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

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.

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

Pretty good

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

My dad loves this

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.

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.

Hood to have . Not heavy duty

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