Tips
1.The cutting material must be fixed, can not be moved, and the opening at a right angle of 90 degrees.
2.At the beginning of drilling, you should slowly contact the drilled material，do not hit the workpiece, and use a low number of rotations (the larger the hole opener, the lower the number of rotations).
3.Please don't push too much force when tighten or loosen the screw, so as not to screw the screw slippery.
4.Coolant can be added when using, attention should be paid to slowing down the follow-up speed when drilling quickly. In the course of operation, if there are anomalies or unsatisfactory chip removal, stop working and pour out the chips before working.

I used this small hole saw to drill a peep hole (viewer) through my metal front door. When through like it was butter. Excellent fit and finish on the bit and it came in a nice carry case.

I bought this drill bit to drill a hole in the front door to install a peep hole viewer. After reading reviews about the center drill bit failures, I removed the spring and then used a regular drill bit to drill the pilot hole through the door. I then used the bit assembly to drill the larger holes, drilling from the outside on each side of the door. It worked perfectly. The cuts were smooth and clean.

I had a steel door with a foam core I was installing a earl diamond solid brass peephole (which I also recommend) in, that requires a 28mm hole. Works great, took about 3 minutes, I do wish the the bit was a bit longer. The first steel panel was easy, but I couldn't reach the back side. I couldn't come in from the other side yet and get it to line up perfectly. So I had to pull the bit out of the drill a bit, more than I'd like to puncture the far side of the door with the small bit. Then I could drill from the far side of the door using the small hole as a guide.But did a quick job, nice clean cut, and it has a nice design. Just wish the shaft was 0.5" longer or to allow cutting through a 2 inch door. For a cleaner cut I recommend using very little pressure and be patient.

This is a circle-saw with a centering drill-bit; you drill a guide hole the centering size all the way through, then put this into the chuck on your drill and use the circle-saw to cut the full diameter hole from both sides. I bought this with a door optical peep-hole, so I was working a hollow-core door. I got quite lucky, of course the saw part cut perfect fit holes through both the inside and outside surfaces, but my guide-hole had hit one of the inside braces, so I had an actual guide all the way through as the circle-saw cut through three diferent interior bracing boards.

I was skeptical of this bit at first since the teeth look so aggressive. I had to drill a foam filled steel door. I was concerned that it would catch on the sheet metal and tear it. However, this bit worked perfectly. I drilled a smaller pilot hole first because I wanted to penetrate the door from both sides. I used the bit on high speed with gentle pressure and the result was flawless.

Cuts cleanly, clogs a lot, very shallow depth of cut, center drill bit is a bit fragile [mine broke day one], but they are in this setup.spring is a nice touch, but may only be useful for very thin materials.I was using it for 1/2" high grade plywood [arcade buttons] and was fine for my one use.
