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

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

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.

I bought these because I thought there were Kobalt.

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

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.

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.

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

not very sharp cutters. ⅜ shank not as sturdy as other brands with 7/16 shank. once the cutter is screwed onto the shank and used once, the cutter is practically impossible to unscrew from the shank and change. overall a sub-par tool that im very disappointed to have bought. will buy the other brand, and just accept my loss.

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.

As expected
