Description - Narex Vhu 2 1/8" Instruction Manual

We are confident that the Vhu 21/8", 31/8",Vhu 47/8" and Vhu 6 ¼ " universal boring heads will
enable you to perform the most accurate and intricate operations on your boring machines.
The Vhu 21/8", 31/8", Vhu 47/8" and Vhu 6 ¼ " universal boring heads enable a large number
of various operations which, however, require a wide choice of tools, which – in the majority of
cases – will not be utilised. Therefore, along with each Vhu boring head the above specified
tool bits are supplied as standard accessories. Tools for recessing, thread cutting and other
special jobs can be made by grinding from semi – products 5/16" x 6/16" x L (for Vhu 21/8",
31/8") or 3/8" x 3/8" x L (for Vhu 47/8" and Vhu 6 ¼ ").
By using two reducing sleeves supplied as standard accessories it is possible to work with all
types of standard tools with a circular cross section shank of 3/4" and 5/8" dia.
