Bosch Professional 7-Piece CYL-9 Multipurpose Drill Bit Set (Multi Construction, Ø 4-12 mm, Accessories for Drills with Round Shank Drill Bit Socket)

Item arrived in a timely manner and well packed.Found these drill bits to be of good quality and of handy most used sizes. Normally use Bosch or DeWalt drill bits as you get value against use rather than expense against replacements with cheaper products. These perform excellent on most GP jobs, but struggle on some dedicated applications where you need SDS or Cobalt specials, as you would expect. Not a great believer in multipurpose against specific tools these have performed better than expected and would definitely recommend and use again when required. They are handy when drilling through different materials in an application and extensively used in a recent kitchen update with good all round performance and far better than those drills sold on a certain shopping channel that are next to useless.Would purchase again and recommend for general purpose.

These are the best masonry drill bits I've used, somewhat pricey compared to other bits but well worth the money.They bite well when drilling tiles and go through brick very easily. They work well on wood too but if you're only drilling through wood I'd stick with brad point wood bits for accuracy.

Overall these are great bits, and it simplifies what you need to carry around with you. For brick and masonry these are as good as any dedicated masonry bit and maintain their sharpness well.They will drill wood, metal and plastic but they won't drill as crisp a hole as a proper bit especially in softwood, good enough for general construction but for precision work I swap back to a proper bit.

We live in an old victorian terrace made with proper London brick (if you know you know) and I broke so many drill bits in the walls before I found these, now it's a joy to make holes as these drill bits just get the job done and I've been using for 2 years with no loss of performance or loss of drill bits.

Excellent product at good price delivered in timely manner - would recommend

Handy case good quality

I don't know what the walls in my house are made off but they are tough. I have lived here for 20yrs and these are the only drill bits I have ever found that are up to the job of drilling holes in my walls. However they don't last forever.

I can't fault the drill bits themselves, they seem to go through everything. The box is a bit hard to get open to get the drill bits out as the plastic has no points where you can grip onto it to open, that said the most important thing is the drill bits and they are great.
