PacTool SS724 Snapper Shear Pro - Cutting Tool for Fiber Cement Board - Power Shears Professional Power Tools

I have come across hundreds of tools in my 28 years as a residential contractor. Some tools serve their purpose better than others. Some tools disappoint you while others go above and beyond their functions making a hard job turn into a pleasant surprise. The Snapper Shear Pro surprised me. I was hesitant at first. But, after attaching it and sticking the first cut I realized that you can’t go wrong with this easy to use tool. Does works as described. Straight cuts every time, fancy shapes cuts. Just amazing, I was able to cut hundreds of fiber cement boards and the tool is still going strong. Easy to attach to most drills…. Look at pictures showing the Snapper Shear Pro attached to a 18v Bosch Cordless Drill.

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.

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.

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.

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.

This product is unbelievable! We used it on our Hardy siding installation and it is so easy to use. Highly recommend this to anyone how likes to be safe and efficient.

The PacTool made quick work of Durock but the edges were quite ragged. I understand that this is actually made for Hardie board and the videos seem to indicate that it does a great job for Hardie board. For Durock cutting I tried multiple options. #1. Jig saw with a wood blade works very well. Cuts fast, minimal dust and a fair edge. .#2. Score and break. This was very labor intensive, made a nice cut with nice edge, couldn't do intricate cuts. #3. circular saw with a masonry blade. Worked well, nice edge, extremely dusty. #4. Angle grinder with a masonry blade. Worked very well, fast, straight cut, great edge, extremely dusty (might want to hold a vacuum next to the grinder as you cut). I liked the angle grinder the best.

I was a bit leery at first, not sure it would work properly on a 18v plus drill. Boy was I wrong. This tool is a must have for Fiber cement siding. It is quiet, smooth, and quick. No Dust, and no flying particles. I was amazed at the tools performance. It cuts curves perfectly, as long as you can keep a straight line, and it makes cutting the boards a breeze. I cannot say enough great things about this tool. This was our first attempt at installing fiber cement siding on our new house, and the tool help take a bit of the stress away. I love it. The dual sided handle makes it great for stability.

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.

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.

Great little unit, works even better than the makita standalone Fc battery cutter. Clean cuts easy to angle up to do tight curves, and the offcut ejecter arm makes sure no curls of cuts impede vision of the cutter gap when working. I use this with my milwaukee m18 drill and it works a treat. The only downside is that you have to use two hands but that's hardly a big deal.highly recommend for anyone that has to cut blueboard villa or Fc sheets quickly and effectively
