Our Testing Experience
First Impressions
When I first took the BOSCH GSA18V-126N PROFACTOR out of the box, I was impressed by its solid build and comfortable grip. It felt light and well-balanced in my hands, measuring just 6.3 x 3.5 x 18.5 inches, which made it easy to hold and maneuver. I started testing it on some scrap wood and metal pieces to see how powerful it really was. Right away, the 1-1/4″ stroke and high speed of up to 3,000 SPM made cutting through tough materials feel smooth and fast. It was clear this tool was made for serious work.
Daily Use
Over the next few days, I used the saw on different projects around the house, from cutting old pipes to trimming wood for a new shelf. The tool-free blade change was a real time saver, especially when switching between metal and wood blades. I also appreciated how easy it was to adjust the six-speed settings depending on the material and task at hand. The saw felt responsive and powerful without being noisy or hard to control.
Key Features in Action
The BITURBO brushless technology really stood out during use. It gave the saw extra power and kept the battery life longer than I expected, especially when paired with the CORE18V battery. Another feature I loved was the KickBack Control—it made me feel safer because the saw automatically stopped if it sensed any sudden resistance, preventing accidents. The adaptive speed control and end-of-cut detection also worked smoothly, helping me make precise cuts without constantly stopping to adjust settings.
Long-Term Performance
After using the saw for several weeks, I found that it kept performing like new. The brushless motor stayed strong, and I didn’t notice any drop in power or speed. The controls remained easy to use, and the tool-free blade change still worked perfectly. Overall, the BOSCH GSA18V-126N PROFACTOR proved to be a reliable and efficient tool that I would trust for both DIY projects and professional jobs.
