Diamond grinding disc, Ø 250 mm, for medium-hard floors, grit size 30, concrete up to C40 and tile adhesive residues
The diamond grinding disc for medium-hard floors is ideal for grinding medium-hard concrete floors, including old tile adhesive residues: Ø 250 mm with 20 premium segments in grit size 30, suitable for concrete up to C40. It removes material quickly and evenly, preparing the surface for the subsequent grinding and polishing stages, both wet and dry.
Segments and construction
The 20 segments, each measuring 40 x 10 x 10 mm, sit flat and exposed on the disc. Thanks to this open design, the extraction system works much more effectively when using an Industrial vacuum cleaner during dry grinding. No pressure needs to be applied to the machine, which makes working on large surfaces easier and produces a very clean finish.
- Diameter: Ø 250 mm
- Segments: 20 premium segments
- Segment dimensions: 40 x 10 x 10 mm
- Grit size: 30
- Mounting hole: 19 mm
- Weight: 3.1 kg
Materials
Before sanding, determine the hardness of the concrete, as this determines which disc to use: concrete up to compressive strength class C50/60 is considered hard, C40 is medium-hard, and C30 is soft. This disc has a medium-bond for precisely this range. For hard concrete up to C50, use our grinding disc for hard floors; for soft concrete up to C30, use our grinding disc for soft floors. If there is also paint or varnish on the floor, our grinding disc with a grit size of 16 is the coarser option. After using the pad, you can proceed step by step to a polished finish using our diamond grinding pads with grit sizes ranging from 50 to 1500.
- Suitable for: concrete floors up to C40, medium-hard concrete
- Removes: Tile adhesive residues
- Operating mode: wet and dry
Compatible machines
The disc is screwed directly onto the grinding head using the four M12 x 25 countersunk screws supplied with our floor grinders, tightened to 70 Nm. No adapter holder is required.
- BSM250/E-PRO: 2200 watts, fixed speed, the straightforward machine for removal and levelling.
- BSM250/Xtrem: 2500 watts brushless, continuously variable speed from 400 to 2000 rpm, from coarse sanding to polishing.
- Adapter plate Ø 250 mm: Screwed on in place of the disc, it holds diamond grinding shoes and pads via a quick-change system, which is useful when changing grit sizes frequently.
The disc also fits other floor grinders with a 250 mm working width. The full range can be found under our diamond sanding discs.
