Rated 5 out of 5 by from good cutter had one of these cone cutters for a good few months used in wood, metal and plastic and has been great, just got two more when they were on an offer although wish i had noticed before now that they do one that goes up to 20mm which will be better when making cutouts for conduit adaptors etc. would highly recomend these

Rated 4 out of 5 by from Versatile cutter I use it to cut a 24 mm hole into a stainless steel sink. The tip is not very sharp and I had to mark the centre properly first. It cut the hole in seconds and the in build de butter really works. Well done Erbauer.

Rated 5 out of 5 by from Good Product Used to cut a 26mm hole in a metal water tank. No pilot hole need, just use the tool. Need to keep the speed up otherwise it catches. Really quick to cut through. No jagged edges. Good piece of kit
