This is a good product at a good price. Easily cuts a through sheathing and siding. I have used primarily for cutting dryer vent, exhaust vent holes through the exterior of my house. I would recommend. I purchased this in combination with the DEWALT DW1803 Heavy Duty 7/16-Inch Shank Quick Change Mandrel (Fits Hole Saws 1-1/4-Inch - 6-Inch) a great combination.

Color Name: Bi-Metal
It is a good quality bi-metal hole saw and it cuts quickly through metal siding, even corrugated metal. It dulls very fast if used on MDF or Hardi board and other fiber cement siding. It needs a powerful 1/2" drill with anything other than metal and forget about using it with a cordless drill.

For wood and Hardi board siding and sill plates I use TCT hole cutters and my DeWalt triple speed range 18v cordless can drill a 4-1/8" hole with ease. Best I have found are the Blue Boar which cut fast and hold up well. New version of Mega TCT can even be used when there are nails which is terrific.

Bi-metal hole saws are a good bargain and good for metal and there is no point in paying any more for a ones painted a different color if all you are cutting is metal.

Color Name: Bi-Metal
I used this hole saw to chop through a 1/4" hot rolled plate as part of a welding project. Went through easily. There was a little bit of chatter that affected the final dimension. Diameter of hole was 4.1314 inches. It's still sharp and I plan to use it again.

Perfect in every way. I cut a hole thru the wall for a 4" dryer vent tube. This tough little saw cut thru smooth as silk. The hole is the perfect size for standard Whirlpool vent kits and 4" stove pipe. Guess I'm so impressed because of the crummy saws I used before. Hope this helps someone.

This is a great tool and is the perfect size for 4" duct work in your house. The edges were very sharp and ripped right trough the vinyl and the plywood on the side of my house to put in a vent for my bathroom. I would buy another dewalt hole saw if I needed a different size.
