Install the reamer on the prepared seating of the tool holder. Screw the spindle with conical guide, spring and thrust bearing into the tool holder.


First, remove the conical guide from the spindle. Insert the tool from above into the head tube of the frame. Put the conical guide on the spindle again and apply pressure with the spring. Rotate the tool clockwise. Use cutting oil while working. Continue to rotate clockwise, while taking the tool out of the head tube. Repeat the above steps to ream the bottom side of the head tube.
