The PacTool SS404 Contractor Grade Snapper Shear has been a lifesaver for my home renovation project, especially when tackling large 4x10 sheets of fiber cement siding. Knowing the dangers of silica dust from traditional cutting methods, this tool is a safe and efficient alternative that has made the process smooth and hassle-free.A few tips from my experience:Mind your cut line – The shear removes about 1/4 inch of material during the cut. Keep this in mind to avoid cutting sheets shorter than intended. Align the cut line to the left or right of the guide, not directly in the center.Manage the excess material – The waste curls up as you cut, so periodically clear it to maintain visibility and precision.Watch your cord – The tool's angle tends to catch the power cord on the fresh cut edge, which can cause frustration. Use your free hand to guide the cord away and ensure smooth progress.Overall, this tool is a must-have for professionals and serious DIYers handling fiber cement siding. It’s reliable, effective, and worth every penny.Highly recommend!
