Contractors and metalworkers, this CS Unitec needle scaler means business! This heavy-duty inline needle scaler operates at 3000 blows per minute but only requires 5.5 CFM at 90 PSI - efficient and powerful. The pistol grip handle provides comfortable operation even during extended use, and at only 5.75 pounds, it's lightweight enough to handle without fatigue. The kit includes the 2B needle scaler, 19 long-lasting chisel-tip needles (3mm diameter each), PLUS 6 additional sets of replacement needles (114 needles total!). This professional-grade tool is built for tough jobs - removing rust, descaling corrosion and slag from steel, cleaning weld seams and joints, texturing concrete, and removing coatings to prep surfaces for treatment. The oversized piston with longer stroke and heavy-duty hardened anvil can handle the harshest environments. Since 1990, CS Unitec has been making top-quality tools for construction, marine, mining, and industrial applications. If you need to remove tough scale, rust, or coatings quickly and efficiently, this needle scaler kit has you covered. Tool-free needle changeover means less downtime and more productivity.
