Countersinking is a popular and inexpensive way to improve both the aesthetics and longevity of your assembled sheet metal parts. The process itself involves drilling conical holes that allow your hardware to embed and lay flush with the outside surface.

Our online DFM checker will automatically detect coutersunk features in your part model and program those holes into the production file. This technology is completely unique to OSH Cut, giving engineers and organizations a serious leg up when it comes to project efficiency.
Most competitors only offer countersinking for aluminum, but with OSH Cut you can add these features to regular steels, stainless steels, and of course aluminum. Our current tooling provides you with 82-degree holes (Imperial) or 90-degree holes (Metric). Typically, as long as the metal is 18-gauge or thicker, the integrity of the hole / depth stop should remain intact. Our range of hole sizes are quite compatible with the different hardware options offered by popular vendors.
Since countersinking is a sub-surface feature, the deburring process may or may not reach all the minute edges or blemishes within the hole. If your part is being bent and/or powder coated, know that holes place near bend die lines can become deformed and hardware may fit tighter-than-expected fitting if there's the added layer of paint.
