### ⭐⭐⭐⭐⭐ Nice and easy way to drill a few holes here and there in metal real fast
*by M***X on September 16, 2022*

The media could not be loaded. My Desktop PC case didn't have enough ventilation. Front side of it was basically a metal sheet with no holes at all. I got this fancy drill bit and used it with a CORDLESS drill.. Now that I think if it, it would've worked slightly better with more powerful 750W corded drill. Main issue is that when I got to about 75% of the metal sheet cut - the drillbit was getting stuck in it and the metallic case was vibrating violently. So I had to really keep it held tight. It would've not been an issue with a more powerful tool, or if I had a workbench to secure the PC case.Ultimately the hole is there, not 100% perfect, but looks good in the final product.Considerations:- it works even with a cordless drill- the hole for PC case fan looks OKAY- it would've worked better (less vibrations, more precise cut) with more powerful corded drill

### ⭐⭐⭐⭐⭐ Worked good on fiberglass

Worked great in fiberglass

### ⭐⭐⭐⭐ Served its purpose almost perfectly.
*by S***S on June 30, 2023*

I needed 3 holes in 3/4" double-sided oak veneered plywood. I wanted to use my Dewalt quick-change mandrel.I drilled 1 test hole then the 3 finish holes. The saw did an excellent job for me. There was no chipping or tear-out on the finished side; however, on the back side there was significant tear out. I didn't notice any difference in speed on the 4th hole. It cuts pretty quick for a hole saw in 3/4" plywood. The paint started pealing off on the 3rd hole but that's no big deal for me. I highly recommend using a small pilot hole before using the larger bit that comes with it. I didn't drill a small pilot hole and the larger bit skated a little off of where I wanted it to be.The mandrel threads are not perfectly square with the surface of the saw. This isn't a big deal if you're using the included mandrel. For me the Dewalt mandrel threaded fine until the last 1/8" or so. I used channel locks to finish threading the saw. This is when I found the out-of-square mandrel threads as the saw doesn't sit flush on the back side of the saw. It's also when I discovered the holes for a quick-change mandrel are not spaced properly for my Dewalt mandrel. The 4 holes should be standard for quick-change mandrels. I had to use a hammer to get the mandrel pins into the saw holes. The pic shows the holes are just a little off from where they should be causing a tight fit of the pins.I've never used a spring on a hole saw but it works great. All 4 remnants popped out as soon as I was through the plywood.All in all the hole saw worked great for me. It just took a little effort to use my quick-change mandrel.
