A jet chisel (also called needle scaler) is a pneumatic tool made up of multiple thin steel rods (“needles”) that rapidly move back and forth when connected to compressed air. The vibration of the needles chips away rust, old paint, scale, and marine growth on metal surfaces.
Think of it as “pangbaklas ng kalawang, pero industrial version.”

Purpose:
• Remove rust, corrosion, and scale from steel surfaces
• Prepare metal before painting, welding, or coating
• Clean areas where grinders and wire brushes can’t reach (corners, tight spots, edges)
• Reduce manual scraping time and physical fatigue

How to Use:
1. PPE First
• Safety goggles / face shield
• Ear protection (maingay ’yan)
• Gloves
• Mask (dust/rust particles)
• Proper coverall
2. Check the Tool
• Inspect air hose, connectors, and needles
• Ensure air compressor pressure is within recommended range (usually 90 psi ± depending on tool)
3. Connect to Compressed Air
• Attach hose firmly
• Open the air valve gradually
4. Operate
• Hold the tool with both hands
• Press the needles gently against the surface — do not push too hard
• Let the vibration do the work
• Work in steady strokes
5. After Use
• Shut off air supply
• Clean and oil the needles to prevent rust
• Store in dry location
