8.3.1 Cutting bit and double bit keys
1) Prepare the clamps with the required side facing the cutter and tracer point (fig. 38) (fig. 39).
2) Lock the clamps in the horizontal position by means of the pin (L).
3) Place the key to be cut into the left-hand clamp.
Note: leave clearance at least 2 mm between the bit and
clamp.
4) Raise the carriage and place the bit against the cutter (fig. 40).
5) Secure the original key in the right-hand clamp, placing the bit
against the tracer point; this will ens ure that the two k eys are

6) Proceed with cutting (fig. 41); if necessary, activate tilting to flare the cuts (chap.8.1.5, page 22).
7) Raise the carriage with the handle (H) and take the original key into contact with the tracer point to
carry out cutting.
8) Take the carriage back with the handle (H), go on to the next cutting position and continue from point
