Dustless grinding and edging equipment are essential  for all floor contractors

These concrete floor grinders and edging tools are an essential part of every contractor's concrete grinding equipment because most of the larger grinding tools are not designed to feather out to the edges.

Diamond grinding is the preferred way to prepare floors for coatings, sealers, vinyl, overlays, polishing or decorative finishes and dry grinding is faster than wet with less cleanup and automatic pick up and collection of the dust via a dust collector/vacuum.

How diamonds grind concrete

The tools bove use angle grinders with diamond grinding cupwheels fitted which are surrounded by a dust shroud. The diamond segments will readily grind away concrete reducing it to a fine dust which is exhausted through the vacuum port to which is connected a vacuum dust collector using a flexible vacuum hose as indicated in the top picture.

Diamond grinding wheel for hard concrete

The diamond grinding cupwheels have diamond segments welded to them which are blocks of metal with diamonds dispersed throughout. As the metal wears away the diamonds are exposed and they cut the concrete. It is essential that the concrete dust and sands cut back the metal for the diamonds to work. For more information about segments  go to Grinding Hard Concrete.

How to use a diamond cupwheel

Concrete floor grinding with angle grinders requires the cupwheel to be held flat on the floor because it has many hard, rigid, metal segments welded to it which are not flexible.

The diamond cupwheel is held flat on the floor with light pressure while the grinder is started. Once the grinding begins the cupwheel must be moved in a circular motion to prevent grinding a depression in the floor.
