Needle scalers

Scalers (needle hammers)

— demolition hammers, in which a set of needles is used as a working tool (from 10 – 12 to 30 or more).

Scalers are relatively small in size and weight, they are traditionally made pneumatic, and the main purpose of such tools is to remove various coatings and formations (paint, rust, welding slag, etc.) from various surfaces, primarily metal. At the same time, in simple and inexpensive models, the needles are rigidly connected and move simultaneously during operation, but this format of work is only suitable for flat surfaces. Therefore, devices with floating, independent needles are more popular — they are more complicated and more expensive, but they can effectively cope with the processing of complex shapes.

In general, scalers provide quite efficient and at the same time accurate processing. The specific capabilities of such tools, among other things, depend on the number of needles: with the same impact energy, a small number of needles provides a rough and performant impact, while a large number provides a relatively accurate and gentle treatment.
