TOOLTALK Hand Deburring 101 Hand deburring tools have been around for over 50 years and have been a crucial part of every industry where metalworking and metal cutting is involved. Hand deburring often involves using a blade as an abrasive to smooth edges. The two most common types in the industry are B10 and E100 blades. Both feature a unique offset pattern where the cutting edge glides against straight-edge or even hole-edge pieces. Originally developed by the VARGUS company in Israel, the unique geometry of these blades allows easy removal of sharp burrs left from metal cutting or drilling. A simple and quick movement of the tool provides a professional finish. Deburring blades typically are made of HSS (high speed steel) for standard jobs, but they also come in a variety of components such as Cobalt, TiN (Titanium Nitride Coated), Carbide and even Diamond Coated. Each of these styles allows deburring of different workpiece materials. The type of metal that the blade is made from is crucial to the deburring process being successful. The Go-To Blades As mentioned earlier, the two most common blades in the industry are the B10 and E100 blades. Both blades feature a different size and shank dimension. The B10 is smaller in size and is suitable for most standard metal and plastic jobs when the pressure that B10 needs to be applied is relatively normal. It is also better for compact spaces. Handles and holders designed to hold the B series can hold every style of blade. The E100 is preferable where heavy-duty deburring is required. Both blades have the same geometry and come in a variety of different materials. Handles and holders designed to hold the E series can hold every style of blade. E100 Besides the materials the blades are available in, they can also come in different patterns as well. Different head styles of the B and E series are available for cross-hole deburring, back-edge deburring, scraping, and other uses. These unique blade patterns can assist with all sorts of unique workpieces. Looking for Metalworking Tools?
