My dad loves this

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.

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.

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

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

Pretty good

Great value for money Great product cuts very clean and smooth

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!

Hood to have . Not heavy duty
