After years of fumbling through a drawer looking for the right drill bit, I decided to devise a better solution. The result was the drawer inserts you see here.
The bits are organised neatly in trays with shallow slots to hold them in place. The two-level, sliding trays allow me to quickly access any bit I need.
The slots for the twist bits were made using a bowl bit at the router table. I used a dado blade to cut slots for the Forstner bits. Now my bits are always at the ready.
