This extension-equipped die grinder is a vital tool for internal polishing and finishing. It enables me to reach hard-to-reach places with conventional tools and finish them smoothly and evenly. It's easy to polish inside thanks to the longer reach. This is an essential tool.

I was worried that the die grinder's performance could be impacted by the expanded reach, but it hasn't. It continues to operate smoothly and provide steady electricity. The Shinano brand's quality is readily obvious. It functions perfectly.

In the past, it was quite difficult to work deep inside assemblies. I'm much less tired now that I don't have to bend myself into uncomfortable positions thanks to the SI-2022S's increased reach. There is very little vibration and the tool is properly balanced. My workflow has improved because to this tool.

I do a lot of complex metalwork in tight, cramped locations, and this die grinder with the extension is great. It helps me to reach regions that would otherwise be unreachable. Fine detail work is made possible by the small diameter. For me, this technology has created a lot of new opportunities.

When it comes to porting cylinder heads, the SI-2022S's extended collet is invaluable. I was unable to precisely reach deep into the ports with my standard die grinder. The control is still outstanding, even with the extension. It has greatly simplified the porting process.

I've been using this grinder for grinding, shaping, and finishing work, and it has exceeded my expectations. The extended reach is a game-changer, allowing me to work on deep welds and tight corners effortlessly. Very little vibration, excellent control, and top-notch Shinano durability.
