The most common type of chain that you will find in all the modern chainsaws is Semi-Chisel, Low Profile and Chipper. They have been proven to deliver the best performance with minimum kickback. These chains are almost the same with a slight difference in their design of blades.

Why the Chain gets dull?

The chain of a chainsaw gets dull due to its use. The more you will use a chainsaw, the duller it will get.

The thing is that, you will never get the same performance out of a chainsaw after few uses.

Why the Chain gets dull?

The chainsaws work with tremendous force and the saw chain takes most of the force. It’s the most crucial part of a chainsaw.

The blades that are connected with the chain push against the wood and that friction takes away the sharpness of the blades.

This friction also produces heat which is also responsible for the wearing off the blades. The more you will force a saw against the wood, the more it will heat up and decay.

If you use the best professional chainsaw to cut something other than wood. Something that is harder than wood then it would have to struggle against more friction and the result would be more decay.

A layer of wood also gathers on the chain which is also responsible for the wearing off of the blade. They seriously impact on the efficiency of the whole saw chain.

Then, there is rust. If you leave your chainsaw open wide for a long time, whole army of rust will try to take over the blade as there is no coating on the blade. These rusts are as same as the gathered wood and they can make the chain weak.
