A precision lapping plate at the heart of the Shapton system, the DGLP is capable of flattening a hone to within 5 microns across a hone’s surface. It is recommended only for the Shapton stones.
The Diamond Glass Lapping Plate (DGLP) is a highly engineered diamond plate for keeping the Shaptons flat. It’s used only on Shaptons and never on any other kind of stone. Using any other kind of stone to flatten Shaptons is not recommended by Shapton. The DGLP should be considered a “must have” for serious Shapton users.
