Multi Tip Hollowing Tool
The Multi-tip hollowing
tool is a Robert Sorby
legend and a must-
have for every turner’s
collection. Its massive half
round shank and interchangeable
cutters make this a solid and sturdy tool
capable of multiple applications.
The tool is available in three sizes. The RS200KT
and RS100KT are available with and without
a handle (for unhandled versions ask for the
SOV-RS200 and SOV-RS100 respectively).
The larger SOV-RS300 is offered as an unhandled
version only. Each tool comes with three
Unlike other systems, when used for hollowing,
the RS200KT is used with the flat section on
the tool rest. This eliminates all the rocking and
rolling often associated with hollowing and puts
the turner firmly in control.
For the rapid opening up of an aperture or for
creating a crisp corner in the base of boxes use
the RS212C hollowing tip. If a gentler sweeping
curve is required for example in the bottom
of vases the RS211C’s curved cutting edge is
To under-cut rims of bowls offset the cutter, as
shown in the picture below.
Both tips (RS212C and RS211C) are available
in Excelsior titanium nitride plasma bonded
coatings. Recommended First
Half Round Shank
- �¾ ” flat surface gives total control
during hollowing and scraping
- the round face of the shank is ideal
for shear scraping
HSS cutter for hollowing gentle
curves on bowls (RS211C)
Optional Extra Cutters
allows for easy
undercutting Multi faceted
scraper cutter (RS200C)
HSS cutter for rapid
initial hollowing and
RS239C Cutters not actual size
Fitting the HSS tear-drop shaped cutter
(RS200C) turns the tool into a highly efficient
multi-faceted scraper. The shape of the scraper
cutter converts the tool into a round, half-round
or square scraper suitable for use on the inside
and outside of bowls, platters and hollow forms,
as can be seen in the pictures below.
FOR BEADING AND COVING
Use the flat surface of the shank on the tool
rest to scrape in conventional mode. For shear
scraping, turn the tool round laying the half-
round section of the shank at 45° on the tool
rest. The RS200C is also available in high
performance Excelsior series.
An additional five cutters allow for a variety
of projects from beading and coving to the
ceration of bangles, rings and wheels. All tips
and cutters are sharpened with the aid of a
diamond stone, see page 47.
