Minor Diameter Drill Chuck

Despite the genuine products, the vibration of the ultra fine drill attached with the collet chuck has an accuracy of 0.05 mm - 0.1 mm, but if it is made into a small diameter drill chuck, the deflection of the ultra fine drill is 0.1 mm - 0.5 mm or more. If there is a touch of 0.5 mm or more with a very fine drill with a blade diameter of 0.5 mm, it will break with one shot whether it is wood or nonferrous metal. Even with a drill with a blade diameter of 3 mm, if there is a touch of 0.5 mm or more, a hole of 3.25 mm or more is opened in the processing hole. Clearly it does not become usable. Small diameter drill chuck (Proxon compatible item · equivalent) attached to each company mini router other than Proxon also has the same swing as Proxon.

Small diameter drill chuck standard standard mini router can not be used properly.

Since Proxon is genuine, there is nothing like a problem in using it. Since the corresponding shaft diameter is stepless, bits from other manufacturers become usable, which makes it considerably convenient. Chuck accuracy was not particularly problematic.
