What is the Pit Bull™ Design?
The Melfred Borzall Engineers have developed a way to relieve your stress of breaking off a bit downhole. The Pit Bull Blades and Housing design utilize machined dowel pins that can be inserted by hand into the steer-face of the bolt-on housing. Those same dowel pins match up to holes on the directional blade being mated up. This simple feature adds over 100% shear load capacity to your blade bolts since they are no longer taking the force on rotation. This will not only make your bolts last longer, you never have to worry about them rattling loose, or backing out either.
