Internal Retaining Ring Plier .049 Tip
The Knipex 44 11 J1 SBA is a fixed-tip internal circlip plier designed for bore diameters from 1/2 in to 1 in. It suits mechanics and technicians who need precise ring removal in tight housings. Chrome vanadium electric steel construction provides durability for repeated professional use. The black plastic-dipped handles offer a secure, non-slip grip during operation.
Installation and Common Issues
The fixed 0-degree tips require direct axial alignment with the ring holes to engage cleanly. Misalignment often bends the .046 in diameter tips or slips the ring, damaging the groove. No spring return means the user must manually open the jaws after each compression, which slows repetitive work. The plastic-dipped handles are not insulated for electrical work.
Compatibility Check
Verify the retaining rings match the 1/2 in to 1 in bore range and accept a .046 in tip diameter before ordering. Confirm the application does not require angled tips or a spring-assisted return for faster cycling. Ensure the 5 3/4 in overall length fits the available access space in your assembly. This tool conforms to DIN 5256 C standard for dimensions.

Questions about this item
How can I verify the 0° fixed tips are seated correctly in a 1/2 in bore after setup?
The .046 in tip diameter should engage the internal retaining ring grooves without play when the handles are squeezed; if the ring releases cleanly and re-seats on the next compression, the plier is working as intended.
What comes in the package and is a spring-return mechanism included?
The box contains one pair of internal retaining-ring pliers with plastic-dipped handles; no spring return is fitted, so the handles stay open until you close them.
Should I choose the J1 model with .049 in tips or a different tip size for bores between 1/2 in and 1 in?
The J1 SBA is specified for .046 in tip diameter and 0° fixed tips, making it the correct version for standard internal rings in the 1/2 in to 1 in bore range.
