Pneumatic Jet Chisel JEX-24 – High-Efficiency Descaling Tool for Marine Applications

The Pneumatic Jet Chisel JEX-24, also known as a pneumatic needle scaler, is designed for heavy-duty surface preparation in shipbuilding and repair. It excels at removing weld slag, spatter, rust, and old coatings from irregular surfaces, thanks to its self-adapting needle bundle that conforms to contours. With a maximum working pressure of 0.6 MPa (87 psi) and an impact frequency of 4000 blows per minute, this tool delivers fast, efficient cleaning without damaging the base material.

Weighing only 2.7 kg (6.0 lbs), the JEX-24 offers an excellent balance of portability and power, making it ideal for extended use in confined spaces. It comes standard with 3 mm x 180 mm needles (23 needles) and includes a needle holder that can also accommodate 2 mm x 180 mm needles (53 needles) when swapped. All spare parts, including descaling needles and needle holders, are readily available. CE certified and compliant with international safety standards.
