Chicago Pneumatic 8941071200 Air Inline Needle Scaler

Product Description

The CHICAGO PNEUMATIC 8941071200 is an air-powered inline needle scaler designed for surface preparation work including rust removal, paint stripping, weld scale cleaning, and concrete surface profiling. Operating at 4,800 beats per minute with a 1.18-inch stroke, this tool delivers consistent impact energy through its needle bundle. It accepts a 3/8-inch air inlet and requires 15 SCFM at 90 psi to operate at rated performance. The inline body style positions the needle bundle in line with the handle, making it well-suited for flat surfaces and confined areas. Needle diameter is 3mm with a 19mm needle length. Licensed tradespeople in fabrication, shipyard, structural steel, and industrial maintenance environments are the primary users.

This needle scaler is used in industrial and commercial applications where surface preparation must meet coating or weld inspection standards. Typical install scenarios include pre-weld joint cleaning, post-weld scale removal, rust remediation on structural steel, and surface profiling ahead of protective coatings. The inline configuration suits horizontal and overhead flat-surface work. It connects to a standard shop air system via a 3/8-inch NPT inlet. At 6.2 pounds, the tool is manageable for extended use at a workbench or on a fabrication floor.

Key Features

• 3mm needle diameter with 19mm needle length
• 3/8-inch air inlet compatible with standard shop air fittings
• Operates at 90 psi and 15 SCFM for consistent pneumatic performance
• Inline body style suited for flat surfaces and tight access areas

Compatibility

Designed as an OEM-style replacement or direct-use inline needle scaler for industrial pneumatic surface preparation applications requiring a 3/8-inch inlet tool at 90 psi operating pressure.

Installation Notes

Installation and operation of this tool should be performed by qualified tradespeople familiar with pneumatic tool safety procedures. Before connecting or disconnecting the tool, shut off the air supply and bleed the line to relieve pressure. Verify the shop air system can sustain 15 SCFM at 90 psi at the tool inlet to avoid performance loss. Always wear appropriate PPE including eye protection and gloves when operating needle scalers, and ensure needle retainers are in place before connecting to air supply.
