Woodworking Tools—The Scraper

Published On: August 25, 2020

Scraper is the main tool for scraping. High speed steel(HSS) can be used to manufacture scrapers, which endows the scraper good wear-resistance. But there are both advantages and disadvantages. They are hard to be ground and their blades are not easy to be polished. So we rarely use this kind of material to produce scrapers. Then here comes another main material we use to manufacture scrapers—high carbon tool steel. This kind of material will give your tool better wear and heat resistance, which means carbide scrapers have a longer service life than HSS scrapers.

Materials make different scrapers, so do scrapers’shape. Carbide scrapers with different shapes have their favorable position for the use of their skill. Due to the places we need to use them, we mainly divided them into three types: flat scrapers, triangular scrapers and crescent scrapers.


The flat scraper is the most widely used type and mainly used to scrape the plane. Such as flat, flat track, working table and other similar planes. But it can also be used to scrape the outer surface.

Triangular scraper is one of the tools used to scrape bearing bush. Its fracture surface is a equilateral triangle. For the convenience of cutting edge grinding, the middle of each face is provided with an arc groove to narrow the grinding area. But triangular scrpers are hard to change the direction once they are started to work. After the processing, there might be some chatter marks. So triangular scrapers are usually used cooperatively with crescent scrapers.


Crescent scrapers are mainly used to scrape the inner surface, such as the inner hole of the movable bearing. Crescent scrapers are usually worked as road roller, they both are pushing straightly forward on the surface. So they can be used to eliminate the chatter mark.


Scrapers are tools must be used in woodworking. Also, scrapers are the main tool used in scraping. Scrapers’ materials and types will make a difference in their work efficiency. Hope this article made you know more things about woodworking.
