Through trial and error I found that this cutting depth accessory is the perfect addition to my hole saw collection. It allows for efficient and accurate cutting, MAKING my job easier and faster than ever before .The durable material ensures long-lasting use, and the easy-to-read markings take the guesswork out of measuring. The only downside is that it's not compatible with all hole saw sizes, but for the ones it does fit, its a game-changer..
