IDEAL-TEK 277CFR.SA.1.ITU Plastic Repl CF Tip Tweezers 277CFR.SA, SS Anti-Mag, OAL 120mm-4.72in,(#A277CF tips)
IDEAL-TEK 277CFR.SA.1.ITU Plastic Repl CF Tip Tweezers 277CFR.SA, SS Anti-Mag, OAL 120mm-4.72in,(#A277CF tips)
IDEAL-TEK 277CFR.SA.1.ITU replaceable-tip tweezers combine fine curved A277CF carbon-fiber-reinforced plastic tips with a compact 120mm anti-magnetic stainless steel body. Designed to hold small components firmly, the curved geometry improves visibility and handling ergonomics. The ESD-safe, non-scratching contact material suits sensitive-component handling where a 55° curved approach is preferred.
Best Uses / Applications
- Small-component positioning in ESD-controlled electronics assembly and rework.
- Precision handling where curved access helps maintain a clear view of the working area.
- Handling sensitive micro-mechanical parts where plastic contact is preferred over metal.
- Laboratory handling of glass and ceramic substrates where non-scratching contact is important.
Key Features
- Style 277 fine, curved tips with a manufacturer-listed 55° bend.
- A277CF replacement-tip reference for renewing the working ends.
- CF material: PA66 polyamide reinforced with 30% carbon fiber by weight.
- ESD-safe, low-friction plastic tips with wear and abrasion resistance.
- Sandblasted SA anti-magnetic, anti-acid stainless steel body.
- Conventional squeeze-to-close action, not reverse action.
- Swiss-made tool; manufacturer lists RoHS compliance.

CF temperature and electrical figures describe the material under the manufacturer's test conditions, not guaranteed performance of every assembled tool or process. Heat-deflection temperature is not a continuous working-temperature rating. Use this tool within your established ESD-control procedures.
Selection Comparison
| Model | Geometry and size | Material / ESD distinction |
|---|---|---|
| 277CFR.SA.1 | Fine curved tips, 55° bend, 120mm overall length | CF plastic tips; manufacturer lists ESD safe |
| 259CFR.SA.1 | Straight, fine, pointed, strong tips; 130mm overall length | CF plastic tips; manufacturer lists ESD safe |
| 7MZ.SA.0 | Fine curved tips, 50° bend, 135mm overall length | MZ ceramic tips; manufacturer lists not ESD safe |
Choose the approach angle, tip material and component contact profile together. A similar curved shape does not make the ceramic and CF versions interchangeable for ESD or thermal requirements.
Care and Material Compatibility
Inspect tip alignment and contact surfaces before use. Avoid excessive gripping force, bending and prying. CF offers good resistance to oils, grease, fuels and non-polar solvents, but the manufacturer states it is not resistant to strong acids, alkalis, hot water or steam. Do not assume steam sterilization or an unverified cleaning chemical is suitable. The body's anti-acid designation does not override the plastic tips' limitations.
Frequently Asked Questions
Is this a complete tool or replacement tips only?
277CFR.SA.1.ITU is this complete tweezer listing. A277CF is the manufacturer's replacement-tip reference, not the SKU for the complete tool.
Are these tweezers ESD safe?
Yes. Ideal-tek identifies this model as ESD safe and describes its carbon-fiber-reinforced plastic tips as suitable for sensitive-component handling. Follow your site's ESD-control procedures.
What is the curve angle?
The manufacturer lists a 55° bend. The curved geometry is intended to improve visibility and ergonomics when holding small components.
How large are these tweezers?
Overall length is 120mm, product width is 20mm and height is 18mm. The working tips are specified at 0.70mm wide and 0.80mm thick, with a 16.50mm tip length.
What does carbon-fiber tip material mean?
The CF tips are PA66 polyamide reinforced with 30% carbon fiber by weight. They are not solid carbon fiber and are not ceramic.
Can the tips be used directly against a soldering iron?
Do not assume hot-iron contact is suitable. The CF sheet lists 130°C continuous use and 190°C short-time exposure without specifying the short-time duration. These are material values, not soldering-tip ratings.
Can I steam-clean or autoclave the tips?
The CF sheet states the material is not resistant to hot water or steam. Do not assume steam cleaning or autoclaving is suitable.
Are these reverse-action tweezers?
No. They use conventional squeeze-to-close action. The manufacturer lists a 10mm tip opening gap.
