I used info from hardwood feed and speed table for my sienci 1/2" groove bit:

1000mm/min, 1.5 step down and 17000rpm.

On maple/walnut end grain there is some burning and saw more dust than chips.

Anyone using that bit can tell what f&s they use? Is this because it is end grain maybe?

2nd question. Best way of sanding the groove?

Thanks
