Swan Neck Hollowing Tools
Robert Sorby manufactures a wide range of
hollowing tools. Among the most popular is our
range of swan neck tools.
The smallest Robert Sorby swan neck tool is
the 850H at 14” in length. The cutting edge
of this tool is machined from high speed steel
section and is designed to work through the
narrowest of apertures – as small as 3/8”
(10mm).
The larger tool (851H) provides a heavier
section and has the benefit of a replaceable
swivel cutting tip – the General Purpose 851C
cutter. The 851H is designed for end grain use
on shallow depth projects. The (855H) model
uses the same cutting tip but being longer
allows for greater reach.
These tools are designed for hollowing small
and miniature work on branch wood or end
grain timber.
The 24” version (859H) is produced from a
more substantial steel section and is suitable
for both end grain and side grain working.
All of these tools are used with the round bar
directly behind the swan neck (curved area)
against the tool rest. Details on tool size,
minimum attainable apertures and maximum
project depths can be seen in the table below.
