Description

• To expand the hole horizontally (if needed), making the entire size of the hole bigger (350 mm).

• Use: First pre-drill the hole with the normal augers, after then the hole diameter can be expanded by fitting the expand drill bit. It is enough if every second or third auger is the expand drill bit. For example, for a 10 meters lenght hole, you must first pre-drill with 10 (200/250 mm) normal augers, then you can replace every second or third auger with the expand drill bit and repeat the drilling process for the larger diameter (350 mm).
