Tweezers Knipex 92 81 04 stainless steel pointed tip 130 mm, ESD-safe

Knipex 92 81 04 is a 130 mm stainless steel tweezer with pointed interchangeable tips designed for precise handling of small and delicate parts. The tool combines a premium stainless steel body with carbon-fibre reinforced plastic tips that provide surface protection, controlled dissipation of electrostatic potential and high resistance to corrosion and heat.

Advantages

The polished, handcrafted stainless steel body offers a matt, scratch-free and non-reflective surface with high temperature and chemical resistance. Interchangeable tips made from 30% carbon-fibre reinforced plastic are electrically and thermally conductive, abrasion-resistant and remain stable at temperatures up to 130 °C (short-term up to 190 °C). Tips feature surface resistance in a controlled range to reduce static differences between operator and components while maintaining the same accuracy and stability as conventional tweezers through a three-point, zero-backlash attachment.

Suitable for

• Electronics assembly and repair (handling sensitive electronic components)
• Precision engineering and micro-mechanical work
• Watchmaking and jewellery work
• Laboratory handling of glass, ceramic and small parts

When it may not be suitable

This tweezer is designed for precision and ESD-sensitive tasks; it may not be the best choice for heavy-duty gripping, cutting or prying where stronger, non-precision pliers are required. For applications requiring continuous exposure to very high temperatures above the specified short-term limit, a tool made entirely of high-temperature alloy would be more appropriate.

Key specifications

• Length: 130 mm
• Body material: premium stainless steel, handcrafted, matt finish
• Tip material: 30% carbon-fibre reinforced plastic (interchangeable)
• Tip surface resistance: approximately 10^2–10^3 ohms (controlled dissipation)
• Tip temperature stability: permanently up to 130 °C, short-term up to 190 °C
• Chemical resistance: good resistance to most oils, lubricants, fuels and nonpolar solvents
• Design: pointed tips; three-point zero-backlash connection for stable attachment

How to use

Hold the tweezers by the stainless steel body and use the pointed tips to precisely pick, place or adjust small parts. For ESD-sensitive components, ensure proper grounding procedures are followed; the tips provide controlled surface resistance but do not replace grounding straps or ESD workbench controls. Interchange tips as needed by loosening the attachment screw, replacing the tip with a compatible shape, and securing it with the three-point connection to restore zero-backlash accuracy.

What to consider before purchase

• Confirm the 130 mm length and pointed tip shape meet your access and grip requirements
• Ensure tip surface resistance range (approx. 10^2–10^3 Ω) is suitable for your ESD protocols
• Consider whether interchangeable tip availability covers the shapes you need for future tasks
• For heavy mechanical work or continuous exposure above 190 °C, choose a different tool

Usage recommendations

Store tweezers in a clean, dry place and avoid contact of the plastic tips with strong oxidisers or polar solvents. Use appropriate ESD controls (grounding wrist strap, ESD bench) when handling sensitive electronics and replace tips if worn to maintain precision and controlled dissipation.
