What is Reddit's opinion of Acrux7 Metal Deburring Tool Kit, 15pcs Rotary Deburr Blades Set with Handle Debur Knife, Great Burr Remover Hand Tool Aluminum Deburring Tool for Plastic, Wood, Copper and Steel (Blue)?

From 3.5 billion Reddit comments

This is the deburrer I bought a few years back. It was recommended as it comes with a few different cutting edges, but you .

It works well. The heads on these swivel, so they shave instead of gouge.

It's a replacement tool for a router and countersink drill bit. Knocks off hard edges and can easily make room for a screw head.

Edit: Here, see it in action.

I use this one but there are even cheaper models if you don't care about getting the extra bits.

You could try a deburring tool. Or if you're feeling really bold, try flaming the edge with a torch. Or just some good old fashioned fine sandpaper.
