Gun Drilling

Our focus on the micro gun drilling process is integrated with precision Swiss machining. This way we can bore deep holes in tough materials and finish the work piece saving costly secondary set ups. Threaded parts, milled flats, thread whirling, etc

The following chart shows drill size and depth capability

Drill size Depth

.020” (.5mm) 2.00” (50mm)
.030” – .035” (.77mm- .9mm) 2.250” (57mm)
.040” -.078” (1mm-2mm) 3.00” (76mm)

The finish that gun drilling provides is a big benefit for some types of jobs that require a smooth bore. We can control the finish with speeds and feeds and of course how often we sharpen the drills. Depending on the drill size anywhere from a 4 micron to 16 micron finish is possible

When machine finish is not good enough We have the capability to hone any geometric cavity to a sub micron finish.

See our gun drilling video of a .020 (.5mm) x 1.575” depth in A2 steel

We can job out tough parts or engineer a turn key system for your company.
