I needed a bi-metal hole saw to drill through an exterior door so I could install a deadbolt. This did the job perfectly and cuts through metal without issue. I enjoy the organization that the case provides and easy of use when changing hole sizes. Great little kit.

The product came in a plastic case which is nothing closed to a high quality brand. There is no brand on the case and the quality of the case is what you can find in very cheap products. I haven't used the hole saws and I'm not sure if they perform well but the case is a huge disappointment.

Great price for a Bosch set.The fact it’s also designed for other materials other than wood is an extra.

I drill holes in food-grade plastic 55 gallon drums for water collection. I luv that the attachment can be used to drill holes in plastic, wood and metal. Highly recommend.

You need a drill which can take a the very large diameter drill bit for the three large hole saws. The smaller three work with a smaller bit, which were the only ones that fit my drill.

I could not locate the size of the mandrel on the product page and ordered based on all similar products having a 3/8 compatible mandrel. So it didn't fit my drill: this one is actually a 7/16 mandrel.The front of the packaging is one of the product images, but not the back where all the relevant dimensions were clearly indicated.The product is probably great, but I never got to use it.

Utilicé 2 medidas de corte para instalar tubo conduit de 1/2" y 3/4", obteniendo un resultado satisfactorio. Lo importante es seleccionar el tipo de sierra adecuada para el material al que se le realizará el corte

Used these on some plywood and drywall, worked very well. Easy to use, sharp, and effective. Bosch is great and trustworthy and this purchase is another example of that. Good luck!

Typical Bosch quality. Be aware there there are only six sizes. The case seems to have been made for different saws. Several of the indents are too large. Other than that, there are two sizes of arbor and they fit the standard sizes. Because I got this on (a bit of a ) sale, and I use many hole saws in my business, I think that this set is a good value. Having both arbors is a large plus. You can just add on other sizes of saw as you need them.Warning - if you are not familiar with hole saws, they can be dangerous. Use slow speeds, Never tip and hold tightly to the drill.
