CS Unitec’s needle scalers are perfect for strong, hard-working crews that need to prepare or repair metal and concrete surfaces. This line of heavy-duty needle scalers for concrete and metal are ideal for texturing concrete, cleaning weld seams/joints, removing coatings and corrosion, with the ability to adjust to contours and cleaning irregular surfaces. Needle scalers and chisel scalers convert in seconds with optional head or when purchased as a Kit.

Models include:

  • Vibro-Lo™ models with integrated vibration reduction technology operate with 8x less vibration than standard models, reducing the risk of vibration-related injury. An optional dust shroud gathers dust and debris during operation, improving workplace cleanliness and improving environmental safety and protection.

  • Vacuum System needle scalers include an integrated dust shroud for dust-free work when used with an industrial vacuum. They are ideal for cleaning and stress-relieving weld seams and joints, texturing concrete, and removing coatings, corrosion, and other accumulated materials on applications with hazardous airborne particulates.

  • Standard needle scalers with inline, pistol and semi-pistol grips and optional dust shroud to collect dust and debris

  • ATEX-Certified models are specially designed for use in hazardous areas and EX Zones. Fully certified to the EX II 2Gc IIA T4 under the European Directive 94/9/EC classification, pneumatic power and Copper-Beryllium needles make them safer in hot work zones. Paired with an ATEX-certified dust extraction vacuum, they can prepare surfaces, dust-free in dangerous applications.
