Which blade is used as the base for
RazorTip?
DoubleHard material is the base for blades of 32mm
and 38mm width and SilverTip material is used for
45mm, 50mm and 75mm wide blades.
Are the teeth of the base blade
hardened before application of Stellite
so that the blade can be used as a
'normal' blade when the Stellite has
been completely ground away?
No, this is not possible with the set pattern being
applied. Enough quantity of Stellite is applied to
allow the blade to be sharpened several times. When
the Stellite is worn away, some customers do keep
the blades to use on logs that are likely to be
contaminated with metal, to avoid the risk of
damaging their normal blades. Where the Stellite
has been applied to DoubleHard base material, the
blades can be used in normal cutting operations and
are equivalent to Wood-Mizer's 'professional' (nonhardened) range, which has served many customers
very well for many years.
Is the kerf of RazorTip blades greater
than the kerf of DoubleHard and
SilverTip blades because of the
thickness of Stellite on teeth?
The Stellite overhangs the side of the tooth by
approximately 0.3mm, but the kerf is the same as
standard blades. The sides of the Stellite are ground
straight to allow the customer to re-set the teeth and
maintain the kerf.
This is a great advantage over blades where the
Stellite is applied to unset teeth and the Stellite itself
is shaped to provide the kerf width, because this type
of blade loses performanc
