The Live Event

Be there live from Dec. 16, 2021, and join us in finding out "How long will our IGUANA tool run?"

One tool, one machine, and the task of covering milling paths.

To find out, we will produce event coins from copper blanks on our KERN milling machine with just one single double-edged 1 mm ball nose end mill of the IGUANA family until the tool wears out and the coins no longer have the required quality. Of course, under the strict observation of live cameras throughout.

Look forward to changing coin designs, exclusive interviews and insights into our partner companies, ZECHA and many more surprises.

Visit our stream also on as well as on the homepages of all our participating partners. There you will also find all information about the event.

Challenge accepted - do you?

Charity Auction of the Christmas and New Year's coins 

One challenge follows the next: Our IGUANA tool has passed the first test with flying colors and milled 28 copper coins. Now it is your turn.

With the closing on Friday, January 14, 2022, you can bid for the live milled coins from the IGUANA MILLING CHALLENGE for a good cause during the one-week online auction.

The Christmas and New Year's Eve coin as well as the AlienTools New Year's medal 2022 were auctioned to the highest bidders: Congratulations on your very own coins!

The proceeds from the auction will go to the Sterneninsel e.V. children's and youth hospice service in Pforzheim and Enkreis.

Press report 


Multi-cutters in the small diameter range with sharp cutting edges (R=1µm) and highly wear-resistant, closed diamond coating - that is the IGUANA tool family from ZECHA.

Especially when machining highly abrasive materials, non-ferrous metals or copper in a wide variety of industries, many a tool reaches its limits. Thanks to the award-winning IGUANA technology, cutting forces are significantly reduced and tool life and surface qualities are significantly increased compared to previous diamond-coated tools.

Brand new to the IGUANA Milling Challenge is the new 935 series, which has been specially developed for producing the finest surfaces in non-ferrous materials. With their mold-making dimensions, the double-edged ball cutters and double- and triple-edged torus cutters are ideally suited for the production of copper electrodes. Due to an exceptional cutting edge setback, the tools are particularly low-vibration and minimize cutting pressure.



AlienTools was born as a joint-venture in order to bring Zecha quality tools into the dental industry with a fresh, new look.

Based in Berlin Germany, the team at AlienTools quickly built a well-known brand by taking the top-quality tools from the Zecha portfolio and focusing on the digital experience in order to maximize the ease of working directly with the manufacturer. This means not only having a webshop and being active on social media, but usings today’s technology to maximize the enjoyment of working with AlienTools in the form of loayalty programs, affiliate programs, etc.


In the first 2 years of the project, AlienTools sold directly to customers in over 50 countries. With this project showing that customers were eager for next generation of partnerships, they have just recently expanded and launched their industrial line, bringing a fresh new face to the form and die industry.



ZECHA Hartmetall-Werkzeugfabrikation GmbH has been a pioneer and trendsetter in the field of micro cutting, blanking and forming tools for over half a century. The company's origins in the chronograph industry can be seen not only in its uncompromising specialisation in the production of miniature tools of the highest precision, but also in its special tool solutions.

Precision and quality are key for the international employment in different industries, such as, for example, in medical and dental technology, the chronograph industry, automotive industry, or in tool and mould making. Experts in the company's own research and development department are constantly developing ground breaking geometries and tools for sophisticated applications and cutting-edge materials.

In addition, tool reproducibility is also guaranteed even for years on account of the life number stamped at the end of the shaft of every tool.

Modern CNC machines, high-end measuring and testing technologies and carefully selected hard metals from leading manufacturers as well as an intensive cooperation with our customers and partners ensure the exceptional perfection of our Tools.


Since founding the company in 1997, Daniel Gruber, owner of CIMTRODE GmbH, has been working intensely on driving graphite machining forward. CIMTRODE, which serves the tool and moulding industry, has developed over the years from a manufacturer to a renowned European graphite specialist and innovator.

At the start there was the “All-Inclusive Electrode” made from graphite. We are proud to say that our leading role in this field has contributed to making electrodes extremely popular in manufacturing. In the meantime, the Cimtrode concept has gained an excellent reputation as a technology leader and our blue boxes with the distinctive label can be found in many production halls today.

Based on our many years’ experience with graphite machining, we have created additional innovative & specialized products “from the user for the user.” Products such as the SEAGULL precision cutter featuring cost-saving cutting pressure optimization, or the optical control system C-VIEW. When developing these products we have always focused on the benefits to the user, with our own experiences as a guideline.

We continuously work to deliver first-class, innovative solutions to our customers, from users for users, thereby contributing to the competitiveness of the tool and moulding industry in today’s world.
