Our 20mm
cemented carbide teeth
are custom engineered for heavy-duty cutting, drilling, and mining operations, solving the common pain points of ordinary cutter teeth such as rapid side wear, short service life, and easy structural damage. Different from conventional single-layer carbide cutter teeth, this upgraded model adopts a dual wear-resistant structure with an additional cemented carbide protective strip on the side, paired with a high-strength 42CrMo quenched and tempered steel body. It perfectly balances ultra-high surface wear resistance, strong structural toughness and impact resistance, becoming a durable core accessory for engineering machinery, mining equipment and road construction tools.
Most
standard carbide teeth
only strengthen the cutting tip, leaving the side wall vulnerable to friction, abrasion and impact erosion during operation. Our
20mm carbide teeth
add an integrated cemented carbide protective strip on the side, which forms a full-range wear-resistant barrier on the tooth side. This innovative structure effectively resists sand, stone, soil and other abrasive mediums’ long-term scouring, greatly reducing side thinning, chipping and deformation. The overall wear resistance is improved by more than 35% compared with ordinary models, significantly extending the service cycle of a single cutter tooth.
The cutter tooth base adopts premium 42CrMo chrome-molybdenum alloy steel, which undergoes strict integral quenching and high-temperature tempering heat treatment. Compared with ordinary carbon steel and low-alloy steel substrates, 42CrMo material features excellent hardenability, high fatigue resistance and no temper brittleness. It maintains stable structural strength under high-load, frequent impact and alternating stress working conditions. With a tensile strength of ≥1080MPa and yield strength of ≥930MPa, the matrix effectively absorbs instantaneous impact force, avoiding tooth body breakage, cracking and falling off, ensuring stable operation in harsh working environments.
Application Scenarios: Mining, Road Construction, Drilling Engineering, Mechanical Cutting.
