Drilling pilot holes used to involve finding the screw chart to remember the right size, then squinting at the bits until I found the right size.
Now I use a simple color coding system so I can instantly grab the right bit and get to work. I borrowed three shades of nail polish, and painted the tip of my bits. Don’t glop it on too heavily or you could clog the flutes of the bit. One color identifies each size I use most: 3/32" for no. 6 screws, 7/64" for no. 8, and 1/8" for no. 10 screws.
Tape a piece of white paper with the color key to the inside lid of your drill bit box so you’ll remember the code.
