Removal of Rivets
Remove rivets from the side of the rivet, which is more accessible.
Drill out the rivet head and drive out the shank.
NOTE
Center-dot heads of solid rivets, which shall be drilled off.
Use a drill bit of 0.5 mm (0.025 in) smaller diameter than the rivet
shank and drill up to the depth of 2/3 of the total depth riveted parts.
Remove the drilled heads with a sharp cuter. Drive out the shank with
the soft material mandrel of 0.1 mm (0.004 in) smaller diameter than
rivet shank. The rivets, which cannot be driven out should be drilled
out full depth. When removing rivets be careful that chips and rivets
do not fall down to areas were sensitive mechanisms are located, e.g.
guides, control bearings etc.
