HSS Screw Point Self Feed Wood Auger Drill Bits

Impact drills can be used for natural stone or concrete. They are universal, because they can use either the "single drill" mode or the "impact drill" mode, so they are basic electric tools worth choosing for professionals and hands-on workers. The electric hammer works by rotation and hammering. The single hammering force is very high and has a hammering frequency of 1000 to 3000 per minute, which can produce significant force.

The impact electric drill is an electric tool used for drilling holes on materials such as bricks, masonry blocks and light walls, which is mainly used for rotary cutting and has an impact mechanism that relies on the operator's thrust to produce impact force. Take off the overhead pin to make the fixed disc rotate with the moving disc without impact. It can be used as an ordinary electric drill.
