A 3D laser-printed ceramic wear layer that turns the soft steel tooth body into the hardest part of the pick. The body and the tungsten carbide tip now consume at the same rate — so you stop throwing away half-used carbide.
NINGBO, Zhejiang, China — October 12, 2026 — Hengpu (Ningbo) Laser Technology Co., Ltd. today announced the release of its 3D laser-printed ceramic wear layer for engineering cutting picks, a technology designed to solve one of the industry's most expensive inefficiencies: the steel tooth body.
In foundation construction, the performance of rotary drilling picks(Bullet Teeth) can directly influence drilling efficiency, tool consumption, maintenance frequency, and the overall cost of bored pile construction. From high-rise building foundations and bridge piles to metro infrastructure and large-scale civil engineering projects, rotary drilling rigs often encounter a challenging combination of abrasive soil, gravel, weathered rock, fractured formations, and hard rock layers. Under these conditions, conventional cutting picks may experience rapid body wear, carbide tip damage, or premature failure. For contractors, equipment manufacturers, and drilling tool distributors, the challenge is not simply finding a replacement tooth at a competitive price. It is selecting a wear-resistant foundation drilling pick that matches the geological conditions, drilling equipment, and operating requirements.
Cutting picks are essential tools in mining, tunneling, construction, and excavation industries. They are designed to break, cut, and crush hard materials such as rock, coal, minerals, and other geological formations.
