How To Sharpen Drill Bits By Hand

Are you hardly trying to drill something, but the bits are not performing the way it was performing earlier? It might be that a few of your bits are bad, and you are landing up with inefficient drilling performance.

Well, are you thinking of rushing to your nearest hardware store to purchase a new box of drill bits? Why don’t you give it a try by yourself?

The sharpening process of a drill bit is quite challenging but not impossible. Following a few simple techniques, you also can make this so-called impossible task “I M POSSIBLE.”

Let me assist you in this regard, and I believe after completing this D.I.Y. project, you will be able to sharpen drill bits without any hassle.

Using a jig, you can make sure that your drill bit is ground well to an accurate angle. If a jig is unavailable to you, you can prepare one for yourself.

So, without further delay, let’s start.

Step-by-step process of sharpening drill bits

Required equipment:

  • A dull drill bit.
  • A bench grinder.

Part 01: By utilizing a drill sharpening jig

Step 1 – Place the dull drill bit into the jig

When everything is ready to sharpen the dull drill bit, place the drill bit inside the jig. Thus, the edge of the drill bit is slightly tilted. Ensure the drill bit is placed into the slot perfectly.

The drill bit has to fit directly at the middle trench of the jig.

  • After that, put the drill bit head near the wheel of the grinding. But remember not to put the drill bit head against the wheel of the grinding until you switch the grinder on.

Step 2 – Start Grinding 

Switch on the grinder, and the drill needs to push a bit toward the grinding wheel. Use your one hand to glide the polishing jig to and fro, and using your other hand, hold the drill bit counter to the grinder.

  • The drill bit needs to be turned clockwise slowly.
  • Make sure the edge of the drill bit is symmetric as much as possible. This task will become a lot easier as you are operating the task with a jig. If you were grinding the drill bit with a free hand, maintaining this task would be harder.

Step 3 – If required, dip the drill bit head to let it cool

If you need to do grinding a lot, then dip the drill bit head every minute into warm water to let it cool. Until the head of the drill bit gets even sharper, continue grinding.

Step 4 – Do a trial run after you finish the grinding

Once you accomplish grinding the drill bit, it should perform better than before. To make sure that the drill bit is sharper than before, you can give a trial run on a plank of wood or on a metal surface.

  • When you are drilling on metal, make sure you are giving a good press to the drill. Because only a sharp drill bit is not enough to do drilling on a metal, you need to put a lot of pressure on a metal surface. So, a handy drill may not be workable.

Part 02: Preparing a jig for drill sharpening

Step 1 – Take a piece of brawl wood

You don’t need to sweat your forehead to make a jig because a small plank of offcut-sized wood will be enough to make a jig.

However, look around for an offcut-sized wood, and it has to be durable enough. If the measurement of the wood is 12” X 4”, then the size is good enough.

Step 2 – Measure it and mark it with an angle of 59°

For a drill bit, a 118° angle is an ideal one. But to attain this angle, all you need to do is estimate and streak the wood with an angle of 59° before you proceed to perform the cutting performance.

  • It will be helpful if your table saw contains a protractor. Then, it will be easier for you to set the 59° angle.

Step 3 – Cut the slot, following the angle mark

Switch on the table saw and push the wood slowly, headed for the table saw blade. This way, the wood can pass through the blade thoroughly. Keeping the wood straight is necessary, and for this, you can use a glide without any confusion.

  • V-shaped cutting will give you a better result. If you do so, the drill bit will not displace when you hone it.
  • Note down: Safety goggle is mandatory during this type of operation. Also, your hands should not come near the blade of the saw.

Step 4 – Inspect the slot

Once you have created a slot into the wood, remember to inspect it to confirm that the slot is excellent enough to fit the drill bit into it. If the drill bit can’t be placed into the slot, you can trim it a bit wider.

  • Keep your eagle eye not to cut the slot much wider. If you do so, the drill bit will not take place in it.
WARNING: If your hand gets too close to the grinding device, you may lose some of your skin. To remain safe, HAND GLOVES ARE PROHIBITED. Let me tell you why. Hand gloves can get stuck to the sharpening device, and thus, they may pull your hands into the device. Be careful while working with the grinding device because your position is essential for safe operation. Also, don’t forget to wear a pair of eyeglasses.
