Bosch T118A3 3-Piece 3-5/8 In. 17-24 TPI Basic for Metal T-Shank Jig Saw Blades

They work well

This is for the 36 tooth "stainless" version blades. I was glad to see that Bosch is still making a very fine tooth blade for thin sheet metals. The only other I can find now is from Diablo - those are usually great blades but those are longer than this Bosch model, and more expensive.In addition to being shorter, these Bosch blades also use a cobalt HSS for the teeth, which is great for all steels but especially helpful for stainless. Much nicer to have these very fine teeth - less chattery than 24T and even a noticeable difference from the 30T that Diablo has. Makes quick work of stainless sinks and even works well on 14ga aluminum where it's nice to reduce any chatter since the aluminum can bend easily if you oops (a bit fine to prevent chip clogging but wasn't a problem for me). I wouldn't mind seeing these in something besides wavy set but they work very well. A shorter one would be great, too, but easy enough to trim them down for when that's helpful.

I'm using these T123X blades in my Bosch jigsaw, which works perfectly after about a decade. My latest application is cutting 1/2" acrylic sheet which can be non-trivial. My wood jigsaw blades melt the acrylic and create a mess whereas these metal blades with up to 24 TPI provide a nice clean cut. It's surprising that metal blades work the best on acrylic.Highly recommended and (currently) at a great price

If you only have a little cutting to do and you are not in a hurry, these blades will do the trick.A few things:#1. I had to grind off about 1/4" from the end and the tabs. My very old, but still working great, Craftsman jig saw's motion moved the blade clear of the material. This cased me to push forward were there are no teeth. By shortening the blade I as able to keep the teeth in full engagement regardless of where the saw was on it's stroke.#2. I had to grind off the little wings on the blade Again, due to my very old Craftman jigsaw.#3. It seems to work best at a slower speed. I just gave it enough throttle to keep it moving. That did a much, much better job then the faster strokes.#4. It tosses chips right up in your face. Wear eye protection or keep a strong magnet handy.#5. It's pretty slow. Took about 1 minute per 1" to cut in mild 1/4" plate.For small jobs it's great to have just in case. It does heat the steel alot. By the time I was done it was pretty warm. Gloves not needed, but if I had more than an inch to cut I'd get them.

Wow... I bought these because I had to cut a 15" x 10" piece out of a 36" x 12" x 1/8" aluminum plate, for a 3D printer bed replacement project. I used my Rockwell Bladerunner to do the cutting, which btw these blades work perfectly for. I had cut 1/8" aluminum plate before with the Bladerunner, using the included metal cutting blade. It worked, but it generated a lot of heat and the aluminum had a bad habit of jumping so aggressively that it stung my fingers when it would happen. When this 3D printer project came along, I was very leery of doing my own cutting because of that previous, bad experience. I just hoped that the other reviews for these blades were accurate and that it would be totally a different experience this time around. I am relieved to say, this has been the most pleasant experience I think I've ever had with cutting metal. The aluminum plate never jumped, hardly even vibrated, and the cutting was very smooth, fast and surprisingly low heat. I was able to guide it through the machine with my bare hands, nice and close to the cut, and the metal only became just warm to the touch. I can't speak for how long each blade will last, but they are amazing and they're not at all expensive. I'm very impressed. The only thing I am disappointed about at all is that I hadn't gotten some of these sooner... I could have saved myself a lot of grief with various projects.Rick NR417

Along with cutting fluid, after the first 6 or so inches the cutting slowed down, but kept cutting. Better than some other blades I used that could not finish cutting.

Blades wear out quickley. It took 3 blades to cut about 20" of 1mm 301 Stainless Steel strips

Never used these before but bought them based on reviews for cutting aluminum. They do... however, you have to take it slow. The blade I used didn't suffer any apparent damage cutting 1.5" x 3/4" aluminum rails so I was very happy to see that. I haven't tried them on wood yet, but if they can handle aluminum, wood should be no problem. Plan to use these on a jigsaw table.

Jigsaw blade what can you say except they are expendable so expect to buy more. But these are the best ones I found for cutting aluminum.Recommend these blades this brand.

Fast delivery, great product, exactly as advertised

Cutting 1/2” mild steel plate. 1st attempt blade burnt up / teeth dulled in seconds, so I turned down the speed and added cutting oil. The 2nd blade cut VERY slowly, I got in less than 1/2” and the blade broke. I need to cut a distance of about 4 inches in 1/2” plate. These will never do it. It would take hours and probably 50+ blades.Need to find a plan B, probably sawzall with high quality blades.The price was great and fast delivery so probably ok for very thin material or soft metals like aluminum, copper.

Very good quality

Great blade cuts perfect 👌
