Why We Choose Tungsten Carbide Inserts For Wood Cutting

Published On: August 18, 2020

Speaking of woodworking, we may associate it with handicraftsmen. With a special tool in their hands, craftsmen worked hard in workshops, and sweat dripped down from his forehead to the wood he was processing. However, we are living in the 21st century. Most of the work has no longer needed to be done with human force. There are machines with higher efficiency and higher precision that can produce more projects and save costs.

But how do these machines cut woods? We can watch it on television, and with waves of tremoring and some noisy sound, finished woods comes out. We actually don’t know how these woods comes out. If you’ve ever looked closely, you can find there are small pieces of knives loaded on machines.


What are they?

We call them wood cutting tungsten carbide inserts, and now they are used in wood processing machines. But it doesn’t mean we have only one choice. In fact, years ago there’s a kind of flat knife which are popular among producers. But why we can hardly see the traditional flat knife in the factory or in personal workshop?

There are reasons.

1. These tungsten carbide cutting knives for wood will not produce burn marks on the cutting surface, but traditional flat knives will. When it has been used for a long time and its cutting edge is getting blunt, or when feed is temporarily stopped, cutting heat will remain burn marks on the surface.

2. Traditional flat knife has a bad performance in temperature distribution, and when your tool gets hot in its working, the cutting edge will also sustain higher heat, and its passivation speed will be improved, which may cause the tool to lose its original stability. But none of those carbide blades with aluminus alloy blade body will have these problems. These tungsten carbide inserts with better heat dissipation have indicated stability and promised a longer service life.

3. Small blades loaded on the spiral cutter heads will produce smaller wood chips, which means you can easily discharge wood chips away from the wood surface. But traditional flat knives are prone to produce large signs of damage on the wood. Due to their large force area, traditional flat knives are easy to form cutting deformation and will give you a ragged cutting surface.


So why do we choose tungsten carbide inserts for wood cutting?

All in all, there are too many advantages that make us choose tungsten carbide inserts for woodworking. There may be some people who are using traditional knives still think traditional knives are better. I can’t agree more with that. But with the progress of times and the development of science and technology, more things will be outdated. Not because they don’t have advantages, but because there are better choices for us.
