Review on High-Speed Titanium Nitride Coated Spiral Grooved Quick Change 4 Flute by Marcus Rash

I just got Starlink when they arrived so I took them to the roof and used them to drill holes in a steel pipe to install a satellite dish. They worked great! I didn't even oil it or anything but it didn't get hot at all. I didn't push it too hard or anything, but that's what I want it for. If I need to drill something, I don't know exactly what size hole I need, and I don't want to lug a bunch of tools onto the roof. It fit perfectly in my wireless driver. It claims to remove burrs as it moves. I suspect he messed up the top of the hole a bit, but the back was just as sharp as any other drill. I used one of those rotary cutters on the hole after drilling it. The steps on the bit work well. It's not just a cone. he drills a hole, then he starts drilling the next size, and the measurements are marked to the stop on the inside, which must not be erased. We have not checked the dimensions as they are not important for most of our projects.
