PacTool Snapper Shear Pro - Fiber Cement Cutting Tool for Siding Pros

I bought this tool to cut Hardie Plank because I didn't want to deal with the nasty, dangerous dust you get with a saw, and I'm glad I did. A saw might give a perfectly clean cut, but the need to use a vacuum, SERIOUS dust mask, and tight goggles would have negated that advantage. (note: Some will say that you don't need to go all space-suit when using a saw, but you'll be sorry if you don't) This shear/nibbler takes a little practice, but after a couple of cuts, you're getting very nice results. It's not difficult to produce cuts to within 1/8th inch, and often to within 1/16th inch accuracy. You can also do respectable curve cuts if needed, and the amount of dust produced is minimal. The slightly furry edge of the cuts can be smoothed, if needed, with a small sure-form rasp. Remember to prime all cuts before installation - Cement Fiber absorbs water, and caulking, where used, will adhere much better to primed material. The Pac Tool shear won't be as durable as a $400-$500 dedicated nibbler, but it's held up very well during my one-off siding project, still cutting like new after about 100 planks, including several long rip cuts. If you're only doing one small-to-medium sized siding project, rather than an entire LARGE house, this tool should do the job to your satisfaction. I'm glad I bought it.

Wow! This is one of the best gadgets I have ever bought. Just amazing how easily it cuts cement board. And no dust! I wish I could give it 6 stars.

This is the first time I have ever needed to cut Hardi Backer (1/4 inch thick cement board) and this tool worked fantastic. Looking online, there are a number of different ways to cut cement board, but the other methods seemed prone to cracking or having rough edges. Since I have never used any method other than this pactool to cut cement board, I cannot verify this is true, however, I can say the pactool provided very smooth edges without cracking. I it was also easy to cut corners and round the edges. Super easy to use right out of the box. Just envision cutting cement board using a pair of scissors and you get the concept of how this tool works.

I'm doing a job where I have to cut a lot of fiber cement backer boards. I came across this tool and after watching many videos on YouTube showing how clean and easy the PacTool SS724 Snapper Shear Pro cuts through up to 1/2" thick Hardie board and other fiber cement boards. There were no videos showing it being used specifically on Durock fiber cement backer board. But since it said it works on fiber cement board I decided to purchase it. The tool is well built and feels of good quality in your hand. All the YouTube videos I watched showed the tool easily and cleanly cutting through Hardie and other cement boards ( but not Durock ) leaving just a clean strip of cement board ribbon behind. This is not true for Durock fiber cement board. I used the tool to cut through 1/2" Durock fiber cement board. The tool does easily go through the Durock but it is not cutting the Durock fiber cement board. It is crushing the cement board leaving a lot of crumbled pieces of cement board and debris all over the floor and the work piece. Knowing that I was cutting through fiber cement board I wasn't expecting a nice smooth clean cut to begin with. But I wasn't expecting it to be as bad as it was. The cut or more like crushed edge of the durock was jagged and had broken pieces and fiber mesh hanging off it. I had to removed the broken pieces and clean up the fiber mesh strands with a scissors. I can't see cutting anything but a straight line on Durock. Trying to cut a circle, curved or radius cuts will result in breaking chunks of it off. There was no nice clean 1/2" strip of ribbon coming off the tool like all the video showed. That being said the cut edge of the Durock will be good for the majority of the jobs where the backer board seams will be taped over with fiber mesh tape and a water proofing coating or thin set for tiles will be applied. I am satisfied with the quality of the tool and the tool did do what it was supposed to do but just a not as good a job on the Durock as I was expecting. The most important thing to mention is that it makes almost no dust when compared to using a circular saw or grinder. It does leave a lot of debris on the work surface and the floor. You should still wear a mask but no cement dust will be flying around the room getting on everything.

The tool helped me a lot. I removed the bathroom floor tiles with ease.

It cuts, if cut is the right word...more like demolishes a line. But, the main problem is it keeps coming lose in the chuck. I tried it on three different battery powered drills and every one of them came loose over and over again. I even tried tightening the chuck with water pump pliers but it still came loose several times. I imagine this tool is destroying my drill with all the torque required and the slamming/hammering nature of the cutter mechanism.

I wish I knew about this tool thirty years ago! It cuts through cement board like butter and produces almost no dust at all! Hooked it up to my half inch DeWalt electric drill and and cut a clean line with almost no resistance on 1/2 inch cement board. Highly recommend this for DIY or professionals.

Solid product that makes quick (and tidy) work of Hardibacker. I was only doing 1/4" flooring, but it's much easier and faster than scoring/snapping. Minimal dust, but it does remove about a quarter-inch of material so be sure to attend to your line. I would throw the curly bits away/vacuum between cuts just to keep the debris to a minimum. It chucks up easily to the drill motor. (I used Dewalt Cordless). I also discovered that you need to keep the base pressed against the material or it chews up the edges. For those with a lesser rating/poor experience with this product, maybe that was the issue? At about 1/3 the price of a a dedicated drill/cutter combo, this is a solid win and I'm glad it's in my tool kit.

Es muy práctica x la limpieza, elimina el polvo, con cualquier taladro funciona

I have used this all summer to install Hardie lap siding on my house and it has worked like a champ! Once you get used to it, you don’t need to use the handle but can steer the tool easily with the one hand holding the drill freeing up your other hand to hold the material or lift it off a saw horse to go over. It’s so nice to have minimal silica dust in the air! Does leave a rough edge and hard to cut a perfect 90 so not for butt joints unless you use a masonry blade on an angle grinder (highly recommend) to smooth the edge first. I was able to borrow a guillotine style shear from a friend for the straight 90 cuts all the way across the board which also creates very little dust.

Works like a charm cutting the fibreboard. Its scissors action can be controlled without accessive vibration. Managed to cut a fairly clean straight line for a ceiling manhole. Would highly recommend it

0 stars. Bought 2 as have 50 sheets of 12mm cement board to cut and both have sheared and broke after 1 hour. Don't waste your money.
