These flat, untempered glass plates measure 560mm x 225mm x 10mm and have beveled edges for an extended lifespan. When paired with adhesive-backed abrasives, they are a quick and cost-effective way of flattening waterstones, or establishing flat surfaces on workshop tools.
We find this size of plate excellent for flattening the soles of large Japanese smoothing planes in the range of 65mm to 70mm.
This piece of glass has been sized to fit two standard sheets of sandpaper when they are laid end to end.
