High Grade Material Reaming Drill Bit R32 76mm Spherical Button Drill Bit with Special Designed Flushing Holes
Skirt selection:
Standard Skirt
Typically smaller than the head diameter to avoid cuttings and the rock wall, therefore optimizing hole flushing.
Heavy Duty Skirt
A variation on the standard skirt design, available for very abrasive conditions. The heavy duty skirt has added wear material towards the front of the skirt to protect the bit against abrasive cuttings.
Retrac Skirt
Designed to improve hole straightness, as well as to assist in retrieval of the drill string. The splines will also improve the hole flushing characteristics of the bit due to the chip ways between the splines
