Makita 8406 Diamond Core & Percussion Drill — 110V (850W)

The Makita 8406 is a heavy-duty 110V diamond core drill built around an 850W industrial motor, capable of driving diamond core bits up to 152mm diameter. Designed for plumbers, electricians, general contractors, and the hire market, it combines percussion action for pilot holes with rotary action for dry diamond core drilling — delivering clean, smooth holes through tiles, marble, concrete, and brick.

A built-in safety torque limiter protects the operator if the core bit snags, making it one of the safest and most practical core drills available for site use. Supplied complete with carry case, chuck key, and side handle.
