I purchase these bits about 12 years ago. These bits are well made and are fine if you want a starter set. Most of the time I use them for a back-up set. The bits are too short for most of my drilling applications and I usually purchase individual bits for the jobs I'm working on. It's good for a starter set and you can decide later on which bits you need and how long.Get more detail about Bosch HCK001 7-Piece SDS Plus Rotary Hammer Drill Bit Set.
