Mayhew Junior Friction Welded Rod 2 7/8" Shoulder 79mm 2 - 3/8" REG

Advantages:

1, Workmanship: Taper rod with carburize treatment.

2, Tapered drill rods have a tough life, transferring the percussion energy from rock drill to drilling bit and then into the rock. They’re also subjected to high bending stress, not to mention corrosive water in the flushing hole.
