Apollo A-Team 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 professional grade diamonds gives these core bits an excellent lifespan.
 
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 (sold separately).
 
Another helpful accessory to have to keep the diamonds in good shape and prevent the drill bit / core bits from burning out is to use a sharpening stone (sold separately). 
 
NEW: Popular Diameter like 1-3/8", 2", 3" Core Bits available now with Vacuum Brazed Diamonds on the side (inside & out) for added protection and faster coring.
