RDEXP Stainless Steel Wire End Brush Pen Shape 1/8 Inch Shank Diameter Pack of 10 - Versatile Cleaning Tool for Precision Work (8mm end brush) Review

I hope you like metal shards because you will get a lot of them. Very cheaply made and will spit a spoked wheel all over your shop, in your eyes and maybe even on your tongue if you grind like Jordan.

They work for a few moments and then come crashing down on you like a Texas Rolling Stone at high speed. They need a tighter fit.

Larger but regular. Eventually I will use them for something and order more in regular sizes. Have only used one so far. But I expect microneedle-sized projectiles will land everywhere, as is usual for bits of this class.
