Core Drills, Core Drill Bits, Core Drill Machines
A core drill is a drill specifically designed to remove a cylinder of material. The material left inside the drill bit is referred to as the core. Core drills are used for many applications, either where the core needs to be preserved (the drilling apparatus for to obtain a core sample is often referred to as a corer), or where drilling can be done more rapidly since much less material needs to be removed than with a standard bit. This is the reason that diamond-tipped core drills are commonly used in construction to create holes for granite monuments, granite countertops, concrete, pipes, manholes, and other large-diameter penetrations in concrete or stone. There are many varieties of core drills, including hand held core drills, portable core drill rigs, truck mounted core drills and large stationary core drill machines used primarily in the granite monument and memorial industry. Core drill bits or core drill barrels range from 1” to over 12” in diameter and up to 48” in length. . Click here to find a GGA granite and stone machinery supplier.
