The Diamond Pacific Vi-Bro-Lap Vibratory Laps produce flat surfaces on geode halves, agates, petrified wood, and other materials and specimens while relieving you of the frustration of a nagging labor-intensive process during your lapping process.

The Vi-Bro-Lap can accommodate a number of specimens at the same time. The tempered aluminum lap plate is grooved in a criss-cross pattern which continuously refines and circulates the abrasive grits as they are crushed to smaller and smaller sizes between the lap plate and the workpiece.


While the Vi-Bro-Lap plate oscillates, work-pieces rotate in the pan. This gives a faster grinding surface speed, distributes abrasives, ensures a flat polished surface, and equalizes wear on the lap plates. When the work piece is ground flat and satin smooth, use the felt polishing pad with a fine polishing compound to obtain a fine mirror-like finish on your workpiece.

For general-purpose lapidary use, a sequence of tumbling grits in 60/90 coarse, 220 coarse, 400 fine, 600 pre-polish, 1000 pre-polish, , then a suitable polish slurry will produce a satisfactory shine on most lapidary materials. In general, a larger number of grit steps will lead to a better final polish.


  • Lap plates are manufactured from heat treated aluminum alloy to produce a tough, wear-resistance lapping surface. Each surface has a milled V-grooves in a square pattern to allow grit to circulate.
  • Suspension is controlled by aircraft strength cable, adjustable for fine leveling to keep your workpieces evenly distributed over the lap plate surface
