EL60 and BT60 Surface Bench Drilling Bits
Drill Straighter with BDDrill's 60 Series Drill Tools
EL60 and BT60 Drill Bits have a wider hole range when compared to T51 Bits
BDDrill’s EL60 and BT60 drill tools provide twice the penetration rate compared to equivalent size DTH drilling equipment. Better penetration equals better efficiency, saving you time and money.
EL60 and BT60 Drill Bits have the advantage of:
1.5 times the bending stiffness, resulting in straighter hole being drilled.
10% more flushing area for better flushing performance.
The 40% larger cross section makes the rods more durable than T51 Rods.
| Parameter | T51 | EL60 | BT60 |
| Stiffness | 100% | 150% | 150% |
| Flushing Area | 100% | 110% | 110% |
