LINDSTROM® RX Series Plier #RX7891

Position sensitive miniature components, shape precious metal wire with positive mechanical traction, and eliminate repetitive bench strain during high-precision assembly. Developed in Sweden and manufactured to premier aerospace and microelectronics standards, the LINDSTROM® RX Series Snipe Nose Pliers (#RX7891) represent the pinnacle of ergonomic hand tool engineering.

Engineered with fine, 32 mm elongated chain nose jaws (Snipe Nose) featuring precision cross-serrated inner gripping faces, the RX7891 prevents wire slippage and delivers firm mechanical grip when bending hard-temper alloys, forming jump rings, or routing electronic leads. The forged Swedish high-carbon steel chassis is tough-hardened to 55–58 HRC and connected by Lindstrom’s signature precision screw joint that minimizes friction and preserves exact tip alignment throughout the tool's life. Featuring the patented Biospring® adjustable tension system and dual-component ESD-Safe ERGO™ handles with Micro-Touch™ geometry, the RX7891 allows artisans to rotate the tool smoothly between thumb and index finger with minimal hand effort.

Why Choose LINDSTROM® RX7891 Snipe Nose Pliers

• Precision Serrated Inner Jaws: Machined with fine horizontal serrations across the inner jaw faces to provide slip-free holding power when pulling stiff wire or setting small components.

• Patented Adjustable Biospring® System: Limits and balances closing tension across the entire operating cycle. The dual-leaf spring adjusts to three distinct tension positions or detaches completely to suit individual hand preferences.

• Micro-Touch™ Ergonomic Handle Profile: Specially contoured handle wings allow effortless rotation and micro-adjustments between the thumb and forefinger for delicate positioning under magnification.

• Two-Component ESD-Safe ERGO™ Grips: Conductive thermoplastic elastomer bonded over a rigid polypropylene core dissipates electrostatic charges while providing a tactile, non-slip grip resistant to bench oils.

• Ultra-Low Friction Precision Screw Joint: Machined threaded pivot screw maintains exact jaw alignment under lateral twisting forces while operating with buttery-smooth mechanical glide.

• Induction Hardened Alloy Steel (55–58 HRC): High-grade alloy steel construction delivers long-lasting structural rigidity, edge retention, and wear resistance.
