Lortone 20 inch Oscillating Lap for polishing slabs
with grinding and polishing pans
Largest oscillating lap we currently stock for those larger pieces. More surface area for not much more than the 15" unit so great value for money.
These redesigned laps from Lortone use a precision shaft-driven offset that produces a true orbital action of over 1300 cycles per minute. Get flat, smooth surfaces on geodes, bookends and slabs quickly and quietly, without the bounce and splash of ordinary vibrating laps.
The Lortone innovative elastomer support system eliminates all of the old-fashioned lap parts - no more springs, balls or cables! The heavy gauge welded steel frame provides great stability and won’t walk around on the floor or bench.
Includes cast aluminum grind and polish pans (one of each). Comes with heavy-duty bearings & easy to level adjustable feet.
Use fresh grit. As the rocks grind down, the grit gets contaminated with rock dust and becomes less effective. By changing your grit every 4-8 hours you'll get maximum cutting efficiency.
Keep Everything Clean!! We can't stress this enough. Any grit that is carried over to a finer stage will cause scratches and prevent the stones from polishing. Make sure that there are no small rock chips or other items on the polish pad. Even household dirt can ruin an otherwise good finish. Keep your polish pan in a plastic bag.
