Thread Button 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.
Processing
CNC milling and proprietary heat treatment process
Competitive Advantage
High strength chromium-molybdenum steel with high fatigue strength
and excellent wear resistance
High-grade tungsten carbide inserts
