit sized for medium-hardness concrete. It is the right starting point for restoration contractors, flooring installers, and surface-prep crews who need to walk on a job site, plug in, and grind without spending a day sourcing and matching segments to substrate.
Built for medium-hardness concrete prep
The M101 package solves the most common surface-prep buying mistake: ordering a grinder without the tooling that matches the floor. Medium-hardness concrete is the widest band of slabs in commercial work - typical interior pours, warehouse floors, retail buildouts, and most older slabs that have not been pre-densified. EDCO ships this package with the segments, dots, and PCDs that actually cut on that hardness band, which means the operator is grinding on day one instead of returning to the supplier for the right tooling.
Use cases
- Coatings removal: stripping epoxy, paint, urethane, mastic, thin-set, and carpet glue from concrete before recoating
- Surface preparation for new coatings to achieve CSP profiles per the ICRI Concrete Surface Profile guidelines
- Concrete leveling on uneven slabs and lippage at cold joints
- Decorative concrete prep before stain, dye, or polished-concrete buildup
- Trip-hazard removal at sidewalks and warehouse transitions
- Joint and ledge cleaning before patching, leveling, or recoating
What ships in the package
One EDCO Magna-Trap dual-disc floor grinder, 22-inch working width. Six Magna-Blades (three left-hand, three right-hand). Six Double Dyma-Dots in grey for medium concrete. Six Dyma-Segs in grey. Six PCD-with-backing segments (three left-hand, three right-hand). The PCDs are the heavy hitters for sticky coatings; the Dyma-Dots and Dyma-Segs are the daily-driver metal-bond segments that cut medium-hardness concrete fast and stay efficient through the segment life.
How operators talk about the Magna-Trap
On contractor forums and in field reviews, the Magna-Trap line is praised most for two specific design choices. First, the magnetic Slide-On tooling: no wooden wedges, no jamming, no skinned knuckles when the operator changes from a cutting segment to a finishing segment mid-job. Second, the counter-rotating discs: because the two discs spin in opposite directions, the side-pull torque cancels, and the operator is not fighting the machine to keep it tracking straight. That second point is what makes the Magna-Trap workable for one-person crews. A pull-side single-disc grinder is exhausting for a full shift; a counter-rotating dual-disc is not.
Productivity
EDCO documents the Magna-Trap dual-disc at approximately 400 to 500 square feet per hour at a 1/32-inch cut depth using Dyma-Serts. Field productivity varies with concrete hardness, contamination, vacuum capacity, and operator pace, but the published number is a fair planning baseline for medium-hardness slabs.

Frequently asked questions
What does medium concrete actually mean for tooling selection?
Medium hardness on the EDCO color-coded chart is the middle band - typical interior commercial slabs that have not been mechanically polished or chemically densified. The grey segments shipped in the M101 are matched to that band. If your slab has been densified or it dates back a few decades and has cured very hard, the soft-bond segments (a different package) will cut faster; on very fresh or very soft pours, the hard-bond color is the right call. EDCO publishes a hardness/segment chart, and Discount Cleaning Products can help you match the kit if you can describe the slab.
Is this rental-spec or contractor-owned?
The package configuration is the same one EDCO supplies into the rental channel, but it is sold to end users. Rental fleets like it because the bundle is purpose-built for the most common substrate they rent the machine onto.
Do I need a vacuum to run this machine?
For indoor work, yes. OSHA Table 1 silica-dust requirements apply to most concrete grinding, and a paired HEPA vacuum is the practical way to comply. EDCO sells matched vacuums, and Discount Cleaning Products can quote a complete grinder-and-vacuum package.
Can I use this for polished concrete buildup?
Yes for the prep step. The metal-bond Dyma-Sert family is the early-grit step in a polished-concrete buildup. For the resin pads in the polishing buildup itself, you will add a separate resin tooling kit on the same machine.
How long do the Dyma-Dots and Dyma-Segs typically last?
Segment life varies more with concrete hardness, depth of cut, and rate of feed than with brand. On medium-hardness concrete in coatings-removal work, a set of six grey Dyma-Segs typically removes between 800 and 1,500 square feet of mastic or thin-set, and a set of six PCD-backed segments removes between 2,000 and 4,000 square feet of resilient coating before they need to be replaced. Soft slabs and abrasive contamination shorten the life; well-cured slabs and clean coatings extend it.
What size of project is the right fit for this single machine?
A 22-inch dual-disc grinder is the right size for projects from a few hundred to a few thousand square feet per day. Above that footprint - for example, a 50,000-square-foot warehouse coating-removal job - you would step up to a larger Magna-Trap or run two M101 machines in parallel. Below it, for a single small room or a few stairs, a smaller hand-held grinder may be the better tool.
