Our boring is done using a Rottler machine.

Sonic testing (which measures bore thickness) can be performed previous to boring to check for any core shift, which results in thin sections in your bore. If needed we can offset the bore, within reason, to minimise removal of material at the thinner sections of the bore so as to maintain maximum wall thickness.

We can also sleeve your block if needed.

If you are looking for the highest quality cylinder boring Duggan Balancing is able to help. Industry best equipment and 45 years of high performance boring experience gets you a perfect job, every time.
