Hole Saw Kit, 17 Piece General Purpose 3/4 to 2-1/2 Set with Mandrels, Bi-Metal, Durable High Speed Steel (HSS). Fast Cut Clean, Smooth and Precise Holes Through PVC, Metal, Wood, Plastic, Drywall

Pretty good

I used only the 2.5 saw and the treads stripped out after 5 holes through 3/4 plywood at a slow speed. Had to weld the arbor to the saw to finish drilling the holes I needed

Teeth aren’t very sharp and the bit was not perfectly round. They were slightly off and made drilling a pain!

Worked well on thin metal such as sheet metal of furnaces & other HVAC equipment

My dad loves this

very happy,used to cut a hole in front door for dead bolt

As expected

Couldnt make a hole in thin metal. Was a pain to take apart, even with a pry bar. Teeth were worn down within 5-8 minutes. Couldnt even complete making 1 hole.

Needed this for a kitchen project. It never arrived so I had to improvise. Looked like a good set based on reviews.

Bummer, 30 days after purchase. The teeth on the saw, just disintegrated .
