R25 type of bit is well known for its high wear resistance on
medium-hard to hard abrasive rock formations (between 200 Mpa to
260 Mpa compressive strength).
Featuring spherical tungsten carbide inserts that are known to have
strong configuration against carbide fracture.
The bit face design is ideal for medium-hard to hard abrasive rock
Applications
Used in small hole drilling.
