This sander works incredibly well for feathering edges or blending paint. The steady airflow helps avoid overheating, and the balance and control enable extremely accurate work. It's essential to my restoration projects in order to get outcomes that look professional.

I value the SI-2210's accurate speed control. It enables me to modify the RPMs for various materials, such as composites, wood, and metal. This adaptability is crucial to my many endeavors. The control responds quickly.

My everyday driver in the shop is now this Shinano sander. It is robustly constructed and has withstood continuous use. The entire build quality is superb, and the air motor is robust and reliable. I have no doubt that it will endure for many years.

The 4-inch size of this sander is great for getting into tight spots and working on curved surfaces. I use this sander to reach places that larger sanders just cannot since I do a lot of custom manufacturing. For its small, the power is still more than sufficient.

Among the air disc sanders I've tested, the SI-2210 is notable for its seamless functioning. Because of the exceptionally low vibration, significantly finer control and a better finish are possible. For my car paint prep job, this is essential. It leaves behind an extremely stable surface.
