The grinder takes a number of different attachments, not included in the base machine rental rate, that attach magnetically into slots in EDCO's Magna-Trap system. A series of six tool holders (3 on each disc) accept a number of different grinding tools. Dyma-Dots are used for light grinding and removal of thin surface coatings while the Dyma-Seg segments are used for more aggresive grinding and removal tasks. The Magna-Blades are carbide cutters, similar in function to the Flaky Jakes system used on our older grinder, that are designed for removal of thicker coatings. More information on these can be found in the following links.
This tool is excellent for removing surface coatings such as heavy paint accumulations, drywall mud splatter, Thinset, buildups of printing press ink or machine tool oil, or anything that is just too much to be sanded. It can also be used to grind high spots from the concrete with its 1/32" removal rate per pass you'll grind approximately 400-500 sq. ft. per hour using the Dyma-Segs. For a more compact unit with plenty of power our popular 9" Turbo Grinder is another excellent choice and is better suited for actual concrete grinding. To achieve even faster removal rates our Concrete Planer is an even faster way to go. The dual head grinder is a hefty lift so it will take two men to unload it at your jobsite. It requires a 20 amp breaker to run it and water should be used to help hold down dust.
