Size not stated

Hole saw advertised and pictured as 4". The one I received is clearly marked as 3 and 15/16 inches. To make matters worse, it is actually measured from the caliper at 3 and 7/8 inches. The lights I bought them for just don't fit the holes. The good thing about this saw is that it is VERY sharp! But combined with a simple screw attachment mechanism, this can be a dangerous combination. As another reviewer suggested, consider chaining them together if you need to use them. I'd recommend skipping…

Pros
  • Absolutely amazing!
Cons
  • Not bad but...

The thread connecting the blade and cartridge is not tightened. Unscrew and risk of injury!

The blade itself is pretty decent and cuts through drywall quite easily. HOWEVER, and this is very important, the threads holding the blade in the chuck are not tightened. If you're using a saw with a drill and you meet resistance, the blade will rebound and the saw will spin back free of the chuck, like a Bey-Blade top. I was on the stairs cutting holes in the ceiling and it almost flew onto my hardwood floor. I caught him but got a small cut on my fingers. It could be worse. Don't buy it…

Pros
  • Nice package
Cons
  • Can't remember

Great for single or dual use

Had to cut a hole in the tub panel for a valve. I only needed to make one cut, so I didn't need a strong one, but I did need a safe and precise one. That was excellent. The hole is true to size and well cut. I don't know how it will behave in wood, but everything was fine in the acrylic edge of the bathtub. I already had a smaller diameter hole saw with a central hub with locking pins, so I used that in place of the hub that came with the kit. these (without locking pins). The supplied socket…

Pros
  • Consistent test results
Cons
  • Could have chosen a newer model
