Review on 🔪 Klein Tools 31872 Carbide Cutter Blade by Flavio Scarola

Good set of hole saws. The case has a very sturdy feel and comfortably accommodates all three sizes of bits with an additional slot for a spare guide bit. The crowns themselves are brilliantly designed. Love love love the ejection spring built into the pilot's crown. This allows me to drill from one hole to the next instantly without wasting a second. They also have a built in stop or flange to prevent accidental over drilling. Klein seems to have thought of everything when it came to the design. The only real problem I've had so far is that I thought the 1-1/8" hole saw (commercial size 3/4") died prematurely. The carbide teeth have already broken after moderate use and I try to be as gentle as possible to prolong the life of the tool. Got a replacement from Home Depot and so far so good. If you are someone who works with a 12V electric drill, this will most likely solve this problem. The convenience of this setup is hard to beat. I also have a set of Klein knockout ratchets which I find to be more reliable and allow me to work better. However, for this quality for less than 1/3 the price, you can't go wrong.
