Knipex 5-1/4" Precision Electronics Pliers – Flat Smooth Jaws, 34-12-130

Handle delicate components with precision and control using Knipex precision electronics gripping pliers. Designed for fine assembly work in electronics, precision mechanics, and other detailed applications, these compact pliers feature flat, wide jaws with smooth gripping surfaces for securely holding and positioning small parts.

The smooth jaws are especially useful when working with delicate components and materials where serrated gripping surfaces could leave unwanted marks. Carefully rounded edges provide additional protection when gripping, bending, and manipulating small parts.

A precision bolted joint ensures smooth, consistent movement throughout the opening range, while the low-friction double spring gently opens the jaws after each squeeze. Ergonomically designed multi-component handles provide a comfortable, secure grip during repetitive work.

Manufactured in Germany from chrome vanadium ball-bearing steel, these lightweight pliers combine durability, precision, and comfortable handling for demanding bench applications.

Smooth Jaws for Delicate Components

The flat, smooth gripping surfaces are designed for applications where secure handling is important but aggressive serrated jaws are unnecessary.

They provide even contact when gripping small parts, helping reduce the risk of unwanted surface marks during assembly, adjustment, and repair.

This makes them especially useful for precision electronics, jewelry work, and other applications involving delicate components.

Precision Bolted Joint for Consistent Movement

The carefully manufactured bolted joint provides accurate alignment and smooth, low-friction movement throughout the pliers' opening range.

Unlike conventional joints that may develop noticeable play, this precision design helps maintain controlled movement when positioning and manipulating small components.

Comfortable Handling for Repetitive Work

The low-friction double spring automatically opens the jaws after each squeeze, reducing the effort required during repeated gripping operations.

Combined with ergonomic multi-component handles and lightweight construction, the design provides comfortable handling during detailed assembly and repair tasks.
