Metal Hole Saw 2-3/4 Inch / 70mm Hole Saw Drill Bit, Tungsten Carbide Tipped Hole Cutter with Titanium Plated Pilot Drill Bit, TCT Hole Saw for Stainless Steel Sheet Metal Brass Aluminum

Great tool. This hole saw punched through the side of my vehicle almost as fast as a bullet. It is sturdy, well made. and sharp. In all fairness though, it not like today's autos are particularly tough. It is worth the money I paid.

My new peephole project required this unique hole saw size unavailable in my too sets. It was a bargain arrived quickly and worked well to convert a preexisting doorbell-camera hole into a peephole. A little tricky with my limited skills.

I needed this hole saw to cut through a metal door to install two deadbolt locks. It worked perfectly well for what I needed, but I would imagine it doesn't have a ton of additional cuts in it. The quality was sufficient for my use, and the price surely was right, but if you need to make holes over and over, I'd recommend shelling out the big bucks for a higher quality tool. For my use, I'd surely purchase this again.

Good product

ordered to put in deadbolt locks in steel clad doors. Worked well at cutting though the steel.

Simply AMAZING!!! Cuts steel like butter!! Real life saving hole saw!

This product is well made and has a spring built into the tool. It cuts great and the price is good also.

Had to make a smaller hole 1-1/8” in an RV. Put piece of plywood in back. Then able to adjust the pilot drill out as far as I could. Drill got into plywood and held drill steady for a perfect 1-1/8” hole. Would be hard to do with other hole saws.
