Desincrustador de agulhas pneumático ks tools 515.3070, desincrustador de agulhas pneumático, máx. 6,3 bar, ligação 1/4 polegadas PT

The Air Needle Scaler ks tools 515.3070 is a pneumatic tool designed for surface preparation and aggressive removal of rust, scale, paint and weld slag. It delivers rapid percussive action through a set of replaceable needles, concentrating impact energy to break and lift adhered material from metal surfaces. The tool connects to a compressed air supply with a 1/4" PT inlet and is rated for operation at pressures up to 6.3 bar, making it suitable for industrial and restoration environments where controlled impact and durability are required.

Advantages

This pneumatic needle scaler provides focused impact force for efficient material removal while limiting damage to underlying metal when used correctly. The replaceable needle set allows easy maintenance and adaptability to different surface conditions. The tool's air-powered operation ensures continuous performance under sustained use and avoids overheating typical of some electric alternatives. Its 1/4" PT air connection and compatibility with up to 6.3 bar input pressure offer straightforward integration with common workshop compressors.

Suitable for

• Removing rust and scale from structural steel and metal components
• Stripping old paint and coatings prior to repainting or surface treatment
• Cleaning weld seams and removing slag after welding operations
• Surface preparation in restoration, shipbuilding, and heavy fabrication

Key specifications

• Operation type: pneumatic needle scaler
• Maximum operating pressure: up to 6.3 bar
• Air inlet connection: 1/4" PT
• Impact method: concentrated percussive action via replaceable needles
• Typical applications: rust, scale, paint and weld slag removal

How to use

Connect the tool to a suitable compressed air supply using the specified 1/4" PT connection and set the compressor pressure to a value not exceeding 6.3 bar. Secure the workpiece and wear appropriate personal protective equipment including eye, ear and respiratory protection. Hold the scaler at a slight angle to the surface and apply steady contact while moving the tool across the work area to break up and remove deposits. Replace worn needles with compatible replacement sets as needed and perform routine lubrication of the tool's air motor following the manufacturer's maintenance guidance.

Recommendations

Use the needle scaler with calibrated air pressure and the correct needle type for the material and coating thickness. For delicate surfaces, test on a small area first to avoid excessive substrate damage. Regularly inspect and replace needles to maintain consistent performance and reduce the risk of rebound or clogging.
