„Innovation is our future.“
Sascha Tschiggfrei, CEO
The Future
has begun
As a global market leader, we manufacture technologically
advanced high precision tool holders for turning centers and
swiss type lathes that are known for high performance and
long life-time.
Using our new “smart” technology, our customers will be able to
intelligently optimize and monitor their processes in the future.
State-of-the-art technology for maximum
productivity. With this claim, WTO develops
and produces superior precision tool holders
in terms of technology and quality.
Used intelligently, processes are optimized and
production becomes more productive.
WTO Driven Precision Tool Holders equipped
with innovative „smart“ technology enable
intelligent online process monitoring.
“Consistent development -
always one step ahead.

High Tech
Made in Germany
From the technical design to the finished product
we make no compromises when it comes to
manufacturing our high precision tool holders.
Permanent investment in state-of-the-art
production technologies, high quality standards
and a large manufacturing depth.
Our products are in use worldwide, wherever
precision parts are manufactured on turning
centers with high productivity.
„Our employees don‘t work for WTO.
They work for the success of our customers.“
Patrick Diener, Vice President WTO USA
Motivated employees are the basis for 100 % consistent
customer focus.
WTO offers its employees a state-of-the-art working environ-
ment to work independently and ensures highly motivated
employees in a family-owned technology company.
To a large extent, WTO relies on its own highly qualified
employees in order to achieve high quality standards.

The quick change system from Sandvik Coro-
mant for fastest tool setup time. Faster return
on investment.
Coromant Capto® is a modular quick change
system certified according to ISO 26623.
It combines high rigidity with high flexibility
in one system.
Short adapters
available from WTO
For precision driven tool holders with Coromant Capto
®
the use of short adapters with no gripper groove
lead to significant advantages: More available cut-
ting tool length, higher accuracy and higher stability.
The globally available quick change system
for turning centers is universally applicable
for turning, drilling and milling.
High investment security through ISO standard.
