Apollo Professional Core Bits - 3/16" to 2-3/4"
Apollo’s best core bit performs fast, aggressive and chip-free drilling on natural stone, engineered stone, porcelain tile, and other hard stone. Its high quality diamond gives these core bits an excellent lifespan. It is suitable for both dry or wet use as long as the speed is kept below 6500 RPM. With a standard 5/8”-11 arbor, we recommend using the core bit on a variable speed angle grinder or a hand drill through the use of an adaptor.
Adaptor is available and sold separately
