This article is about how to enlarge arbor hole in saw blade. It’s a quick DIY guide that will show you how to do it quickly and easily with the help of some common tools.

Reasons Why You May Need to Enlarge Arbor Hole in Saw Blade

There are several reasons why you may need to enlarge the arbor hole on your saw blade. The most common reason is that you have switched to a different size blade and the new blade does not fit into the old arbor hole.

Another reason is that the original hole has become worn or damaged over time, which can cause the blade to wobble and make it difficult to cut accurately. In some cases, the arbor bolt may also be too short, preventing you from being able to use certain blades. Moreover, the arbor hole may have been damaged by a piece of metal that has become stuck in the blade.

How to Enlarge Arbor Hole in Saw Blade

1. Use a grinding wheel to enlarge the hole

You can use a grinding wheel to enlarge the hole. This is a quick and easy way to do it, but it can also be a bit dangerous. Make sure you wear goggles and a mask to protect your eyes and lungs from the dust generated by the grinding wheel.

2. Drill out the hole with a drill bit

If you don’t have a grinding wheel, you can drill out the hole with a drill bit. This will take longer than using the grinding wheel, but it is much safer. Just make sure you use a bit that is smaller than the diameter of the hole you want to enlarge.

3. Use a file to enlarge the hole

Another option is to use a file to enlarge the hole. This method takes even longer than using a drill bit, but it is also much safer. Make sure you use a file that has an edge with the correct shape to enlarge your hole

4. Use a reamer or tap to enlarge the hole

You can also use a reamer or tap to enlarge the hole. This method takes longer than any other because you have to make two holes to work properly.

First, drill out one end of your saw blade and then thread-tap (or cut) threads into it so that you can screw on another piece which will create an enlarged hole through both pieces when tightened down. You’ll need some kind of press device too in addition to whatever method you choose above.

5. Use a bench grinder

You can use a bench grinder to enlarge the hole. This method is very quick and easy but it will also leave your saw blade looking roughed up and weathered. It’s definitely not as nice-looking as using another technique that doesn’t involve grinding or cutting metal. If this isn’t an issue for you then give it a try!

6. Use a lathe machine

You may consider trying out some of these methods before investing in any tools if you don’t already own them (or know which ones are best suited for what jobs). You might find one of these works better than all others, depending on how big or small your arbor hole needs to be sized down to.

There are many ways to enlarge an arbor hole in a saw blade. The best way for you may be one of the methods listed above, or it might be something not mentioned here. Whichever method you choose, make sure you take all necessary precautions to keep yourself safe while doing the job! Happy DIY-ing! 🙂
