DARKSIDE - a BATT relative

The DARKSIDE is a lightweight lap, made of the specially developed material coated onto an aluminum baseplate, then machined both sides for flatness. We have been using them since Summer directly on the lap spindle. For its thickness it is surprisingly rigid.

Like all Gearloose laps, the polishing mechanism relies on surface complexity for polish retention, and lubricity for reduced heating and higher polishing efficiency. Because the composite contains carbon, it has a natural affinity for diamond, but the hydrophilic domains accept oxide polishes.

The Darkside is a RESURFACABLE LAP. Within reason, if a lap jam does not destroy the lap, you get another chance or two. If A stone fractures and chips embed, the Darkside can be resurfaced.

This is an exceptional value for a general purpose polishing lap. It can be used with diamond or oxides, and it produces a quality finish quickly.
