Knipex 46 11 A2 SBA pliers, external circlips 19-60 mm, tip 0.071 in, 0°

Knipex 46 11 A2 SBA external circlip pliers

The Knipex 46 11 A2 SBA pliers are designed for fitting and removing external circlips on shafts ranging from 19 mm to 60 mm. The straight 0° tips measure 0.071 in diameter and feature a nonslip surface for secure engagement. Chrome vanadium electric steel construction with an atramentized phosphate finish provides corrosion resistance. Black plastic cushion grips offer comfort during repetitive use.

Practical limits of the 0° straight tip design

The fixed 0° tip angle allows direct axial access to circlip holes but cannot reach around obstructions or into angled bores. The 0.071 in tip diameter restricts use to circlips with matching hole sizes; larger or smaller holes require different tips. Spring-loaded handles return the jaws automatically, yet the maximum shaft capacity of 60 mm sets a hard upper limit for larger retaining rings. Non-replaceable tips mean the entire tool must be replaced once tip wear affects grip reliability.

Installation ease and common issues

The pliers operate like standard hand tools: squeeze the handles to open the tips, position them in the circlip holes, then release to grip the ring. The spring return simplifies repeated cycles, and cushion grips reduce hand fatigue. Common problems include tip deformation when excessive force is applied to stuck circlips, and the fixed tip diameter prevents adaptation to non-standard hole sizes. The tool is not tether-ready, so drop protection must be added separately if required.
