Threaded Button Bits
Request a Quote
Threaded drill bits are mainly used on hydraulic or air-powered rock drilling machines. They need to connect to drill rods before the whole assembly can be mounted on drilling equipment.
Yanggu threaded drill bits are made of imported quality alloy steel. We use advanced shrink-fitting techniques to press-fit conical inserts into pre-drilled holes in the bit. These conical inserts are raised dots that can be seen on the surface of the bit.
