That looks like a plumbing tool. Is that a steerer tube specific tool?

 

This is what I use: Flap Wheel, Shank Mounted, 1" x 1"

Mine has a longer shank (6") tho, held on by 2 set screws.

 

File it away.

 

Pipe deburring tool. Several tool companies manufacture them, but they're all the same: carbon steel blades sharpened/placed in a cone configuration.

I'm poor and just use a half round file to smooth out cut steerers.

 

If I were the steerer tube deburr guy on the assembly line, I might entertain something like this. But I can cleanup and deburr a steerer tube in just a few minutes with a file. I always enjoy expanding my tool collection, but normally when that new tool serves a specialty purpose or makes the task significantly easier or faster. For me personally, this isn't one of those tools.

 

If you do get one OP I'd be sure to get one that does both inner/outer diameters. I'd also try to find one rated for aluminum as some of the cheaper one's blades will just dig in and makes nicks. I use this for work projects and like it.

Used them in the shop and they were pretty handy when cutting down aluminum bars and steerers, shortening seat posts on kids bikes etc...things done pretty often. On our own bikes I do that stuff so rarely that files work fine. As mentioned by others, they're commonly available at pluming/hardware/tool/Amazon. In many the barrel is plastic and I'd look for a metal one.

 

Whalenard's link is a nice looking metal one.

 

I've always used a bit of sandpaper. because I always seem to have a bit on hand.

 

Initially I was morally opposed to this tool, especially the $36 metal ones. But the plastic $9 ones I could see myself giving them a go. My current method is a cordless dremel with a stone tip.
