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

Nice little set

These were so badly made ,they wouldnt cut. Most were not even close to round, and welds werent lined up. Unuseable, waste of time and money. Avoid these.

The material is weak. I made 3 holes on metals studs and the teeth are gone. I couldn’t remove the bit out of it.

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

I bought these because I thought there were Kobalt.

Using it on thin aluminum and these cut horrible. Bit constantly falls out despite realigning and tightening. Save your money and buy a Lennox kit.

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

My dad loves this

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

Good deal fir the money. However, extremely difficult to take apart once you have drilled your hole. I use two pipe wrenches to separate the cutting bit from the drill bit.
