I recommend sanding with Kirjes flexible shaft since you can clearly see your progress whilst the sander smoothly follows the contours of your work piece. The flex shaft’s high quality, vibration free design is optimally matched to the mandrels on each sander which makes them the ideal combination.  With a maximum reach of 1300mm the flexible shaft, connected to the easily movable Sanding and Polishing Motor will allow you tremendous flexibility and maneuverability in most work positions. The shaft is intended for low-speed use, around 3.000rpm, mainly for sanding and polishing. This quality Swedish Flex shaft has 2 encapsulated ball bearings in the hand piece and one in the drive end for continuous work and is extremely flexible.  The shaft is rated up to 8,000 rpm with a key chuck from 1.5 - 10 mm.

In the package you get:

• flexible shaft with handle (3x closed ball bearings)
• larger key chuck for shafts from 1.5 - 10mm
• one smaller chuck up to 8mm shaft diameter
