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

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.

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.

The media could not be loaded. We bought this tool last month and started using it for the first time yesterday and so far all I can say is it’s an amazing piece of tool! Was a bit skeptical at first since the big stores don’t carry it and there are not a lot of videos of it around, but we took a chance and it paid off!

The shears worked very well for cutting HardiPlank cement board siding. I used it to crosscut for lengths, as well as ripping lengthwise for width of starter and top course. It is much faster than a jig saw with diamond grit blade. The jigsaw cut super smooth edge but was very slow. These shears cut a slightly rough edge but totally acceptable for the hidden areas. Remember to paint with primer all cut edges.The shears cut about a 1/4” wide strip. Each edge of the cut is 1.5” from the edge of the corresponding sole plate edge guide. I clamped a 7” rafting Square 1.5” shy of the cut line and ran the edge of the shear’s sole plate/shoe along that. It is a bit awkward to try to cut freehand but could be done for all except butted ends For butting to another plank I would try to have both be factory ends, and have the cut on the end by the trim.For cutting lengthwise I placed another plank alongside it, and then stacked four planks on a guideline 1.5” from the cut line. The factory edges have tiny rough spots so be careful as the guide shoe will hang up a bit. Just be patient and smoothly push the shear head along the guide planks. Next time I will use a 2x4 or similar smooth wood cutting guide rather than another plank.It is much easier to handle the planks and set up cutting guides with two people but could be done by a lone worker.I used an older Milwaukee M18 1/2” drill/driver and it had no problem driving the shears. Use the highest drill speed possible. The shears produce virtually no air borne dust. You get some dust on the floor with 1/4” wide curled strips as waste products. Clean up periodically before the curly strips get stepped on and create much more cement dust. The jigsaw created more dust but it was very localized near the saw, unlike how a circular saw throws dust across the entire room. Jigsaw cuts ultra smooth but is very slow, like two minutes to trim length on a 6.26” plank. The shears take about 15 seconds.Bottom line, the shears are the only reasonable way time-wise and with minimal dust to cut HardiPlank. You get acceptable edges in fairly good time and almost no dust in the air. The main downside is they are awkward to control and you should use a firm guide to ensure straight cuts.This shear head is way cheaper than the full tool shears. Plus you get the benefit of working with any corded or cordless drill of 18/20 volts. Be sure to really crank the chuck closed on the head stem as it likes to work itself free. I will always have a jigsaw handy as a backup but these shears are what I will be using for all the siding I am doing in the coming months. Totally worth it!By the way, HardiPlank looks very nice on the house. When we cut ends or edges we just generously coated them with primer and put them up immediately, no waiting for it to fully dry. We even went ahead and primed over every nail head, just in case (I used the pre-primed planks which I think is the easiest version to work with).

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.

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.

The item is good but it you planing to use it with battery power drill Don’t I mess up two of my drills it seem like it need a lot of power so my drills cost more than this accessories but well is what it is
