Rated 5 out of 5 by from Amazed I needed to make a 40mm hole in the side of my narrow boat to fit an exhaust skin fitting, 6mm steel. I was amazed that this cutter went through it relatively quick using a drill driver. Nice clean cut and the cutter is still sharp. Good price for what it did.

Rated 5 out of 5 by from Good Service I bought a 40 mm hole saw blade a couple of days ago for my Bosch hole-saw system!. I’m only ever likely to use it to cut wood ... so have no concern about its performance..... but I haven’t used it yet. My comment; therefore is about the Service that I received. I bought it online using ‘Click and Collect’ ... it’s the first time I’ve used that system. Having received confirmation of purchase; I went to my local Screwfix Shop and found that the saw-blade was ready for me to collect . No problem at all. In addition the staff in the shop were most helpful!

Rated 4 out of 5 by from Bosch holesaw - a good system. Having been after a holesaw system for a while after my cheap Stanley one failed I did some research and happened on the Bosch 'progressor' system. The clear advantage of being able to change the bits makes this an absolute doddle to use and switch out. Being able to change the pilot bit and the shank (for SDS, hex etc) also makes this particularly user friendly. The range of different diameter bits makes it ideal for any job. Whilst I haven't put it through its serious paces yet, on first use it gives a clean, neat hole and promises to do so for a good while to come under moderate use.

Rated 1 out of 5 by from Dont buy Bought this to replace my old Bosch 40mm bit. Had my old one for quite a few months and used it for drilling through metal stud work in newbuild. This one lasted 3 weeks before all the teeth had gone. This is a new design and wouldn't buy another. Steer clear.
