Efficient and energy saving This device can turn an electric hammer into a water drilling machine in seconds, with fast flowing water that cools the drill and clears debris, saving time and effort. Simple operation The pure copper water injector is easy to operate, and the water flow can be conveniently adjusted to suit different materials and drilling conditions. Multi functional A single water drilling machine can perform the functions of both an electric hammer and a water drill, making it a practical and versatile tool. Durable and reliable The pure copper valve, made from material, ensures reliable and stable long term use. Compatibility and performance Designed to attach to an electric hammer to enable water drilling, promoting better dust control and chip evacuation during drilling. Material and build Key components include a pure copper water injector and a pure copper valve, built for durability and consistent performance. Use scenarios Construction and renovation: Drill concrete or masonry while injecting water to minimize dust and improve cooling and chip removal. Home improvement and tile work: Create holes through walls or tiles with controlled water flow to cool the bit and flush debris. Plumbing and electrical installations: Drill precise holes for pipes or conduits with reduced dust and enhanced drill efficiency. Notes For results, adjust the water flow to match the drilling material and bit size. This device is intended to extend the capabilities of an electric hammer by enabling water assisted drilling.
