Mite-E-Mark – Double acting air impact marker.

The Mite-E-Mark™ is an extremely compact marking tool. It’s smallest configuration is only 3” long, and has 1” of approach stroke from the retracted position to the point of part marking. The Mite-E-Mark™ now offers an additional option with longer approach stroke. This added feature also has more force. The 2” approach stroke model offers 2200 lbs of impact force at 80 psi.

As systems become more and more automated, Columbia Marking Tools has added more updated technology to the simple air impact marker designs. One of the most recent added options to the Mite-E-Mark™ is the integrated position sensor. This electronic indicator is installed internally and is able to detect when the marker is in the retract position. This option is a favorite among designers of “lights out”, or fully automated applications.

A new cost saving option is also now available for the Mite-E-Mark™. The non-lube version of this air impact marker has permanent lubrication and improved seals. This combination provides a system that no longer requires constant maintenance and additional lubrication.

The Mite-E-Mark™ is one of the many marking machines that Columbia Marking Tools manufactures. Please see for the complete product line. Also displayed on the web are the operation guides and drawings to assist with installation and use of these systems.
