Adamas distributes the versatile BATT alloy lap. This product is a superior replacement for copper and tin laps.
You can use your favorite oxide slurry, Battstik or diamond powder and a little water to polish facets to a fine finish.
You can pre-polish on the BATT by charging the lap with 8,000 mesh or 3,000 mesh diamond compound.
