I love this product and have been using it continuously for 2 months. As long as you know how to drill holes, they work great. I use them effectively and have had no problems. Put on safety goggles and mark holes, this tool will increase your productivity by 25%. I don't understand anything under 5 stars.
These bits used to last a while. Now they don't even cut a hole. I used a 1-3/8" drill bit and before the hole was cut the drill bit broke off. Someone at the factory didn't tighten the set screw properly and it rounded the drill bit. Now the hole saw just spins on the bit .A complete waste of money.
This is a great hole saw for an electrician as they don't need to carry a drill to have a real hole saw. The set screw cuts into a second hole and the chuck rotates freely. So if you don't have access to a welder to weld a chuck to a real hole saw, save your money. When soldered together they become absolutely cool. I can keep all 3 in my tool belt and just carry your punch. Would recommend if you know how to weld.
