It offers lightning fast drilling, without breakout, and without the need for special machinery. Material from common brickwork to hard concrete (80 100mm) can now be drilled dry. A 132mm core takes only a few seconds to drill through brick and, with an expected life of over 300 holes without re sharpening, costs only a few pence per hole.
