Bi-Metal Holesaw 20mm
This was used to make a dozen holes in mild steel, a task it accomplished with great ease. I had wanted to make even more holes, but my (ancient) drill expired in a cloud of smoke as it was not really used to producing the required torque. Nevertheless, a job well done. As to longevity, who knows?

Out of true
Bought this with an arbour for a one off job and although it worked, it was a bit of a struggle as the arbour wasn't concentric with the holesaw. Not sure if this was the fault of the arbour or the holesaw. The result was an untidy and slightly oversized hole. OK for the occasional job where accuracy isn't needed but not good enough for precise work or more regular use.

Not worth the money, drilling its first hole in a metal back box, not even half way through and all its teeth had worn away - not broken but worn away

It's a hole saw
Very good for wood, but don't use on masonry. I tried and it deteriorated quiclkly.
Very good price
