About the Diamond Floor Grinding Disc (Blue)
At 230 mm this disc is sized for walk-behind floor grinders, where the weight of the machine does the cutting and the disc only has to stay flat. Square segments give a consistent scratch pattern across the full width, which is what makes the next grit step predictable on a large pour.
Typical applications
- Concrete floor preparation — Levelling slabs, removing trowel burn and opening the surface before coating.
- Coating removal — Grinding off epoxy, paint and thin levelling compounds.
- Large-area work — Warehouse, workshop and retail floors where hand grinding is not practical.
How to choose the right specification
- Fitting first — Velcro backing for quick changes, bolt holes for machines that clamp the disc — check your grinder's plate.
- Grit sequence — 16# or 30# to open and level, then step through 50# / 120# before resin polishing.
- Segment type — Square segments for aggressive flat grinding; if you need a finer finish step, switch to metal bond discs.
Supply, packing and OEM
Packed in poly bags or boxes, 50 pcs per grit. We press the segments with a defined height tolerance so a set of discs wears evenly across a wide machine — mismatch here is what causes the ridges contractors complain about.
Standard packing is poly bag / box, minimum order 50 pcs per grit per size, with mixed sizes accepted on a first order. Bulk orders typically ship within 25–40 days after deposit, FOB Shanghai or Ningbo — about 2.5 hours from our workshop in Danyang.
Most of this item ships to Canada, Europe, Australia, Japan, the Middle East and South America. Tell us the destination market and we match the sizes, thread standard, marking and packing language it uses — metric for Europe, Japan and South America, imperial where the trade still buys in inches, and carton copy in the language your customers read — then quote FOB, CIF or DDP against your order size.
