After I put it to the test I was thoroughly impressed with this diamond hole saw .It cut through porcelain tile with ease, leaving a clean and precise hole. The saw felt durable and well-constructed, and the included arbor made attachment to my drill effortless. My only minor complaint is that it tends to produce a lot of dust, but thats to be expected with this type of tool. Overall, I highly recommend this hole saw for anyone in need of a reliable and efficient cutting tool..See full review
