28mm 200mm 140 Mm 2 Inch 4 Inch Masonry Core Drill Bit For Hammer Drill
Definition
A core drill is a drill specifically designed to remove a cylinder of material, much like a hole saw. The material left inside the drill bit is referred to as the core.
Core drills used in metal are called annular cutters. Core drills used for concrete are generally called Diamond Core Drills and are water cooled. For drilling masonry, carbide core drills can be used.
Core drills are used frequently in mineral exploration where the coring may be several hundred to several thousand feet in length. The core samples are recovered and examined by geologists for mineral percentages and stratigraphic contact points. This gives exploration companies the information necessary to begin or abandon mining operations in a particular area.
Core drills come with several power choices including electric, pneumatic, hydraulic (all of which require power sources, such as a generator).
Application: tile , glass, granite slab
Machinery: Hand held drill, drilling machine
