I am very happy with this purchase. I bought a similar set from the store and found one similar for the price but not the features. What sets this set apart from others is that hole saws can also cut metal and can be used for jobs such as cutting holes in backlash-free electrical boxes if required. Given this opportunity, I decided to purchase this kit both for its cutting versatility and for the wide range of bits available for the various construction projects I have at home. I have to say that these hole saws do a great job simply because they are made to cut metal. They do woodwork with ease and get the job done without much of the wobble I've had to use with saws made just for wood and drywall. On top of that, the biggest benefit of this set is that I now have all my hole saws in one handy set and no longer have to rummage through my 'wooden tool box' trying to put together a drill press and a hole saw they are needed!
