Default small flush trim bit

I'm looking for the smallest pin guided flush trim bit i can find.

I want to use a template to make multiple copies, but i need a very thin flush trim. I cant see a bearing being small enough, anyone?

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

Nope.
Imagine a bearing guided flush trim bit. Now imagine that bit only 3/16" diameter. I need a guiding surface to follow the template.
I have pin guided round over bits, but I cant find a straight flush trim with a pin guide.

Rotozip straight bits have no cutting edge on the first quarter inch which is used to guide the bit around the outside of say electrical boxes,but think the smallest is 1/8”

Ahh, thats clearer thanks. The first link just looked like abrasive drill bits to me.

Now I just have to find a supplier a few thousand miles nearer.

looks like these are 1/8" shafts. I want it for my router table. 6 mm is the smallest collet I have.
Still looking.

They sell adapters to use Roto Zip bits in 1/4" router collets here, so they may also offer them elsewhere. I use them with the adapter in my smaller routers.

Without a bearing on the tip they require a lubricant or you will burn the edge of your template. This is also helpful if using a router bit with a brass guide tip. I brush a thin layer of Vaseline on the template edge where the guide tip will rub. I also do this when using the solid carbide laminate trimmer bits to trim laminate, basically any bit that has a smooth guide but no bearing, or a bearing that isn't spinning all that free. It can make a mess if you use too much, but it does eliminate the the burning.

On the few occasions I want to go less than my 1/4" flush trim bit, I use a scroll or sabre saw, works well for me, even if doing multiples. I call templates masters.
