This center punch is perfect for setting tube rivets and for marking an indentation for drilling.
To prevent your drill bit from moving off the mark when drilling, line up the tip of the punch where the hole will go. Strike the punch with a 1lb Brass Head Mallet. This will leave an indentation that you can place your drill bit into to keep it steady while drilling.
You can also use the center punch as a dot or period in case your lose or wear out the one in the letter stamp sets.
