SS724 Backerboard Snapper Shear Pro

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.

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 after starting a bathroom remodeling project in which I removed old sheetrock and tile and installed concrete backer board. Man oh man I really wish I would have known about this tool before I started cutting my Hardie Backer...I started off using the score and snap method to break my Hardie Backer board, but as one other reviewer said the score and snap method is only for bigger pieces of board; once you start having to measure and cut smaller pieces of concrete board then scoring and snapping just doesn't work unless you possess the strength of three Lou Ferrignos. Further, scoring and snapping leaves sort of a rough, jagged edge that doesn't lend itself well to clean corners. So, after searching for a better way to cut backer board, I bought the SS424. This tool absolutely makes easy work of cutting backer board; I used it to cut half-inch thick board and it worked beautifully. As others have said, it does take practice to learn how to cut along a straight line, but once you get good with it you will never want to use anything else. Some people will say to use a table saw with a special concrete fiber cutting blade, but that way of cutting board creates SO much dust; the SS424 creates almost no dust thus lowering your silica exposure risk. Also, once again as others have said, a little backer board will curl up between the cutting blades and this can get in the way of following your cutting line, but after a few cuts you sort of learn to deal with it. If you have tried scoring and snapping do yourself a favor and buy this tool. I'm pretty sure that if they made backer board back in the 14th century then Dante would have listed scoring and snapping this stuff all day as the tenth circle of Hell. I like this tool so much that I considered buying a second one just so I can sleep next to it at night. Thanks, I hope this review helped someone.

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.

Had been wondering if there was A tool that cut Hardie board without the crazy dust when using circular saw. Well this is It. What an absolute awesome tool. It cuts/shears concrete board literally like butter. With an minimal mess. So glad I purchased. It works like a dream.

If you are doing a hardie siding project this is totally worth getting. It doesn’t make any dust and it easy to use.

I really did not look forward to cutting several fibercement boards. Then I saw this contraption being promoted as the way to cut cement boards. I decided to buy it and giving it a shot. I only cut 1/4 inch boards. Do not know whether thicker boards do work the same. But man, am I happy I got this! Hooked this up to my 18 V drill, and a minute later I had a 4x8 board to size!!!! The first 6 inches look a bit rough. Then I put the drill on high speed and the cut was perfect. The amount of dust was minimal. It makes strings of maybe 1/8th of an inch, but dust, barely. Cement board cutting anxiety --> GONE.

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.
