Using the Variable Alignment to Adjust the Chisel and
Relief Angles
Both models DD500X and DD750X enable you to adjust the
Chisel and Relief Angles of your drill bit. The Chisel and Relief
Angles have a direct effect on the performance of your drill. By
increasing the Relief Angle, you can increase the speed of the
drill in softer materials. To improve the quality of the hole, you
can adjust the drill to be less aggressive. A less-aggressive drill
has lower Chisel and Relief Angles. Your Drill Doctor enables
you to adjust both angles in one setting.
