· Premium Construction: The self-centering lathe chuck body is made of quality cast iron that is strong and sturdy. Several rigorous quality tests have proved that. The lathe chuck is rust-proof, corrosive and skid resistance.

· High-Performance Chuck: Diameter: 5 in / 125 mm; Clamping Range: 0.098"-4.33" / 2.5-110 mm; Jamming Range: 1.5"-5" / 38-125 mm. The 4-jaw lathe chuck comes with two sets of jaws—inside and outside, to extend its holding range, and allows you to handle a wide variety of stock sizes.

· High Precision & Efficiency: The self-centering lathe part contains a delicate bevel gear and pinion gears. They contribute to precise processing progress, bearing tolerance of ≤0.003 in / 0.07 mm.

· Effortless to Operate: The mini lathe chuck is easy to use by turning the ergonomic T chuck key (included in the package). Since the changeover and setting time is cut, your lathe can work with higher efficiency.
