How to Eliminate “Wag”
What is “wag”? – Wag is the radial movement of the drill tip due to the movement of the drill stop within the guide tube and movement of the drill within the drill stop. The amount of wag is correlated with guide height and drill length.
Wag increases with:
-Proportion of drill length not within tube
-Decreasing length of drill stop
Solution – short drill in long drill stop
