Poor cut quality

[magicniner]

It's worth reading up on engraving tool geometry as wrong-uns look good if you don't know where to look, this is a fair description -

Hi Thanks for the information, unfortunately i couldn't get any sensible numbers out of pilotltd I dont think its quite the right tool for the job.

Im going to try the Mega Electronics tool £10 each and if not there is a Bantum 0.003" engraving bit on Digikey for £30 each.

I tried these:

30 degree 0.1mm, but again very poor cut quality.

Have you not considered straight-shanked end mills?, something like

These are what I've had the best success with in the past.

These are what I have, I'm cutting brass and they die as soon as they touch. Probably me having no experience. But I put a new edge on with diamond disks, I'll be trying again tomorrow with my newly sharpened bits, I have also made sure the edges are bright by finishing on arkansas stone. The best graver finish is one with polished edges. So fingers crossed I edged them right.
