1 –   Drill a pilot hole in the plate at the desired point, using the ø 11.5 mm spiral bit supplied with 
   

the 

tool. 

2 –   Fully screw the 

TD-11

 draw stud into the ram (16) of the head.

3 –   Thread the die onto the draw stud, pushing it to rest on the head.
4  –   Insert the draw stud into the pilot hole and screw the punch onto the draw stud until its cutting 
      edges are touching the back of the layer of material being punched.

Round holes ø 28.5 to 89 mm  

(Ref. to Fig. 4)

–  Drill a pilot hole in the plate at the desired point, using a ø 20 mm spiral bit; alternatively, it is 
  possible to make the pilot hole with the ø 11.5 mm spiral bit supplied with the tool and widen it 
  with the KIT RD20.5SS.
–  Fully screw the draw stud 

TD-19

 into the ram (16) of the head.

  NOTE: the TD-19 draw stud is threaded 3/4" at both ends, screw the short thread into the ram.

–  Continue as described in points 3 and 4 above. 

Round holes ø 100 and 120 mm  

(Ref. to Fig. 4)

–  Drill a pilot hole in the plate at the desired point, using a ø 29 mm spiral bit; alternatively, it is 
  possible to make the pilot hole with the ø 11.5 mm spiral bit supplied with the tool and widen it 
  with the KIT RD30.5SS.
–  Fully screw the draw stud 

TD-28,5

 (supplied with the Punching Kit) into the ram (7) of the head.

–  Continue as described in points 3 and 4 above.

Square and rectangular holes  

(Ref. to Fig. 4)

–  With a drill make the required pilot hole in the plate at the desired point.
–  Fully screw the draw stud (supplied with the Punching Kit) into ram (16) of the head.
–  Thread the die into the draw stud, pushing it to rest on the head. 
–  Insert the draw stud into the pilot hole then thread the punch onto the draw stud until its cutting 
  edges are touching the back of the layer of material being punched.
–  Fully screw the locking ring onto the draw stud to lock the punch in place.

2.2) Head rotation

(Ref. to Fig. 1)

Two independent joints enable the tool head to turn through 360° and rotate through 180°, allowing 
the operator to work in the most comfortable position.

Warning: do not attempt to turn the head if the hydraulic circuit is pressurised.

2.3) Punching  

(Ref. to Fig. 3)

Before punching:

• 

Check the correct match between die and punch.

• 

Check that the draw stud is completely screwed into the ram.

• 

Check that the punch is completely screwed onto the stud, with its cutting edges touching the 

  back of the layer of material being punched.
•  Keep hands away from the punching zone to avoid serious risk of injury!
