When you have to cut through a rock-solid wall, you need proven performance, not flimsy claims. We supply rock tools set the standard for the HDD industry, starting with the legendary Melfred Borzall Eagle Claw, the go-to rock bit for experienced drillers who don’t mess around. QDS stocks an entire line of rock tools that are engineered to make you unstoppable!
ABOUT Rock Bits & Hole Openers
Less talk, more drilling rock.
Iron Fist Cobble Bit
Ideal for drilling in cobbles and rocky conditions
Challenging cobble bore? Not anymore. The Iron Fist packs a major punch in cobble and loose rock conditions and is designed to be easily and inexpensively rebuilt, reducing your tooling costs. Bam.
Performance Features:
Main carbide cutters positioned to allow for “rocking” the bit through rocks
Compact cutters are less likely to hang up on cobbles
Balanced cutters for downhole stability
Contoured design
1/4″ recessed water holes to prevent clogging
Built-in check valve to minimize chance of clogging
Wrench flats for easy removal
Capable of doing direct pullbacks with the Iron Eye pullback device
Available cutting sizes:
4″ – 6″

Eagle Claws & Replacement Cutters
The #1 bit for hard, rocky soil conditions.
The newly redesigned Eagle Claw SD™ bit is made for hard, rocky soil conditions. The hardened steel carbide cutter teeth on the front of the bit are designed to cut through the hardest soils with embedded chunky hardfacing.
The interchangeable cutter teeth accommodate a wide variety of job conditions and has integrated dome carbide blocks into the body to give greater wear protection and cutting power. Added conical carbides on the upper cutting face add more aggression to the bit’s cutting power. The dome carbide blocks on the opposite side of the body also help transfer more power to the cutting surface as they push against the wall pack during rotation downhole.
Performance Features:
Unique balanced cutting design improves cutting efficiency
Aggressive tri-tooth carbide cutting action gets through the hardest conditions
Smooth running with minimal vibration to drill stem and drill rig
Dome carbide buttons minimize wear on bit body and push against the wall pack
Quickly and easily change out carbide cutter teeth
Easily threads on to a side-load or high-flow housing
Steering face has conical shape for quicker reaction to directional “pushes”
Available sizes:
Available in several cut sizes for rigs from 7,000 to 200,000 lbs.

Rock-it Mud Motors
Built for HDD Performance Performance Features:
High performance mud motor designed specifically for HDD
Can be operated at a slower speed for more compatibilty with tri-cone bits
High torque-to-flow ratio means more drilling power with less fluid
High quality internal parts results in more drilling time before regular maintenance is required
Mud-Motor rentals available
Bearing packs are designed to be completely sealed
Rotors and stators are designed for HDD. They are shorter in length to help with the steering of the motor. All stators are manufactured with a new “hard” nitile rubber resulting in more power from the motor.
Built tough to withstand the harsh conditions of horizontal drilling. Stator tube walls are twice as thick as other brands for maximum durability.
