Step 2: make sure the collet and the router bit are clean.

Crust and sawdust could cause increased friction, therefore the temperature of the router will rise rapidly, and the durability of this tool will be decreased. So, make sure that you have cleaned the collet and the bit before using them. It will make your router work better.

Step 3: insert the router bit into the collet.

Insert it into the collet until the shank reaches the bottom of the collet.

Step 4: adjust the height of the router bit

When the shank reaches the collet’s bottom, draw back the bit slowly, about 1/8 – 1/16 inch (it up to the recommendation of the manufacturer).

This step is ultimately important. Because if you skip this step, and tighten the collet nut when the shank still reaches the collet’s bottom, you will cause the squeeze between the collet and the shank. And this squeeze will create so much fiction during the operation.

If you put the shank touch the collet’s bottom first, and then draw it back a little, it will create a safety space between the collet and the bit and the issue will be fixed.

Other ideas is: during the operation, because of the friction between the bit and the material, the bit will get hot and increase its size. And if we do not keep a space between the collet and the router bit’s shank, the bit will be broken.

After draw back the bit, remember to tighten the collet nut to hold it.

Step 5: tightening the collet nut

Use an appropriate wrench to tighten the collet nut, with a firm pressure, but not so hard.
