• Since it uses a thick shaft, it can withstand a large impact load, does not loosen even in reverse rotation, and further prevents the chuck from coming out with a thick inner screw.
• Replacement shaft for drill chuck with thick shaft (1/2-20UNF) specification.
• Shaft load capacity is much higher than that of conventional products.
• Since the inner screw is thick, it is effective in reverse rotation.
• The hex brim is thick, so it is convenient to replace.
• Uses impact resistant steel.
• The heat treatment process is carefully controlled.
