Cemented Carbide Woodworking Tools Application

Since cemented carbide woodworking tools are used for working solid wood, such as logs etc. Its application also includes man-made products based on wood particles, fibres or chips, such as chipboard, particle board and medium and high density fiber boards (MDF/HDF), the different types of corrosion are important:  solid wood contains organic acids and other compounds that degrade the binder in the tool material and cause outbreak of the hard WC-particle from the matrix and thus wear the tool material.

Man-made wood products contain organic binder material, based on compounds such as urea, formaldehyde, wax, glue fillers etc. and possibly laminated with plastic layers, such as melamine. The temperature may get very high (>500°C) when working these wood products and then the content of the product will degrade into corrosive compounds chemically attacking the cemented carbide binder.
Furthermore the high temperature may result in oxidation of the cemented carbide binder, also degrading and wearing the cutting edge.
