round over cutter for trim router

marcros · 8 Mar 2019

I need to buy a rounder bit for my katsu router. It is to break the sharp edges of furniture, but to try and maintain a square looking corner.

Is the Weldon r1.5mm the one to go for? https://www.wealdentool.com/acatalog/On ... g_964.html

I’ve found the 1.5mm to be a little small for what I do and got a 2mm instead which was perfect.

Although I imagine the 1.5mm would be fine for small projects and furniture rather than the production joinery.

These cutters are always deceptive - the curve always looks much bigger on the cutter than on the finished cut. I just worked it out out of curiosity - the actual arris removed with the 2mm cutter is only about 0.85mm.

so the difference between the 1.5 and 2 is going to be virtually nothing? makes me wonder why they sell both options.

around 0.85mm - 0.62mm About a 1/5th of mil difference.

I bought #T1301B a few weeks ago (around Christmas time), but haven't yet used it.

I agree it looks like a too-small radius in my hand, but I'm slightly more worried about the top of the cutter digging-in if I rock it accidentally. It's going to need practice, as my Bosch routers are taller than the Makita/Katsu type (I think), and thus probably more wobbly.

As everything Wealden though it's well finished, very sharp and nicely made overall. It's also just over 90 degrees, so my fears of leaving marks might be unjustified.
