That device looks like it's made from about $2 of common hardware store items. I ruined a couple of similarly priced grommet tools from another supplier before I decided to use the installation method of a ball peen hammer tapped by a regular hammer. All you need is the badge and the grommet if you already have a ball peen hammer and a regular hammer. If you need a ball peen hammer, I recommend the small ones that are usually found in the $2 bargain bins at the hardware store.
I posted this in here in June of 2010:
You can easily and efficiently install a badge with a new grommet with no need for special tools. Replacement grommets are readily available on eBay or from any one of several drum shops and drum parts vendors. They are inexpensive. Just determine which finish you want (brass, nickel, chrome, black, etc.) I have invested in the usual overpriced nut-bolt-washer special grommet tool with mixed results in grommet installation. I found that the simplest and most effective method was to use a ball peen hammer and a regular hammer.
1. insert the open end of the grommet through the badge and the outer side of the shell
2. place area of shell with the badge face down on a solid surface like a work bench
3. place the ball end of the ball peen hammer on the open end of grommet
4. tap gently a few times on the flat side of the ball peen hammer with the regular hammer
The open end of the grommet will roll up to form a collar that matches the rolled collar on the finished out side of the badge. Just be sure to use a grommet of sufficient length to do the job without being too long. And, be very gentle with the hammer blows to the extremely soft and malleable metal of the grommet. Hammer it in place just snugly enough to not spin, but not too snug so as to distort the badge.
