LAPIDARY and JEWELRY SAW |
 The Ameritool 4" Lapidary Trim
Saw is the perfect tool for cutting valuable faceting material and pre-forming
cabochons. The saw table is flat so it is easy to trim oversized slabs and removable so clean up is
easy. The sturdy table measures 6" X 10". The saw housing is made of unbreakable
cross-linked polyethylene - No rusting, no messy oil, uses water only.
The 1/4 HP equivalent variable speed ball bearing direct drive motor allows the saw to run
fast enough to use ultra thin diamond blades and it is powerful enough for sintered
diamond blades.

silicon carbide discs and diamond compound finishing systems. All discs come with a
pressure-sensitive adhesive backing. They will adhere to most laps or backing plates.

Amerishine Resin Bond Diamond Discs
A great advance in the smoothing and pre-polishing of facets, inlay and lapping small flat
surfaces. TheAmerishine Resin Diamond Discs grind fast yet leave smooth
scratch-free surfaces. Diamonds are locked into a multi-layer resin surface delivering a long
consistent life. (Not recommended for heavy stock removal.) When selecting an
Amerishine Resin Bond Disc, choose one mesh size coarser than an
electro-bonded diamond disc.
(*Replaces an
electro-bonded disc mesh size.)
