Rated 4 out of 5 by 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. 1 Jul 2015
Rated 5 out of 5 by 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 14 Jun 2015
Rated 4 out of 5 by Perfect for the job Having to drill holes through steel and these cope with the job admirably with constant use on drill press. Seem to last pretty well and go through steel without a problem 9 Apr 2015
