This charts will help you to decide which size drill bit to use in your scrolling. There is no one to one correlation between blade sizes and drill bit sizes because there is so much variation in the thickness of blades from one manufacturer to the next. Compare the thickness of the blade that you want to use with the diameter of the hole made by each of these drill bits to determine which would work best in your application.

If you would like to print this  page for a handy reference in your shop, try setting your paper to print in "landscape" rather than "portrait" so that the entire chart is printed for you. Or, we have prepared the same chart in Adobe™ format. You may save or print the chart easily from that format by clicking here.
