The Milwaukee Core motor has been the staple for concrete coring rigs from the beginning. Many other manufacturer's even use the Milwaukee core motor on their coring machines. The Milwaukee rigs are best for use in the 4"-14" concrete coring applications. Available with a vacuum base these machines can attach to the concrete work surface and hold firm without leaving a mark. The Milwaukee core rig can even be use horizontally on a wall to drill when necessary.
Standard 1-1/4"x7 thread will fit most common core bits
, barrels and core bit adapters
down to 5/8"x11 or other sizes. Milwaukee does not currently make a handheld core drill or larger core drill motor for drilling 16" and larger.
