Technology Update
WITHIN a year of the launch of Tiger.tec
Silver, tooling company Walter GB has
expanded the range of indexable inserts
to embrace all its milling tools for steel and
cast iron machining.
Next on the company’s development
agenda are Tiger.tec Silver inserts for
drilling and turning, and extensions to the
current universal grade of WKP35S that
will include grades with higher levels of
toughness and hardness.
Walter GB states that users are
reporting tool life performance increases
of up to 100 per cent with Tiger.tec Silver,
which features a surface treatment that
reduces the in-cycle machining stresses
of both wet and dry applications, due to
its balanced combination of a high level
of toughness and maximised hardness.
The result is an insert that will compensate
for any brittleness that may develop as a
result of the CVD coating process.
The CVD-Al 2O3 grade coating counters
any influence from thermal shock that can
lead to thermal cracking at the cutting
edge, and minimises tribochemical wear
on the flank face. These are key areas that
can lead to premature insert failure.
The Tiger.tec Silver designation reflects
the insert’s two-tone finish of glossy silver
on its flank face and black on the rake angle
face. The colour combination provides a
practical indication of wear.

Silver inserts cover tube milling tools
BESWICK Engineering Co manufactures
the metal-handled TC-1 tube and hose
cutter – a precision tool aimed at those
who are dissatisfied with the performance
of plastic-handled cutters.
The cutter is simple to use, makes
square cuts, and saves time. It is made
from chrome plated metal for strength,
and a plastic coating is applied to the
handles to improve feel. The V-shaped
head ensures straight cuts and prevents
jagged edges.
The TC-1 will cut many types of plastic
tubing and hose up to approximately 1"
OD. Additionally, the blade indexes to
provide two cutting edges instead of just
one. If the blade becomes damaged or dull,
a replacement blade package is available
with ten new blades.
