As someone with experience in Industrial and Scientific field i was disappointed in the performance of this brand's Hole Saws AND Accessories .Despite claims of durability, these tools were loud and didn't last as long as expected. The only pro was the ease of use, but that doesn't make up for their lack of quality. Thanks to my knowledge gained in practice, I would not be purchasing these tools again..
Pros
Reliable and high-quality cutting tools
Cons
Require frequent sharpening to maintain performance

For my one time job of cutting about 24 holes it was perfect and inexpensive. For a one time job it should suit your needs, if you plan to use it every day you can choose one of the more expensive ones or buy…
