Three-Jaw Lathe Chuck with Self-Centering Grip, 125 mm Diameter for Speeds up to 3000 RPM, Silver with Tightening Key
You already have the maximum available quantity in your cart.
This chuck, sized at 125 mm, or 12.5 cm, is among the clamping devices for lathes that process even thicker workpieces. The three jaws move down the spiral together, ensuring that the workpiece remains aligned with the spindle axis after tightening and does not require manual adjustment. Both the body and the moving parts are made from a combination of cast iron and steel, where the cast iron provides rigidity to the chuck, and the steel takes on the stress at the gripping point. The graduated jaws are visible at the front, with individual levels accommodating various diameters. The figure of 3000 revolutions per minute stamped on the casing defines the operational range in which the chuck is used.
- Size 125 mm – a diameter of 12.5 cm provides ample space for clamping larger pieces while remaining within the dimensions compatible with standard workshop lathes, fitting even smaller spindles
- Parallel Jaw Movement – all three jaws move down the spiral simultaneously, aligning the workpiece axis with the centre of rotation automatically, which reduces the time needed to clamp each subsequent piece
- Graduated Seating Surfaces – each jaw features several levels, allowing the grip to fit both thinner and thicker workpieces without adjustment, enabling the processing of various workpieces in succession
- Operational Speed – 3000 revolutions per minute is the value marked directly on the body, which can be used to set the machine speed before starting machining
- Material Composition – the cast iron part forms the base of the chuck, while the steel components pertain to the moving elements that bear the gripping force and wear during each jaw movement
- Operation with Key – the included adjustable key is inserted into the hole on the casing, and by turning it, the jaws move towards the centre or open outwards, so no additional tools are needed for operation
Package Contents:
- 1x chuck
- 1x adjustable key
The larger diameter of the chuck expands the range of components that can be processed on the lathe, as the grip can accommodate pieces that a smaller chuck cannot. It is also essential that the chuck matches the machine, so it is advisable to compare the flange size and the space between the spindle and the support before purchasing. Self-Centering Grip with Three Jaws reduces preparation time, as the operator only tightens the key, and the workpiece finds its centre automatically. The graduated shape of the jaws covers a wide range of diameters, allowing both shafts and larger discs to be clamped during a single operation without reaching for different accessories. The silver finish with a smooth casing surface easily sheds chips, and marks from work are less noticeable, which is beneficial for a chuck that remains permanently mounted on the machine. Before each clamping, it is sufficient to run a brush through the grooves and remove any remnants from previous machining, ensuring the jaws seat fully. The chuck then holds the workpiece firmly throughout the cutting process, and the turned surface emerges evenly around the entire circumference. After completing the work, the jaws are loosened, and the key is set aside by the machine, keeping it handy for the next clamping without needing to search among other tools.
