Twister tools are supplied in sets according to the working angle. Available in sets of 30 st. / 37.5 st. / 45 st.
The tool is already factory ed with cu ng inserts Order No. 28015.
Before use, it is necessary to adjust the posi on of the slice so that the cu ng edge of the slice is safely inthe area of the wall of the pipe to be machined. In other words, the radius of the working edge posi on
rela ve to the axis of the Twister tool must be adjusted according to the radius of the pipe being machined.
Use one of the three moun ng holes in each arm of the Twister tool to set the correct slice posi on.

Now you have to mount the prepared tool on the B15 Electra, B15 AIR or alterna vely on the B10 Electra.
Screw the Twister tool onto the spindle of the machine and ghten sensi vely with the supplied pipewrench.

tiBefore using the tool itself, it is s ll necessary to t the tool with the correct guide mandrel. The main taskof the guide mandrel is to stabilize the tool inside during machining. For this reason, always select thediameter of the guide mandrel closest to the smaller, inner diameter of the pipe to be machined. Guide
mandrels are available with outer diameters of 19mm (0.74"), 24mm (0.94"), 32mm (1.25"), 38mm (1.49"),49mm (1.92").
Fit a suitable mandrel into the threaded hole located in the axis of the tool. Tighten the guide mandrel
properly with the included inbus wrench.
The manufacturer, N.KO Machines, also o ers the produc on of custom-made mandrels, with working
diameters made exactly according to the speci c pipe to be machined. Ask your supplier.

Safety cover
The Twister must only be used with the safety cover. The safety cover is not included in the Twister kit. It
must be purchased separately. The safety cover can be purchased under order number 27409 from yoursupplier. The safety cover protects the operator from ying splinters.
The safety cover is installed on the backing plate of the B15 ELECTRA, B15 AIR and B10 Electra. Wheninstalling the cover, open it slightly and place it on the backing plate as shown in the picture below. The gap
in the cover must be in the down posi on. This is the point through which the chips fall out. Finally, we
recommend securing the cover with a screw (screw not included with the cover).

Machining
The tube to be machined must be properly clamped, for example in a vice, so that machining is safe. Thedrive must be equipped with a side handle. Hold the drive with both hands! Place the machine with theTwister tool on the pipe so that the guide mandrel is par ally inserted into the machined pipe, but thecu ng slices are not yet touching the edge of the machined pipe. Now switch on the machine and wait
un l it reaches full speed. Then start machining by pushing the machine with the Twister tool towards theedge of the pipe to be machined.

ATTENTION! The axis of the Twister tool must be parallel to the axis of the pipe to be machined. Otherwise,
the bevel will be uneven and the tool may jam on the pipe. This can be dangerous for the machine or forthe operator. Keep the Twister tool pressed against the pipe un l the desired machining is achieved.
Then remove the machine with the Twister tool from the pipe to be machined and switch o the machine.
