Go slow so you don't melt the plastic or the thread. Every so often roll the screwdriver so your using fresh thread to make your cuts. You'll be surprised at the control and smoothness of the cut. It cuts so well that I throw the molded hatch in my parts bin, or like on my KT, use the same cut hatch to make it open.

Hope this helps.
