Storage box made of plastic with 5 Heller ProStone masonry drills: 4, 5, 6, 8, and 10 mm. The ProStone masonry drills drill quickly, well, and reliably into stones and are very suitable for use in cordless drills. The 4-way spiral quickly transports drill dust away. The use of a robust carbide plate ensures a long service life. The ProStone masonry drills are suitable for masonry, clinker, aerated concrete, natural stone, and sand-lime stone. These drills can also be used for hammer drilling; however, the Heller ProXtreme concrete and natural stone drills are better suited for that purpose. The drills have a round shank, making them suitable for quick-change or keyless chuck systems. These storage boxes often have a crack in the transparent lid, so we can only exchange boxes with significant damage for free. This applies, for example, to boxes with a broken lid.
