I recently purchased a Hole Saw from the Hole Saws & Accessories category in Cutting Tools for an industrial and scientific project. Thanks to my knowledge gained in practice I must say I am impressed with the durability and precision of this saw. The bi-metal design easily cut through steel without dulling the teeth .The only con is that it is a bit more expensive, but the quality outweighs the cost. Overall, a great investment for any serious DIY or industrial project..
Pros
Durable bi-metal construction lasts longer than traditional hole saws
This is a quality tool from a well known brand that was just what I needed. The seller was a very fast shipper and would happily buy items from him again.
