Purpose-built external circlip plier
The Knipex 46 21 A01 SBA is a fixed-tip external retaining-ring plier forged from chrome vanadium electric steel. Its 0.035-inch tips are bent 90 degrees for access in tight bores and shafts ranging from 1/8 to 3/4 inch. A spring-return mechanism speeds repetitive work, while plastic-dipped handles give a secure grip. The 5-inch overall length keeps the tool compact for confined engine bays or gearbox assemblies.
Upgrade from generic snap-ring pliers
Replace adjustable or straight-tip pliers when the job demands consistent tip alignment and a 90-degree reach. The fixed tips eliminate jaw walk on stubborn circlips, and the DIN 5254 B manufacture ensures dimensional accuracy that loose-jointed tools cannot hold. The jump is worth it when external rings are recessed or surrounded by obstructions that straight tips cannot clear.
For technicians removing external circlips daily
Mechanics, millwrights and assembly technicians who repeatedly service shaft-mounted clips will value the spring return and precise tip geometry. Users needing internal-ring capacity, interchangeable tips or larger shaft coverage should look at other models, as this plier is dedicated to external rings within the stated diameter range only.

Questions about this item
What shaft diameters can the 0.046 in tips on the Knipex 46 21 A01 SBA grip?
The fixed 90° tips are designed for external retaining rings on shafts from 1/8 in to 3/4 in.
How do you install the spring return on these pliers?
The spring return is factory-fitted; no separate installation is required — just open the handles and the spring pushes them apart automatically.
When should the plastic-dipped handles be replaced?
Replace the handles if the black plastic dip cracks, peels or becomes slippery, as this reduces grip and insulation on the Chrome Vanadium Electric Steel frame.
