Satisfied customers

“We have been using LACH’s diamond tipped inserts and end mills for over 12 years. Their tooling is always of the highest quality, order after order.  
So much in fact, we have been able to set up entire processes around their tooling which has increased production and efficiencies substantially. Processes that we were unable to accomplish without Lach’s tools. 
We regularly see upwards of 50x tool life increase over standard carbide tooling.” 
Bryan Tyler, Mersen, USA
“We are highly convinced with the quality of your grinding wheels. In fact, we have one of your grinding wheels in use since 2005. Now, 18 years later, we need replacement.”  
Heike Kopp, Schneider Schreibgeräte GmbH, Germany
