Same summary

Bosch EXPERT SDS-plus-7X hammer drill bits, 8 mm in diameter and 200 mm in working length, in a set of 30 pieces, are aimed primarily at those who often drill into concrete or stone. Such a set makes particular sense if you need reliable and identical drill bits for a large number of repeated tasks, such as renovations, adaptations or installations. They work best in combination with a suitable SDS-plus hammer, where the length and resistance of the drill bit come into play. For users looking for versatility in different diameters or materials, however, this set is less suitable, as it is specialized for one purpose and dimension.
