A plunge router base is commonly used for a woodworking router and makes a great tool for creating various edges and shapes to a piece of wood. There are a hundred different kinds of bits that can be installed or used with a plunge router, and each one features a different kind of way to use it. If you are wondering how you can change plunge router bits on your own or how to replace the router bits in order to create a different edge or shape for your next wood project, below you will learn how to replace or change plunge router bits. First, here are the tools and materials that you will need.

Step 1 – Ensure Bits are Clean

Before you install or change anything else, make sure that the router bits you're about to use are clean. It's important that they are free of pitch and most important of all they must be sharp. You won't get great results if your bits are chipped or dull. If the bits have excessively burned, they must be replaced or at the least be sharpened. So remember, before you proceed, make sure that the bits are clean and sharp to ensure perfect results for your woodwork.

Step 2 – Remove the Previous Bits

In order to install new bits into your plunge router, you'll need to take out the old bits. The bits are attached into the router's collet. They are somewhat seated to the collet. Release the collet, ensuring that the bit will fall off safely unto a soft surface. Simply loosen the bit until it falls off or is completely detached to the collet. Get a shop towel and lay it flat on to the table where you can release the bit carefully. Remember that bits can easily break, and it's important to handle them gently so you can still reuse them later on. While it's easy to loosen up a bit and take it off from the collet, preparing a soft surface still helps in case it slips from your hands.

Step 3 – Insert the Router Bits

Now it's time to install the router bits into the plunge router's collet. Do not tighten your collet while the bit is just seated. Make sure that you insert your bit all the way up until the bit's shank reaches the bottom of the collet. Before you tighten the collet, ease it out about 1/8 to ¼ inch before you finally tighten the collet. Once your bit has been tightened, there must be less than ¾ inch length of its shank inserted into the collet. If in case your bit's shank is already too short to accommodate ¾ inch in the collet, remove and replace it. It will not give you the correct results, and it will only break the bit further if you force it.
