What variable speed router do I need

It is a common question during use any router that why variable speed router is so important? Let me clear, what variable speed router do?

That is called variable speed router which we can regulate the speed as per our need. There are some task that we need high speed rotation and we need slow speed for some other task in the wood working life.

Here we are going to discuss about the speed variation of the wood router. You can find so many router in the market. But variable speed router should be in your workshop.

Discuss About Variable Speed Router

Here are two types of router bit. One is 3 ½ inches diameter and other is one inch diameter.

Two router bitsThe booth router bits can make different size of holes in the wood panel. We have drawn two rounded holes on the wood.

Look at the picture.

As par geometry the periphery of the 3 ½ inches diameter is near about 11 inches. And the circumference of the one inch diameter is near about 4 inches.

Holes drawing on the woodWhen any router rotate with 22000 RPM, the one inch router bit spinning speed across the cutting circumference will be 120 mile per hour.

On the other hand with the same rotation speed the cutting spinning speed will be 200 mile per hour on the periphery of the 3 ½ inches diameter hole. Which is not good for the router bit. Rule is that the cutting speed of bigger size router bit is higher than the smaller bit.
