Chicago Pneumatic 8941071500 Pneumatic Scaling Hammer

Product Description

The CHICAGO PNEUMATIC 8941071500 is a pneumatic scaling hammer designed for removing rust, scale, weld slag, and surface buildup from metal structures, welds, and fabricated assemblies. Powered by compressed air at 90 psi working pressure, it delivers 2,300 blows per minute with a 3.5-inch stroke length, providing aggressive material removal in a compact handheld form. Air consumption runs at 25 CFM through a 1/4-inch NPT inlet. It is a standard tool for industrial maintenance crews, shipyard workers, structural steel fabricators, and pipefitters who need fast, repeatable descaling performance on the job.

This scaling hammer is suited for industrial and commercial applications where surface preparation is required before coating, welding, or inspection. Typical use cases include descaling pipe welds, cleaning structural steel, removing mill scale from plate, and prepping concrete anchor points. The 1/4-inch NPT air inlet is compatible with standard shop air fittings and hose assemblies. Operators working in confined spaces, shipbuilding, bridge maintenance, and heavy fabrication environments will find the stroke length and blow rate appropriate for production-level descaling tasks.

Key Features

• 2,300 blows per minute for high-rate scale and rust removal
• 3.5-inch stroke length delivers strong impact force per blow
• 25 CFM air consumption at 90 psi working pressure
• 1/4-inch NPT air inlet fits standard shop air connections
• Pneumatic drive eliminates battery dependency in industrial environments
• Weighs 7.9 pounds for a handheld power-to-weight ratio suited to extended use

Compatibility

Designed for use with standard compressed air systems operating at 90 psi. Compatible with 1/4-inch NPT air fittings and hose assemblies typical in industrial and fabrication shop environments.

Installation Notes

Installation and operation should be performed by qualified tradespeople familiar with pneumatic hand tool safety. Before connecting or disconnecting the air supply, depressurize the line and verify the inlet fitting thread type matches the supply hose fitting. Operators should wear appropriate PPE including eye protection, hearing protection, and vibration-dampening gloves during use. Inspect chisels and scaling bits for wear or damage before each use and ensure they are properly seated before connecting air.
