Haven’t really had the time to really use it but each time I did, it worked great. Can’t beat it for the price.

Nice product

This Gunpla Micro Pneumatic Pencil Die Grinder works well and handles very nicely. I didn't know what to expect since this was my first pneumatic tool but I am impressed with the power to weight ratio and how well it spins up to do its job.The one, and major item, I didn't like about it is that this tool uses a lot of air. I had it hooked up to my small home air compressor and the compressor had to run full time to keep up. Although the webpage for this tool does specify the air pressure needed to run this tool, it should probably also state the compressor size needed to run it. My compressor can achieve 90 psi easily but my tank is a smaller tank used for airbrush tools and even after letting my tank get to 150psi, it would exhaust the supply after less than a minute or so. I can use this tool for smaller tasks like deburring or a little grinding but anything more extensive and I will not have the air supply needed to keep it going unless I want to listen to the compressor going on all the time.The tool is small and fits in my hand comfortably. It is easy to control and accepts all the normal Dremel bits so it can work interchangeably with my electric rotary tool but until I can get a larger air supply, it will be easier to just use the electric rotary since the whine of the electric motor is not as intrusive as the full racket of the compressor going on full-time.

works well

This one has actually brought me to really appreciate having a pencil grinder! It is a rather lightweight body, and I definitely wouldn’t say it’s built up for heavy professional use, but it’s been one very useful for lots of my projects! I can use regular dremel bits and from cleaning up the small welds I do on a framed signs I make, to working with epoxy/wood projects, and even roughing up a surface for a patch, it’s worked out great for me! - (Not to mention I can forget about battery life or forgetting to charge like I used to LOL!) - Nice and agile and has a pretty flexible whip hose - Use your regulator to control - Definitely pleased with this one! 9.7/10 a win for me!
