ALL CUTTERS ARE AVAILABLE INDIVIDUALLY AS DETAILED BELOW
Round Cutter Detail Point Cutter Square Cutter
A general purpose cutter used for rapid removal
of material both inside and outside of bowls and
hollow forms – works equally efficiently on spindle
work. In shear scraping mode it will
produce an extremely fine finish
requiring little or no sanding. Contrary to its description this cutter is the first
choice when roughing square to round both quickly
and safely when turning between centres (spindle
work) Also extremely useful for creating fine detail
on spindle and bowl work. .
Shear scraping is not
advised with this cutter. Used for generating square shoulders on tenons
where a turned part is to be assembled in to a hole
– a chair leg is a good example. This cutter is useful
on the outside of a round form as
well as long straight sections on
spindle work. A superior finish can
be achieved by making your final
cuts in shear scraping mode.

French Curve Teardrop Inside / Outside Mushroom
This cutter is ideal for scraping or shear scraping
inside forms. Ideally suited for that finishing cut
on egg cups, goblets and
round bottomed boxes. Use the straight side for scraping and shear
scraping outside forms. The curved edge is
excellent for scraping
and shear scraping inside
forms. As the name suggests this cutter is designed for
undercutting mushroom shapes,
p , but is also ideal
for hollowing out small
forms.

This cutter is designed to create parallel side walls
and 90 degree corners in boxes. It also creates
dovetails and tenons to
mount timber on scroll
chucks.

projects completed using TurnMaster
HARD, HARDER, HARDEST, SHARP, SHARPER, SHARPEST
Tungsten Carbide:
Makes light work of the tough materials and is an extremely hard wearing and
long lasting material. Although designed as a throwaway item it can be
sharpened on specialist equipment such as Robert Sorby’s ProEdge when
fitted with a diamond belt. (Made much easier with the aid of the tip holder, RSTM-TH)
• Sharpens to 0.7 - microns • Hardness: 90 RC • Material: micro grade tungsten carbide
High Speed Steel (HSS):
This super fine grain structure will provide a razor sharp edge. The result is a
superior finish to your turning projects and less need for sanding. Can easily
be sharpened on traditional sharpening machines such as bench grinders or
on the Robert Sorby ProEdge. (Made much easier with the aid of the tip holder, RSTM-TH)
• Sharpens to 0.2 - 0.4 microns • Hardness: 62RC • Material: M2 HSS
Titanium Nitride (TiN) plasma bonded coating:
TiN is bonded onto quality HSS. It provides the same advantages as
HSS whilst enhancing the cutting life close to that of tungsten carbide.
Use the same traditional sharpening equipment used for HSS.
• Sharpens to 0.15 - 0.2 microns • Hardness of coating: Up to 85 RC • Material: Titanium nitride on M2 HSS
