In underground mining and tunnel construction, the performance of roadheader cutting picks directly affects excavation efficiency, cutting head maintenance, tool consumption, and overall operating cost. When a roadheader works continuously in abrasive rock, mixed ground, or hard geological formations, conventional cutting tools can experience rapid carbide wear, tip breakage, shank abrasion, or premature failure. For this reason, selecting the right roadheader picks is not simply a matter of matching dimensions. The carbide grade, pick geometry, steel body strength, brazing quality, surface wear protection, and cutting conditions all play an important role in determining tool performance. At Hengpu Laser, we focus on developing high-performance roadheader cutting picks and tunneling picks by combining advanced carbide technology with our proprietary laser-based metal-ceramic wear-resistant technology.
Stop Losing Money to Premature WearIn the demanding world of road construction and rehabilitation, downtime is the enemy. For decades, the industry has struggled with a persistent bottleneck: premature wear of the bit body.While tungsten carbide tips often receive the spotlight, the harsh reality i
In underground coal mining and soft-to-hard rock tunneling, continuous miners, longwall shearers, and roadheader machines operate in some of the most punishing mechanical environments on earth. At the business end of these massive, multi-ton cutting drums and cutter heads are hundreds of conical cut
Executive Summary: In cold planing and pavement recycling, road milling picks are critical wear parts directly impacting machine downtime, cutting efficiency, and cost per square meter. This comprehensive guide breaks down the key technical elements of premium milling teeth—including tungsten carbide tip formulations, forged body heat-treatment, and clamping sleeve dynamics. Readers will learn how to select the right pick geometry for different pavement conditions (asphalt, concrete, micro-milling) and implement site-proven maintenance strategies to prevent premature breakage, minimize toolholder wear, and maximize operational ROI.
Global infrastructure development is entering a new stage. Governments and private investors are financing roads, railways, tunnels, mines, water systems, energy facilities, and urban transportation networks to support economic growth and replace aging assets.
Cutting picks used in mining, road construction, tunneling, and foundation drilling must work under severe mechanical stress. During operation, the carbide tip may repeatedly strike hard rock, mineral inclusions, concrete, or uneven working surfaces.
