The outer (prepolishing) ring of this lap is the Tin Plus lap, which holds diamonds firmly, has a firm surface, and a low friction factor. It’s ideal for fast removal of subsurface damage from cutting.
The inner (polishing) ring of this lap is the Diamatrix synthetic ceramic, ready to be charged with diamond or oxide polish.
This lap works great with our line of Voodoo Magic Polishes and pre-polishing compounds.
This lap is recommended for repair cutting and rapid production work with a wide range of harder materials. This lap has exceptional performance with spinel, sapphire, chrysoberyl, etc.
This lap is not recommended for softer stones that do not play well with the Diamatrix polishing surface (7.5 hardness or less).
Double-charged laps are not for beginners.
Protips:
The polishing portion of this lap can, with pressure and speed, cause heat to build very rapidly. This can melt your dop wax, or release your CA or even epoxy, causing your stone to shift or even fall off the dop. Keep one finger in contact with the stone at all times to monitor for heat build-up – and moderate your speed and pressure.
