Wokin masonry bit is perfect for drilling large 3-1/8 inch holes in brick, block and concrete using SDS-Plus rotary hammers. Heavy-duty carbide teeth break the material more efficiently, enabling up to 40% faster drilling. The versatile two-piece design allows users to drill with several different core bit sizes using a single adapter. The bits we sell already include a pilot drill bit and SDS plus adaptor, no need to buy additional items only the actual rotary hammer drilling machine. Centering pilot bit allows for easy alignment of the hole and precise spot drilling. Core bit cuts with the outer cutting edge only. The inside core must be removed to allow for deeper hole drilling applications beyond 2 inches.
