DFG 500 Floor Grinder

To successfully grind large floor areas a heavy duty floor grinder is required. The DFG 500 gives complete operator control and at the same time has the correct weight to act directly onto the grinding plates to facilitate accurate and rapid grinding.

  • 500mm (19.7″) working width twin head design
  • 3Ø, high power single and twin speed designs
  • Removeable ballast weights and hydraulic raise/lower facility.


  • Push button hydraulic raise and lower facility
  • Anti vibration handle bar mounts
  • Screw type hand wheel allows machine to be accurately set to the surface
  • 50mm dust extraction port
  • Dust free when operated with SPE316 vacuum
  • Multi purpose
  • Dust free
  • Thermal overload protection
  • Maintenance free
  • Low noise
  • Low vibration
  • Safety start mechanism


The unique design of the DFG 500 has two ballast weights that can be removed, together with precise adjustment of the fulcrum for the rear wheel allows for perfect grinding in all types of situations. Environmental considerations are fully controlled with an adjustable dust skirt for dry use and a facility for using water when wet grinding. Noise is kept to minimum by use of high power 3 phase electric motors and drive belt systems.

The DFG 500 is manufactured to a high specification and operates using two grinding heads. A hydraulic raise and lower facility is easily operated by push button switches mounted on the handle bars. The net weight is in excess of 300kg but one operator can easily control the machine.

Low operational noise, little or no impact vibrations, consistent diamond wear rates and ease of operation make the DFG 500 an excellent choice for economical and productive floor grinding.

Twin Speed Option
The DFG 500 is also produced in a twin speed version giving operation speeds of 700 and 1400 r.p.m. The slower speed being designed and introduced for the grinding of terrazzo and marble applications when using the SPE polymer diamond system. Optional higher rpm head speeds are available upon request.

Typical Applications

  • Removal of dry crystallised (ATA) and wet adhesives
  • Slurry grinding on water miscible products
  • Provides superb preparation profile for thin film coatings (eliminates shadowing)
  • Accurate grinding of large concrete areas
  • Re-profiling of old concrete floors
  • Removal of old coatings and contaminates
  • Grinding and finishing of resin based terrazzo
