BOSCH HCK001 7 Piece Carbide-Tipped SDS-plus Rotary Hammer Drill Bit Set with Storage Case

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.

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!

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

I subtracted a star because 3 of the 7 are 1/4 inch so you are actually only getting 4 sized. I've looked at the description and can see they kind of explain what is included, but even knowing what is included I find it very hard to know what's included. On the other hand, they do include a VERY good case to keep them in. The quality is very good. It only took 10 or 15 seconds to drill an inch and a half 5/16 hole in red brick using a cheap drill.

Que hay seguridad

I'm surprised they work well

BOSCH company has produced good quality electric drillers and drill sets for concrete. This drill set is very strong and durable. I used this drill to drill 16 holes on concrete for my porch hand rails, it took very small effort to compete the job. Would buy again and of course would recommend to others.
