How To Lubricate Router Bit Bearings?



Router bits are essential tools for any woodworker with a router. They’re designed to cut certain shapes or edges out of a material, and they come in a variety of sizes and shapes. To make sure your bits stay sharp and reduce friction, it’s important to lubricate the bearings that the bit spins on. Read on to learn how to lubricate router bit bearings so you can keep your tools in optimal condition.

What You’ll Need?

If your router bit has bearings, you’ll need to lubricate them from time to time to keep them running smoothly. Here’s what you’ll need:

  • A small brush or toothpick
  • A can of compressed air
  • Lubricant ( WD-40 or 3-in-1 oil will work)

    To lubricate the bearings, start by using the brush or toothpick to remove any dust or debris that may have accumulated. Then, use the compressed air to blow out any remaining particles. Finally, apply a few drops of lubricant to the bearings and allow it to penetrate for a few minutes before wiping off any excess.

How to Lubricate Router Bit Bearings?

To keep your router bits running smoothly, it is important to lubricate the bearings periodically. Here is a step-by-step guide on how to do this:

  1. Unplug the router and remove the bit from the collet.
  2. Use a brush or compressed air to remove any debris from around the bearings.
  3. Apply a few drops of lubricant to the bearings. We recommend using a lightweight oil such as 3-in-1 oil or WD-40.
  4. Reassemble the router bit and replace it in the collet.
  5. Plug in the router and test it out to make sure the bit is running smoothly.

How Often Should You Lubricate Router Bit Bearings?

Lubricating your router bit bearings is an important part of routine maintenance. Doing so can help extend the life of your bits and keep them running smoothly. But how often should you lubricate router bit bearings?

The answer may vary depending on how often you use your router and the type of bits you use. In general, however, it’s a good idea to lubricate router bit bearings every time you change bits. This will help ensure that the bearings are always properly lubricated and don’t become dry or damaged.

If you use your router frequently, you may need to lubricate the bearings more often. If you notice that your bits are starting to wear down prematurely or aren’t running as smoothly as they should, this is also a sign that the bearings need to be lubricated more often.

In any case, it’s always better to err on the side of caution and lubricate more often than not. This way, you can be sure that your bits will last as long as possible and perform at their best.

What are router bit bearings?

Router bits have two types of bearings: ball bearings and roller bearings. Ball bearings are the most common type of router bit bearing. They are found in all sizes of router bits, from the smallest to the largest. Roller bearings are less common, but they are used in some large-diameter router bits.

Both ball and roller bearings need to be lubricated periodically to keep them running smoothly. The best way to lubricate router bit bearings is to use a high-quality bearing grease. This type of grease is designed specifically for bearings and will not gum up or collect dust like some other types of lubricants can.

To apply bearing grease, first remove the router bit from the router. Then, using a clean cloth or paper towel, wipe away any old grease or dirt from the surface of the bearings. Next, apply a small amount of new grease to the bearing surface, being careful not to over-lubricate. Once you have applied enough grease, reassemble the router bit and return it to your router.

How to identify when they need lubrication?

If your router bit bearings are starting to make noise or feel gritty, it’s time to lubricate them. You can tell if the bearings need lubrication if you see metal shavings on the router bit shaft or around the bearings, or if the router bit starts to vibrate excessively.

To lubricate router bit bearings, first remove the router bit from the router. Then, using a needle nose pliers, remove the innermost bearing from the router bit shaft. Be careful not to lose any of the small balls inside the bearing! Next, apply a few drops of light oil to the bearing and replace it on the shaft. Finally, reattach the router bit to the router and test it out.

Why do router bit bearings need to be lubricated?

Router bit bearings are small, precision-machined components that are subject to a great deal of wear and tear. In order to prolong the life of your router bits and keep them working properly, it is important to lubricate the bearings on a regular basis.

There are a few different ways to lubricate router bit bearings. One is to simply use a few drops of light oil, such as 3-in-1 oil or machine oil. Another option is to use a bearing grease, which will provide more protection against dust and debris than oil alone.

Whichever method you choose, be sure to apply the lubricant sparingly. Too much can cause the bearings to overheat, leading to premature failure.

What type of lubricant should you use on router bit bearings?

There are a few types of lubricant that can be used on router bit bearings. The most common type is a light oil, which will help to keep the bearings running smoothly and prevent them from seizing up. A WD-40 type lubricant can also be used, but it is important to make sure that it does not contain any silicone, as this can damage the bearings. If you are using a router bit with carbide tips, it is important to use a lubricant that is designed for use with carbide, as this will help to extend the life of the router bit.

How do you apply lubricant to router bit bearings?

There are two ways to lubricate router bit bearings: with oil or with grease. If you’re using oil, simply drip a few drops onto the bearing and spin the bit by hand to work the oil into the bearing. If you’re using grease, apply a small amount to the bearing and again spin the bit by hand to work the grease into the bearing.

Tips for maintaining your router bit bearings

If your router bit has bearings, it’s important to keep them lubricated in order to maintain the life of your bit and prevent premature wear. Here are some tips for maintaining your router bit bearings:

  • Before lubricating, always clean the bearings and surrounding area with a clean, dry cloth. This will remove any debris or dirt that could potentially clog the bearings.
  • Once the bearings are clean, apply a light layer of lubricant. Avoid using too much lubricant, as this can cause buildup and attract dirt and debris.
  • Be sure to wipe away any excess lubricant after application. Excess lubricant can seep into the router bit body and cause damage.
  • It’s important to regularly check the condition of your router bit bearings and reapply lubricant as needed. Doing so will prolong the life of your router bit and keep it running smoothly.


Properly lubricating router bit bearings is essential in order to get the most out of your router bits. Following our tips and using the right lubricants can help ensure that your router bits will have a long life and provide you with great results. If you’re still having trouble properly lubricating your router bit bearings, consider consulting with a professional or checking out some helpful videos online. With the right care, your router bits should last for years to come!
