The 170mm 90° Tip Internal Circlip Pliers are a specialist hand tool for inserting and removing internal circlips (retaining rings) in confined or angled bores. Their 90° bent tip geometry gives access to circlips seated in blind or recessed grooves where straight pliers cannot reach, making them the primary choice for internal retaining-ring work on shafts, housings and assemblies.

These pliers are manufactured from chrome‑vanadium (Cr‑V) alloy steel which is drop‑forged and heat treated for durability and strength. The working tips are induction hardened to resist wear and retain edge integrity, while the body is finished with a satin chrome plate to improve corrosion resistance. The tool is 170mm overall length, features an internal (pin‑to‑pin) head type with 90° bent tips and a sprung joint for automatic opening. Thread type and drive type are not applicable to this class of pliers.

Designed with the needs of maintenance and assembly professionals in mind, the tool is suitable for applications across automotive workshops, gearbox and transmission repair, hydraulics and pneumatics servicing, electrical motor and pump maintenance, and general engineering and fabrication. It is particularly useful where circlips are located in narrow bores, gearboxes, bearing housings and small machinery assemblies common to aerospace, agricultural machinery and industrial plant maintenance.

Key benefits include enhanced corrosion resistance from the chrome finish and improved tip life from induction hardening, offering good longevity in workshop environments. The Cr‑V construction provides the mechanical strength required to open internal circlips without excessive flex, while the 90° bent tips ensure compatibility with recessed grooves and awkward angles. Ergonomically dipped handles reduce hand fatigue and provide a secure grip for controlled operation.
