Non-Thru-Hole | Two JAW CHUCK

2M 2 jaw chuck is a device used in machining and turning operations to hold and secure a workpiece on a lathe or similar machine tool. It is called a "two-jaw" chuck because it consists of two jaws that can be adjusted to grip and center the workpiece.

Key features and functions of AUTOGRIP® 2 jaw lathe chuck:

  • The primary function of a 2 jaw power chuck is to securely grip the workpiece. The jaws of the chuck can be adjusted independently to hold the workpiece with a firm and concentric grip.
  • WEDGE-HOOK type two jaw chuck, and extra-long jaw stroke.
  • Matching surfaces of all parts hardened, ground, and lubricated directly.
  • High rigidity and high repeatability precision.
  • Deliver up to 20% more speed, gripping force, and bore size when compared to conventional chucks.
  • Allowing for rapid removal and replacement of workpieces. This feature saves time and enhances efficiency in machining processes.
  • Can be flipped around to accommodate different types and sizes of workpieces which increases flexibility and adaptability when machining various parts.
