ROTARY DRILLING PICKS
Rotary drilling tool is a supporting tool for construction machinery that makes holes in building foundation engineering. It has good economy, high hardness, good wear resistance, high elastic modulus, high compressive strength and good chemical stability. (Acid, alkali, high temperature oxidation), low impact initial, low expansion coefficient and other characteristics. It is mainly suitable for the construction of sand, clay, silty soil and other soil layers, weathered rock, soft rock, medium hard rock and other rock layers. It is widely used in the construction of various foundations such as cast-in-place piles, continuous walls, and foundation reinforcement.
