a new dimension in deep hole drilling.

geometry, 2 spiral coolant
There are numerous deep holes produced in today’s
metalworking industries. Drilling tools predominantly used
nowadays, such as gun drills and HSS drills, usually result in
very long process times. In general, drilling becomes more
and more difficult with increasing drilling depth.

We have focused on this area and pushed the constraints of
tool design further than ever by developing a solid carbide
twist drill with internal coolant supply to meet the demands
of deep hole drilling. These twist drills can be used for most
materials and are very tolerant in terms of the coolant type
and feed applied.
During rotation the chips are forced out of the hole by the drill
helix. This allows the reliable transport of large, jamming chips
such as the ones produced by long-chip materials.
Dry machining or applications using minimum quantity
lubrication are also possible. The result of this development
is XD Technology (patent pending).

X·treme DH / Pilot 180 C –
for high strength materials.
XD Technology
X·treme DH
Deep hole drilling is an issue to which Walter Titex has been extremely devoted
for many years (XD Technology).
Thanks to our continuous development an additional variant has now been
produced that allows improved productivity when working with high-strength
materials. X·treme DH (X·treme Deep High tensile) is a geometry variant
which has been specifically designed for the unique challenges presented by
these materials.
Moreover, these tools are also particularly suitable for machining interrupted

XD Technology
Drilling deep holes is a particularly sophisticated process.
As a general rule: “The smaller and deeper the hole, the greater
the challenge”.
This is why each application in this area must be carefully
coordinated between the user and the tool supplier. The result
is an individual solution for the requirements of our customers.
Alongside the application strategy and the cutting data,
a custom-made special tool is also required.
