Mandrels and mandrel follower springs, illustrated on page 12 need to be selected to suit the fastener type and size as well as the size
of the hole in the application. Use of the wrong mandrel could increase the risk of breakage and the wear of the mandrel head.
Feeding problems could occur if the wrong mandrel follower spring is used.
While a small amount of wear and marking will naturally occur through normal and correct use of mandrels, they
must be regularly examined for excessive wear and marking, with particular attention to the head diameter, the
tail jaw gripping area of the shank or heavy pitting of the shank and any mandrel distortion. Mandrels which fail
during use could forcibly exit the tool. It is the customer's responsibility to ensure that mandrels are replaced
before any excessive levels of wear and always before the maximum recommended number of placings. Contact
your Avdel representative who will let you know what that figure is by measuring the broach load of your
application with our calibrated measuring tool. These tools can also be purchased under part number 07900-
