This was purchased to enlarging a 1" hole in a 7.5kw electric heater for a larger grommet and it worked well.

I bought to drill 2 1/4 holes in a metal cap. This unibit worked great and was a reasonable price. Highly recommend it if you need a big unibit that has good quality

Great price, A- cut. It takes a second to get used to. You'll need a proper drill as an impact wrench will neither fit the bit, nor cut properly. This wants a steady, medium, high torque turn. An impact driver will make a sloppy cut in plastic. However with the proper tools, this works well. Its 'stepping' is discreet, meaning it jumps from one diameter to the next with in between diameters not as clean as the diameters that are written on the bit.

Works pretty well and plenty sharp. Used on aluminum to open up a 1 inch hole to about 2 inch worked great.

I used this on thick steel even though it is not designed to be used for this and it held together like a champ.
