Circlip Pliers
Pliers and Cutting Tools
Circlip pliers fit and remove retaining rings to DIN 471 on shafts and to DIN 472 in bores. The plier design follows DIN 5254; models differ by ring type (J for internal rings, A for external rings), size group 0 to 6 and straight or angled tips. Overall lengths run from 140 to 580 mm, and convertible versions cover internal and external rings with one tool. Spare tips as well as sets of four or eight pliers complete the programme. The category holds 163 items, mainly from Knipex and Wiha.
