Round holes ø 15.5 to 30.5 mm (Ref. to Fig. 4)
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 (see Tab. 2) 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
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!
