I had been successfully cutting ornaments from 1/4" baltic birch and then I started experimenting with raising the speeds because it was taking almost a day to do a single piece. Now I am getting pretty bad splintering on the edges and I can’t seem to get back to a clean cut cranking things down to 50 ips.
Using a chinese 1.5 mm bit with a cross-hatch blade (i.e. looking at the side it is an X pattern) so not really a downcut. Swapped bits but it doesn’t seem to be an issue with worn cutters.
Anybody have a good F&S setting/bit recommendation for this?
