Looking for a "Roller" to Knurl some ML Bullets?

[KnightExtreme]

Was looking for a way (easy) to Knurl ML Bullets and found someone using this Roller (see attached)
Wondering where 1 might find something like this, it looked easy to use and maybe getting more consitency?
Anyone know where to find such a roller?
Thanks

Looks like a knurling tool intended for use with a lathe. You should be able to find one at a machinery supply like Grainger, McMaster/Carr or MSC.

Maybe something like this that has the cutting edges not just a Roller tool?

Being this all new for me just looking at something as 2 Files is okay but being a "novice" Simple is best for me?

There’s a dude on Facebook that makes a Knurling tool. It gets mixed reviews.

Two files works just fine.

Knurling Bullets

Wanted to bring this back to the top. Is there a post or does anyone have a video link of how to Knurl a bullet and what tools I would need.

Here is the Video of the Roller I was looking for it is not simple sniping a simple picture from it.

From what the member referred a link is what I was hoping to get a more "consistent" results. Using 2 files is mention on a few forums but thought a Roller like what is use in this uTube Video would be a better way and trying to get the bullet in the right position each time but by just having between the 2 Rollers and rolling over a File should make Easy for a newbie. I get some have done this for years and have the right skills but for someone like myself and not sure how well it will turn was why I was asking.
Then I came across the amaozn lnk (above) but hard to know if those like some on amazon will even work?
Also Not a Facebook User so can't see what is on Facebook.

But these are more for usage with a Lathe and stuff like that like a machinist would use?
Guess there is a lot more to knurling ML Bullets.
Was hoping to find a way that is easy & consistent - guess that is never what happens with muzzleloading stuff?
Guess I will just allow my bullets be loose and hope for some good shooting results. Takes a lot just to do Muzzleloading the best right way... (for me anyway)
