Copper Precision Drilling

Copper precision drilling focuses on producing accurate through-holes, blind holes, threaded holes, and complex hole patterns in copper components. Using CNC drilling, reaming, and boring processes, we control hole position, diameter, and depth while minimizing burrs and deformation. Ideal for copper busbars, cooling plates, electrical terminals, and conductive components. Hole diameter tolerance can reach ±0.01 mm, depending on part specifications.
