Straight Needle Scaler · Model: RH-460

Model: RH-460 迷你除锈机
The RH-460 Mini Compact Pneumatic Air Needle Scaler (Model RH-460) is a straight needle scaler for fast, even descaling on flat and gently curved surfaces. A dense cluster of hardened needles blasts away corrosion, old coating and weld residue while leaving the parent metal intact, making it ideal for fabrication shops, marine repair and structural steel maintenance. The inline body is easy to control along beams and plates, and the pneumatic drive delivers continuous impact without overheating. JIAJIE builds these units with wear-resistant internals and a balanced weight distribution so operators can hold a steady pace on large areas. Spare needle sets, matched air fittings and custom branding are available on request.
