REXBETI Double Headed Sheet Metal Nibbler, Drill Attachment Metal Cutter with Extra Punch and Die, 1 Cutting Hole Accessory and 1 Step Drill Bit, Perfect for Straight Curve and Circle Cutting (Gold)

I am a Gunsmith in Florida and a client had a gun that needed a firing pin, one of those great big flat ones that haven't been made since 1940. I saw this nibbler and, though skeptical because of price, I bought it expecting it to fail on first cut. I put it into my drill and locked a piece of 16 gauge sheet metal into my vice and, fearfully, started to cut, and it didn't jam or stop!!! I kept on cutting until I had the entire firing pin blank cut out with absolutely NO problems. Then I cut three more because they can be used in other models of this firearm as well. The cutter did a great job going through the 16 gauge metal, but if you are going to be using it for long periods of time it gets VERY tiring because it tends to want to wander and you must correct for it.This is a great tool and I would recommend it for those who need a nibbler for occasional use.

I’ve got several different attachments for cutting sheet metal, but none of them beat this one. It does all that and then some. Very excellent product, and it will straight up surprise you. There shouldn’t be anything else out there except for this. I found it more useful than tin snips and cut off wheels, rolling attachments that you put on your drill. These things kick butt,, turn around and spit out a few teeth, laugh at you, and ask, is that all you got? These things are bitching, and you know you will have been had because they work so hard, they make you look like a wuss.

First, I was very impressed by the packaging. It came in a nice storage case with all the attachments. I did not have a drill that would run at the suggested RPM, mine were all slower. This may have had an affect on the performance. I bought this for cutting the new panels on a steel roof. When I was cutting the flat or near flat, it cut fine. When I had to go up or down it tended to not cut so fine. I ended up cutting some of the areas with a reciprocal saw (not as good a cut). A friend brought over a metal cutting blade for a circular saw and although it was a lot noisier, it was a lot faster and no toenail clipping to worry about. The clippings are a hazard for people and pets and they can get tracked into the house and damage floors. I also used the circle cutting guide. It worked well on the flats and not so well going up and down the ribs. I now know the limitations and will not hesitate to use it for the right application. Overall, I think it was a good investment

I've had this since 2020 and I still love it, has been an amazing tool, even got stolen for a couple months and was recovered I was so happy. I've used this in body work to cut out patches. Great tool couldn't be more impressed for the price.

This little critter does a good job as described. Seems simple and pretty well built. I used it on 16 ga. steel electrical panels and it cut very well. The cuts were clean with no burrs. It is a bit messy, sending chips about the workbench. A couple of notes; Use oil on the cutting ends. Just a drop or two, but it will cut better and last longer. Practice your cuts on some scrap metal. It's tricky to freehand your cuts and the line you drew is covered by the cutting head. Good product for the price and the right tool for the job

Used freehand and with the circle cutting jig. Works great cutting 26 gauge galvanized steel ducts. Excellent value for its speed and accuracy. Used with a cordless 18V Dewalt DC759 on higher speed setting (it's very slow on speed setting 1).UPDATE: reduced from 5 to 3 stars after the hole-cutting accessory broke at a weak weld. Thankfully, I was on the last hole, so I could freehand the rest of it. I used the hole-cutting accessory for about a dozen 6"-10" holes in 26ga steel before the tip of the insert pin broke at the weld. While it was working, the hole-cutting assessor worked great, easily making perfect circles.

I was surprised by how well this cut through the metal on my metal building addition. It takes some practice to get semi straight cuts but, otherwise, I was pleasantly surprised.

So I used this rarely at work for cutting into things without starting a fire. Super useful on stuff where tin snips wont do itBut recently, I had a cheap electric safe at home stop working. Key wouldnt even open it. I had my car titles in there, and couldn't get in there with an angle grinder without hurting them. So I drilled a hole, put this in, and cut through the 2mm thick steel wall, the entire way across the back. I got everything back out safely and found a bolt came loose and jammed the lock mechanismAnyhow, I've run this through stainless, painted mild steel, aluminum, a section of copper, nothing has stopped it or dulled it. I'm on the original blade, though I haven't done a TON of cuttingNow, this makes an absolute mess. It cuts crescent moon shapes out of metal. They are especially sharp and pointy. They get everywhere.The main benefit to me is no sparks. Otherwise another cutter will be faster and more accurate. An angle grinder will cut straighter. I suppose if you really took your time, got it JUST right, drew out a line, youd cut nice and straight. Otherwise it's too easy to deviate
