"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?"
"Used this to cut 4 holes in the plastic bumper and the steel bumper behind on a Range Rover. Used a slow speed on the drill and had no problem. I'm sure it would cut many more holes - I'm impressed, for the price - cant beat it."
"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."
