DESCRIPTION
■ Introduction
UNIMATE has the ability to manufacture and supply 8½" (215.9mm) and 12 1/4" (311mm) roller bits for hard rock drilling. Moreoever, we can also supply used roller bits in good condition if requested by the customer.
Metal sealed roller bits :
a) Adopted high-speed bearing metal sealed technology, long working life under the screw drilling condition.
b) High efficiency cutting edge and structure to improve drilling speed.
c) Cutter shell self-protection shape to reduce abrasion of detritus and unbreakable rock.
d) Best choice for directional well, horizontal drainhole and horizontal branch wells.
