Trepanning 21" Diameter Hole in Aluminum

We are trepanning a 21" ID (inside diameter) in this piece of 25" OD x 61" long piece of 6061 aluminum. This process also retrieves a core approx. 19.5" solid round. At Trepanning Specialties we can gundrill, BTA and trepan from .125" to 21" ID's in all kinds of material. (steel, aluminum, titanium, stainless, high-temp, even plastics) This is just one example of our deep hole drilling capabilities.
