Deltagon vibration bit (delta axis) DLS032

Used Panasonic's vibration drill driver EZ7960 (21.6 V) for mortar surface to punch holes for saddle fixing non-ravis. Use nonplastic. Very beautiful holes are available, so compatibility with non-ruggedness in which the state of the prepared hole affects the strength is very good. In rotary hammers, there are cases where the impact is too strong and destroy the mortar surface of the mating material, and we use the straight shank drill and vibration type tool. Even if this type of shank is said to be straight, it is not a true circle but a rounded triangle (delta axis), so it is easy to chuck and not worry about slipping. There is no particular problem with the discharge of chips.
