Erbauer Spiral Flute Step Drill Bit 6-30mm is rated 4.7 out of 5 by 9.
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.

Rated 4 out of 5 by from Pleasant surpise The old jockey wheel died on the trailer and the heavier new model had different bolt centres M16. I bought to widen one hole and make a new hole. I widened the hole in 4mm mild steel no problem and I thought I would need a pilot hole for the new one. I started without a pilot and was surprised when it drilled through and began making the M16 hole without much effort. I admit I was using a cutting oil to keep it cool whilst drilling. I will use it for drill electrical boxed for conduit connections etc and see how it goes but for the money okay so far, a better plastic enclosure would be been better as it won't last as long as the bit in the tool box and thats when the edges will get destroyed.

Rated 5 out of 5 by from Does what it says on the tin! Very easy to use even for a DIY-er using a hand drill Bought for 1 job but I'm sure it will be handy many times in the future Much better at the stepped sizes than a cone cutter
