647 Cutting Head Assemblies

There are two 647 head assemblies.
A standard cutting head and a special variant with a stabilising hook.

Both are available to order below.

A special version of the head has a stabilising hook to help prevent the head jumping or losing alignment when cutting demanding jobs.

The standard assembly does not have the stabilising hook.
