With more and more power tools, whether traditionally air powered or plug-in, becoming available in cordless versions, people often wonder whether the cordless version have as much power and performance as their tradition counterparts. Die grinders are certainly one of those tools that I have wondered about, and the Torque Test Channel is here to do the test and let us know if the cordless variety can actually hang.

In order to test these things, power had to be tested with a dyno and so a die grinder dyno was built!

Video Description:

As always Torque who started this channel is working for Astro Tools who’s 201 and 204 air die grinders were also included in this testing, though assuming a die grinder is healthy, most 1/3HP die grinders should make around this same power. It’s all about durability, gear smoothness and ergonomics after that. So while these air models make more power compared to M12 CORDLESS, they in themselves aren’t unusual in that regard.
