Triton TRA-001 Router table trouble!

[Dissolve]

Hello,

I currently have a Triton TRA-001 mounted to an INCRA router table plate which is mounted (temporarily) into a 36mm thick MDF bench top until I build a purpose built cabinet/table.

I purchased a 4 Fluted multi-trim bit from Wealden Tools which looks like it should be perfect for my needs:

I locked it into my Triton, checked it was secure, set the bit height for some test cuts, switched on the router at full speed (20,000 rpm) and the bit started but it made quite bit of vibration to begin with so I took it out, inspected it, everything seems fine with the bit so I tried it with a lower speed and the vibration went away.

Problem is when I did a few test p[***** I was getting a slightly "chattered" finish. I will upload a photo to illustrate this, but I'm not sure whats causing it, either the bit itself, the accuracy of the router itself or maybe the router table/plate setup?

What sort of max speed would be suitable for this bit?

Wealden will advise on the appropriate speed for this bit. They are very helpful and a phone call will provide the answer. One thing occurs to me is that the cutting edges may not be precisely the same distance from the centre of the bit. In any case I'm sure that Wealden will have the answer.
I assume you are an experienced router user and are not working the timber in the wrong direction on the table.

It's a fairly hefty bit for top speed. I have a similar bit that I use for template routing, same diameter, I think. I wouldn't run that on 20K. I think you'll be fine using it as you are now.

Hi guys,

Yes I am fairly experienced with simple hand router use but I have recently started delving in a bit deeper but I am familiar with all the basic do's and don'ts

This is the largest bit I've used yet, what sort of speed would you recommend for a bit like this? I have read that the fact it's 4 fluted instead of two doesn't actually make any difference to the running speed due to waste removal, so it should be treated like a normal 2 fluted bit?

Also how will the speed of the bit effect the cut in terms of finish/tearout etc?

I have contacted wealden regarding the speed usage etc and the strange choppy effect I am getting.
