Bosch HCK001 7 pc. SDS-Plus® Bulldog™ Rotary Hammer Bit Set

These bits are of high quality and are very sharp. I used another brand bit and it could not do the job. Theses bits are sharp and make drilling into concrete very easy

Product works as intended. Definitely will buy again.

These are super durable and work great going through brick and concrete.

Needed to drill some holes into very tough concrete and needed to step things up from a regular hammer driller. So, I ended up getting an SDS Plus rotary hammer that makes super quick work of concrete holes. I chose SDS Plus because I couldn't ever see myself drilling holes bigger than 1" in diameter. I also wanted a set of shallow concrete carbide drill bits that I could easily throw into the tool box. This set has worked a treat so far. I have drilled many holes back to back without any damage to any of the bits or the carbide end. The flute design also does a great job at removing all the dust from down in the hole.This set comes with 5/16", 3/8", 1/2", 3x (2 long, 1 short) 1/4", and 3/16" bits. As long as your rotary hammer supports SDS Plus bits, these will fit just fine. Would highly recommend!

Excellent item that made a great gift that does the job.

These are some bad boys. Thinking these will be a serious drilling exercise in concrete. You need the right tools to do a good job. Will follow up after use.

Muy buena las brocas lo recomiendo, perfora como si el concreto fuera de papel muy buena.
