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.”

"Being our first step into PCD tooling, we didn’t know what to expect, but LACH DIAMOND did a fantastic job and helped us utilize the PCD tools to their full potential. The parts that used to take nearly 6 hours per cycle, have been reduced to only 35 minutes. Tool wear has greatly gone down as well, partially due to the PCD material, but also the tool pathing changes we could make due to the custom tooling they designed."

"We are highly convinced with the quality of LACH DIAMANT's grinding wheels. In fact, we have one of your grinding wheels in use since 2005. Now, 18 years later, we need replacement."

“We were originally running parts with solid carbide tools and were having issues going through excessive amounts of tooling, along with long cycle times, since coolant wasn’t an option. […]
