The industrial and manufacturing sector has advanced exponentially, particularly with regard to precision engineering. However, there are still situations in which you will need an engineer's scraper for some manual work. Basically, these tools are designed to facilitate the removal of excess material from manufactured parts so that they can fit together. For example, a scraper is handy for eliminating burs that would prevent a shift from fitting into a tube. If you are looking for a good scraper, it is important to understand the pertinent blades. These will determine usability for different applications and long-term efficiency. Here are some crucial blade factors to consider when purchasing an engineer's scraper.
The scrapers in the market are categorised according to the design of the blade. This is the most critical aspect in the function and application of the tool. The flatbed scraper is the most efficient product in the group. As implied, the blade is straight and flat, and it has a sharpened edge to facilitate scraping. Triangular scrapers are built with a long triangular blade with a tapered end. The sharpness allows the tool to scrape corners, edges and holes. Curved blade scrapers have a slightly bent design to scrape items with curved surfaces.
There are two primary materials used in fabricating engineer's scrapers. These are tungsten carbide and high speed steel. Tungsten carbide is a material formed by combining carbon and tungsten in equal parts. The material has high density and is extremely strong. Tungsten carbide scrapers can handle most materials used in fabrication, which makes this option great. However, the cost of purchase is considerably high. High speed steel is made by combining steel with elements such as molybdenum, tungsten, cobalt and chromium. This material is stronger than other common types of steel and is resistant to rust. It is considerably cheaper than tungsten, but the lifespan will be a shorter.
Removable or Non-Replaceable Blades
You can choose an engineer's scraper with removable or permanent blades. The removable option is favourable because you can substitute blades quickly if the original is damaged or becomes blunt at the middle of a project. You can choose replaceable blades made from tungsten or high speed steel. Non-replaceable or permanent blades are normally made from high speed steel. This is because the cost of making the entire scraper shaft and the blade using tungsten carbide is extremely high.
Finally, you should consider getting powered engineer's scrapers since these are more efficient than the usual hand tools.Share
