Smooth cuts
So far I've only use one out of the pack. However it cuts great and has the drill bit centered in the hole saw. Cuts a little larger then the size needed but just like 1/16 to 1/8 bigger. Easily filled the extra hole with silicone.

Worked well on 1045 steel round
Very satisfied and the price was 5 stars. Worked well on 1045 steel for a 1-3/4" diameter hole 1.5" deep in a 3" round. Of course I had to cut from each side. The first 1/2" went relatively easy considering the material. Chip clearance got progressively worse after the first 3/8". Why just 4 stars? These are metric cutters advertised as inch. The 1-3/4" is actually 45mm (1.772"). I assume all the rest are similar approximates. Does it make a big difference in my current project? No. Attached picture shows the cutter after the hole. Nothing is broken and teeth are still sharp. Also included is the plug that was removed. The finish in the hole is about the same. First 1/4" is pretty good. After that chip build up ( I cleared frequently) gave a poorer finish.

Quality cutters at an affordable price
Hole sizes are accurate and the carbide has no problem chewing through metal, wood, plastic, or anything else you put in front of it. A drill press is definitely recommended for the larger diameters.

Must have for aluminum.
Needed to drill a large hole in a custom aluminum plate. Stuck one of these in a drill press and chewed through the aluminum with very little effort. Had to run a lower RPM on the drill press because at higher RPMs, it tends to squeal quite loudly.

Durability and quality
Very high quality product. I loved it specially when I used to drill on stainless steel.
