Tungsten Carbide Buttons for Extreme Rock Drilling

Engineered for high-impact, high-abrasion drilling environments, Retop’s tungsten carbide buttons deliver exceptional hardness, fracture toughness, and long tool life for mining, construction, and oilfield applications.

Product Description

Tungsten carbide buttons are sintered inserts used in drill bits and cutting heads for high-impact applications like mining, tunneling, and petroleum exploration. Made from submicron WC grains and high cobalt content binders, these buttons offer unmatched hardness and toughness, minimizing wear and tool failure even under extreme loads.

Carbide buttons are widely applied in down-the-hole (DTH) bits, tricone bits, percussion drills, and rotary drilling tools. They are essential in industries such as mining, oil and gas, quarrying, construction, and geological exploration, especially for hard rock and abrasive formations.

Features
