Create a pivot joint for your TeacherGeek projects.

The TeacherGeek Reamer is a tool designed by us to be compatible with our patented splined hole system. When a dowel is pressed into a hole, the spline holds for a tight fit. If a rotating or sliding fit is desired, simply turn the reamer a couple of times in the hole to remove the spline. When you’re building with TeacherGeek components, you should have it.
The TeacherGeek Reamer is one of the most useful tools in our line. It allows you to reduce or remove the spline in the holes found in connector strips, gears, wheels and perpendicular blocks. Removing the spline allows a dowel to spin freely.
