Abstract

A drill for concrete and rocks is being developed using a laser-based hybrid technique. The design locates the outlet hole of laser beam and drill blades on a common rotational axis. The laser beam weakens the concrete, and the blade breaks the weakened layer. The target performance is a drilling speed of 30 mm/min at a sound level less than 70 dB using 1-2 kW laser power to produce a φ20 mm × 300 mm hole.
