All MHD-XL rigs can be outfitted with:
Kelly Bars power your drill’s torque and depth. Round Kelly Bars use a manual locking system and perform best in hard or rocky ground. Square Kelly Bars feature a friction lock and are ideal for softer soils, offering quicker alignment and greater flexibility.
Spiradrill rigs support both, so you can match your bar to the job.
