Ingersoll Rand 172LNA1 Inline Needle Scaler is designed for surface preparation, rust removal, and cleaning applications where a compact pneumatic scaling tool is required. Featuring 5,500 blows per minute, a 0.56" stroke length, and a 0.88" bore, this needle scaler delivers rapid impact action for removing corrosion, scale, coatings, and other surface contaminants from metal surfaces.
The inline design provides a straight operating configuration for controlled surface preparation work, while the needle-style cutters conform to irregular surfaces and help clean areas around welds, edges, and complex shapes. The 5,500 BPM impact rate provides repeated striking action for maintenance and construction applications where pneumatic surface cleaning performance is required.

FAQs:
- Q: What is the Ingersoll Rand 172LNA1 used for?
A: The 172LNA1 is an inline needle scaler designed for removing rust, scale, coatings, and other surface contaminants from metal surfaces. - Q: What is the impact rate of the 172LNA1?
A: The manufacturer specification lists the tool at 5,500 blows per minute. - Q: What does the stroke length indicate on a needle scaler?
A: Stroke length refers to the distance the needles travel during each impact cycle. The 172LNA1 has a listed stroke length of 0.56". - Q: What type of surfaces can a needle scaler clean?
A: Needle scalers are commonly used on metal surfaces to remove rust, scale, coatings, and similar buildup before maintenance or finishing work. - Q: Why use a pneumatic needle scaler instead of manual surface cleaning methods?
A: A pneumatic needle scaler uses repeated impact action to help speed up surface preparation compared with manual scraping or chipping methods.
