Ay-Yıldız Engineering Cross Bits are high-performance drilling tools designed for tunneling, mining, and rock excavation applications. Their cross-shaped tungsten carbide buttons deliver balanced impact on the rock surface, increasing fragmentation efficiency and ensuring faster, more effective drilling. Thanks to their durable structure and strong wear resistance, they maintain stable performance even under intensive use.
The Cross Bit design is optimized to perform efficiently in various ground conditions. It provides high drilling performance in both medium-hard and hard rock formations. During drilling, the smooth evacuation of cuttings helps reduce wear and extends the bit’s service life. Ay-Yıldız Engineering offers different diameters and button hardness options, allowing compatibility with a wide range of drilling machines.
Ay-Yıldız Engineering Cross Bits provide reliable, long-lasting, and high-performance drilling solutions, ensuring safe and efficient operations in tunneling, mining, and rock excavation projects.
