General Info

Acromatic Deep Hole Drilling is a precision deep hole drilling service based in Troy, Michigan since 1974. We specialize in gun drilling on steel bars and materials like copper, bronze, plastic, and aluminum. In order to maintain the straightness of the holes while keeping the tolerance and surface finish intact, you need to have the proper drilling equipment and expertise, and that's where we come in. We also drill flat stock bars and can drill off-center for more complicated fixtures. Give us a call today to discuss your upcoming project and see how we can help!
