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

My dad loves this

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.

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

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

Hood to have . Not heavy duty

Pretty good

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.

Great value for money Great product cuts very clean and smooth

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.

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