Accessory for creating a thread inside and outside a little or medium size wooden object.

Three Ø 16, 25 and 30 mm stems which are mounted on the threading device plate; the stem is then inserted directly into the tool support holder. It is practical but also solid and robust.

Once the chuck has been placed in height, with the help of its specific centering device, the tool rest is adjusted in an orthogonal position and, even during its usage, it can be moved to perform a measurement and a check, without loosing the same position. It is possible to check and increase the depth if necessary.

The leadscrew has a M33x3,5 mm thread for assembling the chuck. Standard equipment allows to create a 2,5 mm pitch metric thread. For the creation of a 3,5 mm pitch metric thread, it is necessary to replace the supplied leadscrew with an optional one, whose pitch is 3,5mm (art. 4078). The maximum thread length is 50mm.

It is also possible to create a 2,5mm trapezoidal threads, which are more resistant and perfect for fresh/green wood. For this operation, a specific cutter (art.4079) is needed.

It is recommended to fasten the cutter on the headstock by using the collet chuck holder ER25 (Art. 4036) and the 14mm collets ER25 (Art.3078). Otherwise, it is also possible to use 25 mm jaws of good quality.
