Blue Spot 19512 Tapered Guide Drill Bit 10 x 200mm

Diamond core drill bits are suitable for drilling most common building materials such as concrete, brick paving slabs, asphalt, limestone, clay bricks and aerated block. A diamond corer will cut clean accurate holes producing exact size holes with almost no break out. Core can be removed in one piece avoiding the need for making good by a brick layer or plasterer. Unlike traditional carbide tipped core drills diamond core drills require no hammer or percussion action when drilling. When boring a hole with a diamond corer, the corer is mounted on an arbor. The arbor may have an SDS or a hex fitting appropriate to the drill or chuck used. In order to centre the corer a tapered drill bit is used to centre the boring hole and stop it wandering.
