Replaceable Insert Forms Formes des plaquettes de coupe Form numbers make searching easier Les numéros associés aux formesfacilitent la recherche In addition to established ISO inserts, the Wohlhaupter range contains many replaceable inserts which cannot be represented in the ISO key. So in the late ’70s, Wohlhaupter decided to introduce a formnumber to identify the replaceable inserts – before the corresponding DIN or ISOstandards even took effect. This proved tobe a great success and will continue inspite of the introduction of a system for order numbers (see page 28). Le programme Wohlhaupter...
