Bowl bits are the best router bit for tray making. With the extra-long flute length and bowl radius of 0.375", it can remove large amounts of material in a single pass. The 'super-shear' blade is designed to leave exceptionally clean cuts at higher feed rates.

The effective cutting depth is usually 1/2″. Quarter inch diameter bits are good for cutting thicker materials, like wood, and removing more material per pass. The effective cutting depth is usually 1″.

The lead time for CNC machining can vary widely depending on the factors listed above. However, in general, most orders take anywhere from a few days to a few weeks. The complexity and material of the part typically play the most significant role in determining lead time.
