But hole saw sharpening is not so easy as most people consider. In fact, it is way tougher than sharpening the circular saw or table saw blade. It needs penultimate precision, and so is challenging enough to test your skills. 

5 tips on How to Sharpen A Hole Saw

Step 1: Using A Universal Sharpener 

You can use a universal sharpener to remove the hole saw dullness. At first, hold the power saw firmly with your non-dominant hand. Find the vice-grip of the sharpener and then locate the drill end. Now, carefully place the hole saw in the drill end. 

Since the vice grip drill end is disconnected, you will have to fix it with the correct fitting. If you can’t identify the drill end, you might follow the below-mentioned tip. 

If you have ever seen a standard drill, the drill end will be similar to that of the drill’s chuck grip. The end accommodates a twisting head. It is easily evolvable to attach and fix any pieces within it with any length. 

Your sharpener will come with a key to fix the chunk grip. Use the key to tighten the sharpener grip to hold the hole saw firmly. Make sure you don’t over pull the saw. Otherwise, the saw teeth will get damaged. 

Step 2: Set Up the Sharpener 

At first, loosen the grip head of the universal sharpener. You can use the key provided with the sharpener to loosen the head grip. 

Once loosened, put the hole saw on the sharpener head. The teeth of the hole saw should rest on the sharpener blade. The teeth resting on the saw needs to be gentle and not firm. Fix the hole saw teeth on the sharpener blade by tightening the screw knob. You can use the key or screwdriver to fix the knob firmly. 

Make sure the hole saw doesn’t move once you start the sharpening process. If any movement happens, it will ruin the entire project. You will also have to place the teeth properly. Use the head angle changer of the sharpener to adjust the teeth quickly. You will find the head knob changer right at the front of the tool. 

Step 3: Mark the Starting Point 

A hole saw sharpening process requires you to complete an entire circle to perform the task. It is necessary to avoid dual revolution without even understating when and how did the second round happen. If you perform the second revolution unknowingly, it will damage the hole saw teeth. 

So, fix the starting point on the hole saw and use a pencil or permanent marker to identify the beginning point. It will help you avoid the unnecessary and harmful second sharpening revolution. So, your hole saw will become accurately sharp. 

Step 4: Adjust the Dust-Collector Hose 

When you sharpen a hole saw, the workplace will become dirty with specs of dust. So, you might face difficulty in seeing the hole saw. Also, it might harm your eyesight. So, attach a hose with the vacuum cleaner or shop-vac at your workshop. 

In most cases, the universal sharpener will come with a hose attachment for dust collection. You will have to place the hose right under the attached saw with the sharpening blade. When you set up the dust collector hose correctly, it will accumulate the flying metal dust to keep the workplace neat and clean. 

Step 5: Start the Sharpening 

Once again, check that the hole saw setup, shop-vac connection, and the head grip fixing is all done correctly. Then, start the sharpening machine. Once the machine’s blade starts rotating, press the hole saw firmly against it. 

Hold each tooth of the power saw against the blade for two to three seconds. Then, twist the saw to shift to the next teeth. You will have to repeat the sharpening process until you reach the last tooth of the hole saw. 

This way, you can quickly sharpen all the teeth of the hole saw without overdoing the process.

How Do You Sharpen a Metal Hole Saw?

If you’re looking to sharpen your metal hole saw, there are a few things you’ll need to take into account.

The first is the type of hole saw you have – whether it’s High-Speed Steel (HSS), Cobalt (Co), or Carbide-Tipped (Ct). Each type of hole saw requires a different sharpening method, so be sure to identify your saw before starting.

Second, you’ll need to consider the size and shape of your hole saw. Smaller hole sizes will require a different approach than larger ones.

Finally, you’ll want to think about what type of sharpener you have on hand – an electric grinder or a handheld file.

With all that in mind, let’s get started! For HSS and Co Hole Saws:

1. Begin by cleaning off your hole saw with some soapy water and a brush. This will remove any built-up debris that could clog up your sharpener.

2. Next, use a marker to draw a line around the circumference of the teeth. This will give you a guide for how much material you need to remove during the sharpening process.

3. Now it’s time to start grinding away at the teeth. If using an electric grinder, hold it at about a 30-degree angle and make sure not to overheat the metal. Work slowly and steadily until you’ve reached your guide line – don’t go too far beyond it!

For best results, use coarse grit sandpaper (60-100) followed by finer grit (200-400). If using a handheld file, start with coarser grit and move down as needed; again, be careful not to overdo it on the filing front. You can always take more material off but putting too much back on is harder (not impossible) to fix!
