The holder made of high strength zinc alloy is connected perpendicularly to the shank incorporated with a ball. With a grease pocket formed on the top and bottom of the spherical area, this model achieves high lubricity and high wear resistance.
The holder is connected in perpendicular to the shank, which comprises a male thread specially welded with a highly accurate steel ball. With a grease pocket formed on the top and bottom of the spherical area, this model achieves high lubricity and high wear resistance. Use of the A-1 alloy in the holder significantly reduces the weight.
