Strategic placement of cutters on the upside of each blade, to allow backreaming in tight spots, reduces the potential of “bit sticking” while pulling out of the hole. Allows a degree of backreaming, sufficient to condition a borehole without major risk of gauge pad wear

Gauge pad configuration for very abrasive formation. This additional diamond volume will help prevent the gauge pads from going under gauge.
