Needle Scalers

Shop Needle Scalers at Acme Tools.

Needle scalers, known in various contexts as needlegun scalers or needle-guns, are versatile tools primarily utilized in metal preparation, efficiently stripping surfaces of rust, mill scale, old paint, and corrosion, making them indispensable for tasks such as texturing concrete, restoring stone, eradicating saltwater corrosion on ship hulls, or meticulous cleaning of weld seams and joints. These pneumatically driven instruments, powered by compressed air, function through a piston mechanism where numerous chisel-like needles rapidly thrust back and forth, propelled by air pressure, effectively catering to intricate metalwork across diverse applications. Available in straight or pistol grip forms, needle scalers demand careful selection based on specific job requirements, considering key factors like blows per minute (BPM), air consumption rates, and the quantity and length of needles — where a higher BPM and more needles contribute to accelerated task completion, and the tool's length becomes a crucial determinant when operating within restricted spaces.
