GK100 Chuck

The Axminster Discovery GK100 chuck is ideal for a variety of lathe models but ideally more suited medium sized lathes. The 100 refers to the chuck diameter of 100mm or 4 inches.

The chuck, jaws and accessories are all precision engineered to ensure they deliver CNC accurate results. The GK100 chuck features a geared key, stainless-steel body and interchangeable backplate for effective corrosion resistance. These chucks won’t rust, either from condensation in a cold workshop or the sap from green wood. Stainless steel body is machined to exact tolerances for a perfect fit of both jaws and lathe spindle.

The interchangeable backplate allows you to keep your chuck body when upgrading your lathe, saving you time and money; simply choose the suitable backplate for your new lathe thread and attach to the chuck body. Upon first purchase of your chuck, choose the correct thread for your lathe.

The GK100 chuck features our latest SafetyJaw accessory mounting jaws. Pair the chuck with our great range of stainless steel jaws to suit your project needs.

Available in sizes 1” x 8 tpi, 1.1/4” x 8 tpi, 3/4” x 16 tpi and M33 x 3.5mm.
