Here is the step by step tutorial on How to Sharpen Drill Bits on a Bench Grinder:

Step 1: Know Your Drill Bit

Before you start sharpening your drill bits, it’s important to understand the type of bit you have. Different drill bits require different sharpening techniques. If you don’t know which bit you have, take a look at the drilling hole in your woodworking tool head. This is where the bit screws into the chuck (or motor). There will usually be a number engraved on this side of the bit. If you don’t have a drilling hole in your power tool head, or if the number isn’t etched properly, then it’s likely that your bit is made of tungsten carbide and requires a different sharpening technique.

Step 2: Understand Why Drills Chip and Dull

Drills are designed to drill through hard materials like concrete and stone. However, over time, these materials can cause the bit to become dull. This is why power drills start chipping and deteriorating early in their lifespan because the bits are too dull to drill properly.

Step 3: Prepare Your Bit to sharp

Before sharpening your wood drill bit, you need to prepare it correctly. First, remove the burrs (small bits of metal that can grip the edge of the bit) using a bench grinder sharpening stone or sharpening wheel. Second, lubricate the bit with drilling lubricant. This will help prevent irritation and grinding process during sharpening.

Step 4: Choose Best Bench Grinder

Now that your bit is prepared and lubricated, you can start sharpening it on the bench grinder. Choose the correct wheel for the size of the bit you are grinding. Small bits should be sharpened using a small wheel, while larger bits should be sharpened with a large wheel. Be sure to wear protective eye protection that is safety goggles and hands-on gloves when sharpening bunch of drill bits on the bench grinder.

Step 5: Practice Holding the Bit

Before you start sharpening the drill bit, practice holding it in the correct position. This will help prevent injury and ensure that your bit is grinding evenly. Be sure to hold the bit in a neutral position, with the cutting edge facing towards the grinding wheel.

Step 6: Cut the Landing

After grinding the bit to the desired sharpness, it’s time to cut the landing. This is the small edge on the bit that sits opposite the cutting edge. To do this, hold your conventional drill in a hand-held drilling position and use a bench grinder wheel to shave off tiny bits of metal from around the landing.

Step 7: Shape the Chisel

After cutting the landing, you can use a bench grinder chisel to shape the bit. To do this, hold the bit in a drilling position and use the grinding wheel to sharpen the chisel’s sharp edge. Be sure to maintain pressure on the chisel while sharpening, so it doesn’t jump out of your hand.

Step 8: Shape the Landing

Next, you must shape the landing. This is the small edge on the bit that sits opposite the cutting edge. To do this, hold your drill in a hand-held drilling position and use a bench grinder wheel to shave off tiny bits of metal from around the landing. Be sure to maintain pressure on the chisel while sharpening, so that it doesn’t jump out of your hand.

Step 9: Combine Cutting, Shaping, and Rotating

Once the cutting, shaping, and rotating are complete, it’s time to combine the steps. This will ensure that the bit is sharpened evenly and correctly. To do this, hold your drill in a drilling position and use the grinding wheel to drill bit sharpener both the edge of the chisel and the landing. Be sure to maintain pressure on the chisel while sharpening process, so that it doesn’t jump out of your hand.

Step 10: Repeat the process for Perfection

It may take up to a hundred attempts to get the drill bit’s two lips symmetrical. That’s to be expected, and it takes a lot of patience. However, keep trying! To prevent favoring one side over the other, you should frequently spin the bit on which side you’re working. Don’t try to “feather” a sharp tip by lightly pressing the drill bit into the belt sander or grinder. Always make deliberate cuts. This is typically accompanied by uneven lips or, worse still, rolling your lip so that it no longer cuts. You’re ready to begin drilling if you’ve practiced a bit with your landing and chisel and been able to roll and shape it successfully.

Step 11: Start Drilling Operation!

Finally, it’s time to drill! To do this, hold the bit in the drilling position and use the diamond grinding wheel to sharpen both edges of the chisel and the landing. Be sure to maintain pressure on the chisel while sharpening so that it doesn’t jump out of your hand. Start by drilling a pilot hole before inserting a bit into the material. Use a spade sharp drill bit if possible; its round shape will help prevent tear-out when drilling into hard materials such as granite or quartz.
