Scrapers

Scrapers

— specialized demolition hammers (usually pneumatic) for use with working attachments of the "scraper" type.

Initially, such nozzles are actually used for scraping — high-precision alignment of various surfaces, most often metal; in addition, scrapers can scrape off rust, old paint and other similar coatings, as well as perform some other work. As for scraper hammers, they usually have a small mass and impact energy, but are capable of delivering a high frequency of blows, which contributes to productivity.
