Our jeweler’s twist drill organizer and dispenser is designed to hold industry-standard 3/32" shank drill bits.  Labeled with millimeter sizes and also features one compartment labeled as “Mixed” for when you find that single drill bit and do not know what size it is, or you do not want to put it back with the new drill bits. One additional compartment is labeled "Used". The last compartment is to “close” the container and have all the drill bits safe and secure. On the side of the container there are openings to allow the user to see if there are any drill bits inside the compartment.  Has a total of 22 holes/compartments that accommodate drill bit sizes of .50 – 23mm and has a diameter of 2-7/8” and a height of 2-3/4”.   Made in USA
