The bit set is rounded off with a 60 mm long impact-resistant bit holder equipped with a stainless steel sleeve. The E 6.3 shank of the bit holder is made from robust, durable carbon steel with a strong magnet that facilitates bit guidance and allows for smooth operation. The impact-resistant masonry drill set is stored in a practical storage box that provides organized storage space and quick access to the Einhell tools. The sturdy auto-lock clip closure ensures secure sealing of the box, while the transparent lid offers a clear view of the contents. The 33-piece bit set from Einhell is compatible with all standard drill chucks and bit holders in commercially available impact cordless screwdrivers and drills.
