Review on Durable Bi Metal Drilling Aluminum Stainless by Patrick Ewing

Based on our own experience, this hole saw accessory did not meet our expectations. While it claimed to be durable and suitable for drilling through aluminum and stainless steel, we found that it struggled to make clean cuts and easily became dull after just a few uses. On the plus side, the price point was somewhat affordable. However we would not recommend this product for those in need of reliable and efficient cutting tools. .
