Diamond core bits are used for drilling holes in hard and soft materials with or without steel reinforcing, such as cured and reinforced concrete, pre-stressed concrete, asphalt, brick, block, stone for air-conditioning, water pipe, gas nozzles, electric switches in walls and floors.                                              

SANG diamond tools carries a range of masonry core bits ideal for drilling concrete, and reinforced concrete. Our concrete core bits are even strong enough to drill medium steel and rebar. Higher diamond concentration and quality allow our concrete core bits to drill quickly and reduce cost per hole.
