The Tronex P521S and P721S Needle Nose Pliers are precision tools designed for gripping, holding, bending, and positioning small components where extra reach and a secure grip are required. Featuring long, tapered needle nose jaws with serrated tips, these pliers provide enhanced gripping ability for fine wire and small parts while allowing access to confined areas.
The serrated tip design helps prevent slipping when handling components, making these pliers especially useful for electronics assembly, jewelry making, wire work, and precision applications where a stronger grip is needed. The long, thin jaw profile provides excellent access and visibility around delicate assemblies.
The P521S features standard handles for excellent control and maneuverability, while the P721S features longer ergonomic handles that provide additional leverage and reduce hand fatigue during extended use. Both models include Tronex ESD-safe cushion grips and a protective tip cap for safe storage.

Frequently Asked Questions
What is the difference between the P521S and P721S?
The jaws are identical on both models. The P521S features standard handles for excellent control and maneuverability, while the P721S features longer ergonomic handles that provide additional leverage and improved comfort during extended use.
What are serrated needle nose pliers used for?
Serrated needle nose pliers are designed for gripping, holding, and positioning small components where extra traction is needed. The serrated tips help reduce slipping compared to smooth jaw pliers.
How are the P521S/P721S different from the P521/P721 smooth jaw models?
The P521S/P721S feature serrated tips for increased gripping power, while the P521/P721 have smooth jaws designed for applications where minimizing marks on delicate materials is more important.
Will serrated jaws mark jewelry wire?
Yes. Serrated jaws provide a stronger grip but may leave marks on softer metals or finished surfaces. For applications where a mark-free finish is required, smooth jaw pliers may be a better choice.
What are long tip needle nose pliers best used for?
Long tip needle nose pliers are ideal when you need extra reach for gripping, bending, and positioning small components in tight or recessed areas.
Can these pliers cut wire?
No. The P521S and P721S are gripping and forming pliers only. Use a Tronex precision cutter for cutting wire.
Can I use these pliers with memory wire?
No. Memory wire and other hardened materials should not be used because they can damage the precision jaws.
Should I choose these or short-tip needle nose pliers?
If you need access to deeper or harder-to-reach areas, the long tip design of the P521S/P721S is the better choice. If you do not require the additional reach, a shorter tip design may provide increased strength and more control during general gripping tasks.
Are these pliers suitable for electronics work?
Yes. The long tapered jaws and ESD-safe grips make these pliers especially useful for electronics assembly, repair, and precision manufacturing applications.
Note: Serrated Tips
