Stripper RS stock no. 541-573.
A nibbling attachment/dieholder which in conjunction with elliptical
punch and die, can be used to cut internal circles between 30mm and
140mm dia.
Punch, die, attachment/dieholder setting procedure.
1. Raise the ram to the 'up' position.
2. Fit the punch into the ram, locating the grub screw in the undercut.
3. Set the attachment/dieholder, RS stock no. 607-617 down onto the
press base and retain with the four screws provided. Do not lock at
this point.
4. Lower the punch into the die, orientating their position so that the
ellipse shape will cut the closest approximation to a circle.
5. With the punch in the die, lock the punch in the ram, the die in the
attachment/dieholder, then secure the dieholder firmly to the press
frame.
6. Raise and lower the punch in the die several times to ensure that
they align and do not foul each other. Make sure all screws are
tightened firmly, but not overtightened.
7. Set the adjustable stop (Figure 1) to limit ram throw. It is
recommended that the punch enters the die
Radius nibbling and circle cutting with stripping action
8. The attachment has a sliding bar and pin which can be positioned
and locked in the attachment/dieholder so that the pin is set at a
distance r between the pin centre and the back edge of the elliptical
die shape,(Figure 6). Where 2r is the diameter of the completed
hole, (Figure 7).
9. Note:The sliding bar has three tapped holes, which will accept the
locking screw, (Figure 6). By using the appropriate tapped hole, the
pin can be locked in any position with r ranging from 15mm to
70mm.
10. Drill or punch a 3 mm dia. hole in the work-piece, and locate the
pin through the hole, (Figure 7) so that it acts as a centre fulcrum
about which the workpiece can revolve.
Note: Turning may be limited by the throat depth of the press.
11. Fit stripper, RS stock no. 541-573, (Figure 7) for repetitive
punching. Set the stripper position so that the hole in the stripper
allows full closure of the punch and die but with sufficient
clearance for material to feed between the die and stripper.
12. Commence nibbling by pulling the press handle down firmly to
pierce the material, then raising the punch to give stripping action.
13. Turn the workpiece on the pin fulcrum and continue to nibble until
a hole 2r diameter is cut out.
14. As the elliptical punch produces a ripple effect along the cutting
edge (see inset Figure 7), smooth down with a file if necessary.
15 Accurate and repeatable 5 hole punching, (Figure 8), can be
achieved by using circular hole punches.
16. Note: The points of caution and information given under points '15
'to '17' and '19'.
Cutting and slotting
Accessory required
Cutting tool RS stock no. 541-400.
Used in conjunction with press RS stock no. 541-309, this guillotine
style tool has a 3.18mm (

The blade cuts a 63.5mm length by
Will give a cutting and slotting action in sheet materials without material
distortion. Features optimum usage with minimum wastage. Can also
be used for trimming corners.
Setting procedure
1. Raise the ram to the 'up' position.
2. Set the die down on the press base and retain with the four screws
provided. Do not lock at this point.
3. Fit the blade into the ram (Figure 9) ensuring that the locking screw
in the ram holds the blade spigot at the undercut. Do not lock at this
point.
4. Bring the ram slowly down and locate the complete length of the
blade into the die slot .

5. Lock the blade in the ram and then the die down to the base.
6. Raise the ram up and down several times to ensure free alignment
of blade and slot.
7. Set the adjustable stop (Figure 1) to limit ram throw. It is
recommended that the stop is set so that the blade enters the slot
along its full length during operation but does not 'bottom' onto the
die body.
Operating procedure
8. Lower the blade so that the toe just enters the slot, then feed the
workpiece (flat against the die face) up to the position, (Figure 10a).
9. Holding the workpiece steady, pull the handle down firmly following
the line of cut with the blade edge to the position (Figure 10b).
10. Raise the blade, feeding the workpiece along, keeping the toe in
the slot, (Figure 10c).
11. With the workpiece flat on the die face repeat as in 9 and 10 until
the line of cut is complete.
The tool may also be used to crop edges and corners.
Points of caution and information
12. Use materials up to the max. thicknesses as specified.
13. To prevent material build up ensure that the slot does not get
jammed with cut-outs.
14. Always ensure that the tool is free of waste material and is lightly
oiled before storage.
15. Protect the tool surfaces and edges from damage by storing in the
packaging supplied.
16. Do not use the toe for punching or cutting.
Corner notching
Accessory required
Notching tool RS stock no. 541-416.
A corner notching tool used in conjunction with press RS stock no. 541-
309 having a 90° Corner punch with 53mm length cutting edges
(tapered for easier cutting) and a compatible die base with adjustable
corner stops to set corner lengths independently between 0 and 65mm.
Setting instructions
1. Raise the ram to the 'up' position.
2. Set the die down onto the base (Figure 11).
Retain with the four screws provided but do not lock at this point.
3. Place the punch in the die.
4. Slowly lower the ram, locating the hole in the ram onto the punch
spigot.
5. Using the adjustable stop (Figure 1) to hold the ram in position, set
the 90° corner of the punch squarely in the 'V' of the die, locking the
punch in the ram at the spigot undercut.
6. Raise and lower the punch in the die so that there is a clearance
between cutting edges.
7. Lower the punch into the die and lock the die base.
8. Raise and lower the punch again to ensure free movement in the
die.
9. Set the adjustable stop (Figure 1) to limit ram throw.
Adjustable corner stops
10. Two stops (Figure 11) have slots for adjusting their position with
respect to the die cutting edges.
11. Set distance 'd', (Figure 11) to give a repeatable corner notch of
that dimension. Lock the stop.
12. Locking screws can be used in two positions, (Figure 12a) to give
set corner dimensions infinitely adjustable up to 65mm.
13. Note that the punch sides are 53mm length, being the maximum
corner which can be cut at one stroke.
14. The stops may be removed completely for larger notching.
Operating procedure
15. It is important to note that the workpiece reference edges should be
at 90° so that true right angle corners can be cut by the tool.
16. Set the stops to the required distance.
17. Offer the workpiece up against the stops and flat against the die
face, (Figure 12a).
18. Holding the workpiece, pull the handle firmly down in one stroke, to
punch a corner notch, (Figure 12b).
19. For corners in excess of 53mm per side use the punch to nibble
away smaller corner pieces until the full corner has been cut.
