BOSCHT141HM1 1-Piece 4 In. 6 TPI Carbide-Tipped Special for Fiber and Plaster T-Shank Jig Saw Blades

I am building a pretty big outdoor BBQ island using steel studs and Hardie Backerboard 1/2" thick cement boards. There are a lot of details in my design and requires a good amount of detailed cutting of the cement boards -- including 3 electrical outlets, 1 light switch, 4 ventilation rectangular holes, a cutout for the sink, a cutout for the side burner, 3 storage doors, and a series of angled cuts for the bar area. Translation: I needed to cut a total of at least 100' of 1/2" cement board with a controlled saw -- namely, a jigsaw.At first, I tried a number of different jigsaw blades that I already had -- which turns out to be all blades designed for cutting woods and metals. Those blades would last about 1' through the cement board before their teeth was completely grinded down to a smooth surface. I did manage to get as much as 2' with a couple of them. After eating through 5-6 blades with less than 10' of cement board cut, I found this Bosch T141HM1 on Amazon. It fit perfectly in my Black & Decker JS660 Jig Saw with Smart Select Dial.I am very pleased to say, that this single blade alone was able to take me through the rest of all the cuts needed for my BBQ island and I see no visible wear on the teeth after all those cuts! Also, it's a very sturdy blade -- without bending or twisting when making round cuts. If you're looking to cut fine details or cutouts in cement boards like Hardie, Wonderboard, Durarock, etc., I would HIGHLY recommend you stop search and buy this blade! You won't regret it!Word of caution: Do make sure you wear protective gear when cutting cement boards as it will produce a lot of silica dust -- known to cause cancer.

After using several other brands and different blades for various materials, metal, wood, wood with nails, etc, these by far outperformed Diablo, Milwaukee, and a few others. Faster than multi-tool, better than table saw when having to rip just a few or cutting around walls, toilets, any other obstacles that you’re bound to encounter when laying lots of flooring. Can’t speak to how they work for any other materials, only bought these to try on LVP, all other blades I’ve tried were good for one full rip before they slowed down until it was faster to just get out a multi-tool or score and break like the ends, only it’s quite a bit harder to score and break one long ways, and that sure won’t work when cutting around other obstacles.. if you’re just doing something as simple as a single bathroom buy these, it’ll be worth it. If you’re doing lots of flooring, definitely buy these, save yourself some time!! They work, I’ve got probably 8 rips and half dozen corners cut on one blade so far and it has barely dulled or slowed. They do have a pretty large kerf and I have busted a couple teeth making too sharp a curve cut. Still cuts fast and clean though. Just don’t expect to make any tight turns.

If you are cutting LVP you need this blade. Other blades will dull with 2-3 cuts. This did the whole job (Whole house).

wanted a smooth cutting blade for most materials, this one fits the bill very well

I do a lot of stainless work and they last longer than any other blade I have tried, but even with cutting fluid they should stand up longer on 1/8" or more stainless.

I purchased these primarily to make precision cuts in thick laminate shelves and the results were outstanding. The cut edges were extremely smooth and free from any chipping on either side of the shelves. I highly recommend.

I used this blade to cut 7mm laminate floor. I cut roughly 25 linear feet of laminate with this blade in a job totaling 330 sq ft. It didn't lose it's sharpness or effectiveness. It had good control for angular cuts and it didn't split the laminate. Note that this was very low quality laminate, I would expect this to work even better for higher quality laminates.This can also serve double duty for wood, vinyl, plastic, etc so it'll stay in my shop for future use.I noticed a neat feature, the bottom half of the teeth are aimed up and the top half are aimed down. The middle teeth are generally straight and low profile. A very clever feature.While expensive, it was worth it to me to use this blade and it saved me time on the job.
