Moderately weathered limestone, argillaceous limestone, highly weathered dolomite, silicified limestone, and schist.
1.Low-Cobalt Extra-Coarse Tungsten Carbide Main Alloy:Ø30mm large-alloy blank body, specifically engineered for hard rock formations. Utilizing innovative materials to enhance rock-breaking efficiency and extend service life compared to conventional alloys.
2.High-Strength Tough Shank：The pick body is manufactured through warm extrusion forging combined with precision heat treatment, resulting in higher material density and enhanced wear resistance. Each unit comes standard with anti-loosening retaining springs.
3.Ultra-High Vacuum Precision Welding：Achieves high-strength bonding between alloy and blank body, preventing carbide precipitation and weld seam weakening, thereby enhancing the pick's spalling resistance under impact loading.
4.Hydrodynamic Pick Body Design：Accelerates pick rotation and reduces uneven wear.
