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

Rated 5 out of 5 by from Excellent. Great tool... from body panels to 6mm steel plate it cuts great. Does snatch a but but not as bad as a twist drill bit of the same size

Rated 4 out of 5 by from Good addition Very handy thing to have rather than a 20mm and 25mm holesaw which blunts far quicker. Also the best way to change a 20mm to 25mm hole. Could be better by having it go 4mm up to 32mm instead of having to buy the set

Rated 5 out of 5 by from Spiral flue step dril Good quality step drill for a great price compared to other makes and models. Been using to drill 20 / 25mm holes through 1mm Galv trunking and socket boxes etc for a while, nice keen cutting edge, and seems to be made from high quality, hard wearing tool steel.

Rated 5 out of 5 by from Excellent Sceptical as I had to drill a 25mm hole through a car chassis however it went through like butter. Best bit of kit Ive bought in a long time.
