Excellent carbide countersink, sharp cone drill (easy to change. Order a few extra to keep them handy) and reasonable price. I will never look anywhere else. The only thing I can object to is that the same qualities that make it durable and really sharp make it prone to breakage unless you straighten or bend it while the drill bit is in. So if you do a lot of odd angle drilling, in tight spots where you don't have good access, you may not need a carbide hole saw.
