MPT Diamond Core Drill Bit

Description

The MPT MJ15002 Diamond Core Drill Bits cut clean, round holes through concrete, reinforced concrete, brick, block, and masonry walls and floors. They’re the go-to bits for pipe, conduit, drainage, aircon, and duct penetrations. Each bit has a diamond cutting edge that cuts quickly and accurately with minimal chipping around the hole. The 400 mm barrel drills through thick walls and slabs in one pass. All sizes use the standard 1¼”-7 UNC adapter, so they fit most diamond core drill machines, including MPT’s handheld and stand-mounted core drills. The series comes in six diameters from 2″ to 8″, covering small conduit holes up to large drainage and duct openings. It’s built for plumbers, electricians, aircon installers, MEP contractors, and coring specialists.
