I do a lot of bathroom and kitchen remodels, and many times, that calls for tile work. Several years ago, I needed something better than a saw to cut 1/2" Hardibacker board, because of all the cement dust they kick up. I bought one of these directly from Pacific Tool when the local lumber/hardware supplier only carried the S404 Snapper Shear. Loved it from the first time I used it, and it went through a lot of remodels before the motor burned out a couple of months ago. I called Pacific Tool directly, and they confirmed my suspicions about the motor,and they were able to 2nd day a new one to me.This tool cuts backer board like a hot knife through butter, going through five feet of 1/2" Hardiboard in less than a 30 seconds.It does accurate inside corners, and with a little practice and finesse, you can do trim cuts quickly, and neatly,such as when the cut board is just a bit on the tight side.

We purchased this item for our business as we are a retail tile store and installation business. The installers that use it are amazed at how fast and dustless the cuts are. We purchased the SS424 because it cuts both 1/2" and 1/4" backer board. Our production has gone up because it saves installers time, They can cut right inside the job area instead of going outside to the saw to make cuts. Our customers love it because there is very little if any dust at all at the job site. This item does not cut siding. If you want a siding cutter, search for "Siding Cutter" a Backerboard shear will NOT cut siding.

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 made a video review of this product on youtube and I am impressed with the performance. As a pro remodeler doing a lot of baths I'm using this tool to cut Hardibacker cement board. With correct technique, the tool works flawlessly. I still use a jigsaw for tight circles, but the shear works great for straight or slightly curved lines. It's quiet and creates minimal dust. The drill portion of the shear is nothing special, but it has enough power and seems sturdy enough to last. The power cord strain relief can sometimes lodge itself in the cut as you go, but it's not the end of the world. I do wish they provided more than just a cardboard box to hold the tool. Even a cheap bag would be welcome, especially considering the price of the tool. If you're a pro, it's worth owning. If you're a homeowner with a single project you might be better sticking with a jigsaw and coarse wood blades or else renting this tool.

If you've ever cut HardiBacker with any other method, you will appreciate the speed and accuracy that this tool provides--not to mention the virtually dust-free operation. This shear allows you to make cuts as fast as a circular saw in 1/4" and 1/2" backer board but without the mess. You can also use it to trim even 1/8" of material off a piece that is too large, making it ideal for custom fitting irregular shapes.

The only criticism I can levy is that I wish the cutting head was 90 degrees to the board--as it is on their cordless model. As it is, the power cord has a tendency to get caught in the kerf of the cut. The flatter you hold the tool to the blades, the cleaner the cut; unfortunately, doing this tends to press the power cord against the board and drag the cord into the kerf. Small nit, but fixing this would make an otherwise excellent tool perfect.

I have been installing ceramic tile for 10 years. The worst part of the job is cutting the backerboard. The special saw blades work great but produce so much dust that you have to use them outside. I live in NW Pennsylvania. Cutting outside isn't an option in the winter. Using a knife to score the board, then snapping it off never seems to work well. I finally broke down and bought this backerboard shear. I'm kicking myself for spending the last 10 years inhaling backerboard dust. (which by the way contains silica and is rather harmful to your lungs.)

This shear cut 1/2" hardibacker like scissors cut paper. It was easy to cut straight lines and subtle curves. Tight curves took some creativity. (like the hole for a toilet) I cut the backerboard for my most current job in the kitchen of the house I was working on. A few minutes with a broom at the end of the day was all the cleanup I had.

I can't speak to its durability because I have only owned it for two months. The shear, however, seems to be well made and is quite hefty. Before I bought it I called the customer service number at PacTool. I spoke with a very nice lady about the warranty. She informed me that once they receive the item they have a two day turn around on all repairs. That in itself was enough to convince me to give it a try.
