- Easy to use
- Makes a perfect hole the size you need (the step feature makes it easy to increase size a little at a time)
- Works in seconds
I will never again be without a tool like this!
I already had a dead bolt size of 1" 5/8. Old lock. So a hole saw would not work. This cut a 2" 5/8 hole like butter. Very sharp and no heat marks.
There are a few downsides, but I consider them worth it for the price. First, the size markings inscribed on the bits are of varying quality. Some are more difficult to read than others, and they don't always line up with the steps, meaning I occasionally have to count down from the top to tell which marking goes with each step. Also, the case is in no way aluminum. It's part plastic, part imitation-plastic, but with a metal latch and hinges. It's actually a very nice case in spite of the materials, just don't expect it to take a lot of abuse.

Not sure I will ever have a use for this large of a hole in metal again, but this did the job for what I needed it to!
