Lathe chuck - Chuck - Jaw chuck

What are lathe chucks, chucks or jaw chucks?

Chucks are devices that hold, fix and centre tools such as drills, milling cutters on drills or the workpiece to be machined on a lathe. In our online shop you will find 2- to 6-jaw chucks!

Which number of jaws should I choose?

Basically, the more jaws the higher the stability. However, this is not always absolutely necessary. If you only want to machine a smaller workpiece, the classic 3-jaw chuck is sufficient in any case. For large workpieces, a larger number of jaws should be selected to ensure stability.
If the material bars to be machined are not round, e.g. squares or hexagons, a 4- or 6-jaw chuck is also required.
A 2-jaw chuck is suitable for holding polygonal or shaped parts which cannot be clamped with one of the other number of jaws lathe chucks.

Which jaw chuck material should I choose?

You are not sure if you should buy a jaw chuck made of steel or cast iron?
It depends on what and how much you want to machine with it.

Steel jaw chucks are a little more expensive, but the advantage is that they are much more prone to wear and therefore have a longer life. Steel is generally harder than cast iron and usually also hardened (tempered), which results in greater strength. As a result, steel jaw chucks are suitable for much higher speeds and have better concentricity.

If you work in the lower speed range and not industrially (i.e. no continuous production), a cast iron jaw chuck is completely sufficient. Here too, there are variants which have good concentricity properties. We will be pleased to advise you in your decision.
