(2) Easy-to-operate variable speed dial on the handle (Model M 8V2)
A dial for the rotation speed control is provided on the handle (Fig. 2).
Thanks to this unique structure, the operator can change the rotation
speed without releasing the hand from the handle. So when cutting
workpieces, the operator can adjust the rotation speed finely while
checking the cutting condition.

(1) Powerful motor to rout smoothly through hardwoods
A powerful and fast motor was developed for the Models M 8V2 and
M 8SA2. The fan is made of aluminum and it has a ring-shaped
junction at the outer circumference as shown in Fig. 1.
Thanks to the unique structure, the moment of inertia of the armature
that is an element for increasing the cutting efficiency is increased
and the class-top cutting speed is obtained.
(3) Improved clutch
The Models M 8V2 and M 8SA2 are provided with the collet chuck that clutches the bit into the armature shaft
for improved clutch.
