Mollart V12 automotive drilling
The Unique Challenge

Our customer approached Mollart to develop a solution of drilling x 2 23.0mm holes through the galleries of a V12 engine block.

Mollart’s in-house design team set to work designing and developing a fixture solution, to enable the precision drilling of the 23.0mm holes within hole tolerance of ±0.05mm. We also needed to achieve a hole run of less than 0.001’’ per 1.0’’!

This is just one of many unique challenges put forward to Mollart, of which we exceeded customer expectations.  


If you have a project you would like to discuss we have experts on hand who can give you advice and solve those difficult problems you may have. Please contact us with anything relating to deep hole drilling no matter how big or small we can help.
