A Magna-Trap floor grinder normally runs individual magnetic tooling - but some jobs call for the coverage and consistency of a full 10-inch diamond disc. The EDCO 77618 adapter plate is the bridge: it bolts to the grinder and gives wedgeless Magna-Trap machines a flat, true mounting face for 10-inch diamond grinding discs, turning a tooling-plate grinder into a disc grinder in one hardware swap.
Use cases
Concrete surface prep. Run aggressive 10-inch diamond discs to profile slabs before coatings, overlays, or self-leveling underlayment.
Coating and mastic removal. PCD and crushed-diamond 10-inch discs chew through glue, thinset, and paint faster than segment-by-segment tooling on large areas.
Rental fleets. One adapter plus a shelf of discs lets a single Magna-Trap grinder serve customers who ask for grinding, glue removal, or prep - without stocking separate machines.

Frequently asked questions
Do I need this adapter to run diamond discs on a Magna-Trap grinder?
Yes. Magna-Trap machines hold individual magnetic tooling out of the box; the 77618 provides the flat bolt-up face a full 10-inch disc requires. Without it, disc tooling has nothing to mount to.
Which grinders does it fit?
EDCO Magna-Trap wedgeless floor grinders that list the optional 10-inch diamond disc configuration - including single-disc and dual-disc models. Check your grinder manual for the diamond disc adapter illustration, or ask us with your model number.
Will third-party 10-inch discs work?
Most 10-inch diamond disc plates made for EDCO-pattern grinders bolt to the adapter. Match the disc bolt pattern to the adapter and confirm the grit and segment style suit your slab and material.
When should I use a disc instead of magnetic tooling?
Discs shine on big open floors where full-width, even contact speeds production. Individual Magna-Trap tooling is better for spot work, edges, and quick grit changes. Crews that do both keep the adapter in the toolbox.
