It is intended for users who need a powerful tool for larger holes in hard materials - these can be craftsmen, builders or DIYers on larger renovation or construction projects. The main advantage is the ability to efficiently and quickly drill large holes where conventional drill bits fail due to their diameter or length.\u003c\/p\u003e\u003cp\u003e Due to its larger diameter and extended working length, it enables penetrations through thicker walls, foundations or massive elements, which is often necessary when assembling installations or laying cables.
