UNIKA UR21 Ventilator Set (110/160) for Vibration

A vibration core drill with a blade shape that is ideal for hard wall materials, etc., achieving both precision and efficiency.
The cutting edge is given small vibrations and rotations, which crushes the workpiece while cutting, allowing for speedy drilling.
One shank allows easy exchange between 110mm and 160mm body sizes.
Simply turn the tightening ring to firmly set the body.
The wide contact area efficiently transmits rotational force.
The flange part is made lighter by using a new material (high-strength aluminum alloy) that is lightweight and rust-resistant.
The centre drill also has a one-touch attachment/detachment mechanism.
Mortar, blocks, bricks, gypsum boards, slates, ceramic siding boards
* Please use gypsum board and soft siding board in rotation mode.
