Description
Remember when you had the perfect tool for siding right by your side? Glide through fiber cement up to 0.5 inches (13mm) thick with the OSHA-compliant WEN Corded Fiber Cement Shears. Take on siding, fiber cement, Hardie board, and shower backer board at a rate of up to 18 feet per minute. The lightweight 4.7-pound design combines with the lock-on power switch to limit fatigue during operation. The included reversible steel blades handle up to 20,000 linear feet of cutting per set before needing to be replaced. The pressure- sensitive trigger adjusts the speed of the cut anywhere from 0 to 2500 strokes per minute, depending on the force applied. The pivoting head rotates a full 360 degrees, allowing you to cut at any angle or direction without having to have an awkward or uncomfortable hold on the shear's handle. And, because it’s a WEN product, your fiber cement shear comes backed by a two-year warranty, a stocked inventory of replacement parts, and a friendly customer phone line, all to make sure you remember WEN.

Did the job, great for smaller projects, Very very low Dusting
Style: Corded Fiber Cement Shear
Basically they did what they were supposed to do. they cut around 12 boards for me 1/4in thick Hardie fiber cement siding, very very little dust. made the cuts fairly clean. Best thing is there was no dust. I would recommend for smaller projects for siding, patch work or small installs. If you have to do an entire home...then no. But fact is the dust from fiber cement siding is NO GOOD for you. These keep the dust to a point that if you cut outside you wont need a mask..but I would wear 1 anyways. The only thing I would say is as you cut the siding that its snipping off tends to roll up and it blocks the line you drew to cut on becuz there is nothing to make it curl off the the side like a small guide you may see on more expensive fiber board sheers. this is a little annoying but can be worked around, for the price Its great. I plan of just making a small part to guide the shavings out of my way and attach to the sheers. But they did the work and were very cost effective

Worth it! Here are a couple of tips…
Style: Corded Fiber Cement Shear
I rarely leave reviews. But I wanted to offer some advice. Draw your lines on the backside of the siding and cut it upside down as it leaves the clean edge on the underside. I don’t know why it took me so long to realize (4th side of the chicken coop haha). It cuts best if you tilt a little forward. Overall well worth it especially if you’re not doing siding for a living.

Difficult to use and inaccurate
Style: Corded Fiber Cement Shear
Unfortunately, I did not try this product out until after my return window expired. It is very difficult to maintain the line. It is choppy and there were no acceptable cuts that stay within the guidelines of the installation requirements of my cement board siding. I may try to contact the maker of this product to see if there is any way to return to this. I am having good luck with my chop saw, skillsaw and jigsaw with the correct blades. This review is not a reflection of the seller but the product. I would have given it zero stars if I could have. Thank you.

Worked like a charm.
Style: Corded Fiber Cement Shear
Had never used cement board siding on any project. Purchased this WEN Shear because I had a couple hundred linear feet of cuts to make and had heard saw blades wear quickly and produce a lot of dust. This shear worked flawlessly, cutting through the board faster than I thought it would. The cut edge it produced was clean and the process was virtually dust-free. Also, it is a lot quieter than a saw. All of these type to shears produce thin coils of waste (chips) as you cut which requires you to constantly brush out of the way as you go, but clean up is as simple as sweeping them off the floor when you're done. Overall, very satisfied with this tool. I am not highly skilled at this type of work, but found it to work great and it was simple to use. Highly recommended.

Simple and cheap way to cut fiber cement lap siding
Style: Corded Fiber Cement Shear
This makes cutting James Hardie siding extremely easy. I have used it to rip a starter piece, cut a notch, and of course for cutting my planks to size. It is relatively easy to use and so far the cuts have been straight. Time will tell how long the blade lasts but so far it is working great. I especially like it is not as messy and noisy as using a saw blade. For the price, it is great and recommend. It was cheaper than buying a 10" blade for my mitre saw but I did still need a blade for my table saw to do the Hardie trim which is too thick for the shear tool.

too slow
Style: Corded Fiber Cement Shear
Robust tool. Returned because its just too slow to be productive and takes quite a bit of force to push thru material. Put a room fan behind me to direct dust and used a circular saw with fiber cement blade. Also found my jigsaw with carbide blade worked well.

amazing value amazing value
Style: Corded Fiber Cement Shear
Fiber cement needs special tools because it is so tough. An appropriate circular saw blade is expensive and makes a lot of dangerous dust (it cannot be used indoors). This is an outstanding alternative -- it is simple to use and permits very accurate cuts including angle cuts for meeting roof-lines etc. This plus a jig saw blade for cut-outs etc are all you need. I've never used the much more expensive versions (but) I cannot image what could make them worth the money. This is a deal.

Worth it
Style: Corded Fiber Cement Shear
Well worth it. No dust made it worthwhile. Used it to cut 5/16 hardie siding from Lowe’s. Had to use a circular saw to cut the hardier trim and the dust was annoying and required masking
