We recently picked up a hole saw from this brand and it has proven to be a great addition to our industrial and scientific cutting tool arsenal. Based on our own experience, this hole saw is durable, easy to use, and has a fast cutting speed. The teeth stay sharp after multiple uses, which is a major advantage. However, we did notice that it can create some vibration when in use, but it is minor and does not affect the precision of the cut. Overall, we highly recommend this hole saw for anyoneβ¦
