BATT™ Lap by Gearloose The BATT™ is the standard for tin alloy laps. With more than 8,000 sold, it has established itself in Commerce and Competition time and again.
A SOLID cast tin alloy lap, with two usable sides, it still sells for significantly less than many commercial rolled tin laminated laps.
"BATT™ is a proprietary tin alloy which allows you to cut the flattest facets possible - quickly and easily."
PRIMARY USE: Polishing with 50-200K diamond.
SECONDARY USE: Prepolishing, fast and perfectly. 3K diamond is usually used.
Last Few Years: People are using them to CUT. Will not load up or foul when cutting quartzes.
Like many metal laps, the BATT™ is a permanent chargeable lap. They must be dedicated to a grit size. BATT™ success is its ability to retain diamond, so the user can never go to a finer sized grit once a lap is charged. A lap can be "promoted" to a coarser grit. A 60,000 polishing lap can be converted to a 3,000 prepolish or 1200 cutting lap for example, but you cannot go back to a finer size.
