The utility model relates to
building construction tool technical field especially, a dustless
trepanning device for
ceramic tile
trepanning, solve the problem of the
sponge of
fixed position as main
dust fall component in prior art, its dust
absorption capacity is limited, in the process of continuous high -speed drilling is easy to rapid saturation, lose
dust fall function, lead to a large number of dust overflow, pollute the construction site, and endanger the
respiratory health of operating personnel, the
trepanning device includes cutter and the
drill handle connected at the top center of cutter, the cutter outer ring top is rotatably connected with the mounting ring plate through the rotating part, and the mounting ring plate one side is equipped with the holding component. The utility model is through setting up water mist spraying mode and carries out continuous
dust fall, effectively restraines dust
diffusion, avoided the problem that the
sponge is easy to saturate and fail, improved dust fall efficiency and
operation safety, stable structure, convenient to use, satisfy the actual demand of
environmental protection and occupational health in the
ceramic tile trepanning operation.
