First of all I would like to say that at around €15 I don't have very high expectations for a complete hole saw set. I usually need a hole saw from time to time and only occasionally, and I have a couple of extremely high quality hole saws that I use when I really need something clean and precise. It's a spare set for the most part and I can't really complain about that and it actually works pretty well for that. Purpose of the fishing cable and the pipeline in the raw basement. For that it was great and just what I needed. I've used a few different types of these saws over the years and I understand that using one of these specific sizes will not last long. a little. It's not a bi-metal product as far as I can tell and I imagine it dulls fairly quickly, especially if you're trying to saw hardwood and engineered wood, which is probably the case when you're using it for cabinetry etc . use . Overall, I can't rate it less than four stars for the most basic features. If you're looking for a really high-quality kit, be prepared to spend three or four times as much. But in a world of similar prices, this is definitely something to consider.
