Dome Reaming Drill Bit Rock Drill Bit R32 89mm with Spherical Button for Hard Rock Blasting Holes

Reaming rock bit applicable to reaming for first-grade and second-grade larger-diameter hole. It can reduce the sectional area between bit blade and rock hole, also solve the problem of large diameter's low drilling speed in the hard formation with good directive.
reaming bits for quarry are designed to enlarge pilot holes for development rounds,
long hole blasting of drop raises and constructing service holes.
With Pilot adaptors, the drilling direction can be ensured and accurate.

Body Type:
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
