The BGS 6230 air needle scaler is a specialized pneumatic tool designed for the removal of rust, coatings, and contaminants from solid metal surfaces. This tool operates with 20 steel needles that deliver 3,500 blows per minute, making it suitable for bodywork in the automotive industry as well as industrial applications where precise cleaning is required. It features stepless control of the impact frequency for controlled operation and a quick-change system for efficient workflows. The ergonomic handle is coated with non-slip rubber for a secure grip during extended use, while the two-part housing design simplifies maintenance tasks. Technical specifications include an air connection of 1/4 inch (6.35 mm), an operating pressure of 6.2 bar (90 psi), an air consumption of 198 liters per minute (7 cfm), and a recommended hose inner diameter of 10 mm (3/8 inch). The tool measures 330 mm in length and produces a sound pressure level of 93 dB(A) with a sound power level of 104 dB(A). Vibration values are 9.6866666 m/s² (ahd) and 1.5 m/s² (K). This needle scaler offers a middle ground for cleaning that is finer than rust hammers but more aggressive than blasting methods, making it particularly suitable for surface preparation in metalworking areas. The construction emphasizes durability and reliability for professional applications where consistent performance is essential.
