The function of the guide bushing is to direct the gundrill into the material during penetration. The diameter of the guide bushing should be within 20 microns larger than the diameter of the drill. Dedicated gundrill machines are equipped with a guide bushing system. Sealing Disk Supplied with a single sealing disk or a protection sheet. Indicate the dimensions needed for your requirements.
