Have you recently tried to drill through something and noticed that your bits are not cutting as they used to cut? Maybe some of the bits are in terrible condition.
This makes it impossible to drill through soft metals and wood without creating high shrieking squeaks and a plume of smoke.
The quickest and easiest way to sharpen drill bits is with a drill bit sharpener like the Drill Doctor 500x and 750x models.
Well, before dashing to the nearby hardware to get yourself a box of new drill bits, try the following sharpening procedures.
The drill bit sharpeners are so easy to use, you’ll end up saving money because you’re not constantly buying new bits.
Drill bit sharpeners have grinding wheels that remove metal from the tips of the bits until the edges are sharp again.
Plus, using dull drill bits is very dangerous. They can break and hurt you. So, it’s always best to use sharp drills that can withstand the task.

Is it worth sharpening drill bits?
One of the most common questions is always if it’s worth sharpening your drill bits. It seems like it’s easier to buy new ones but it’s wasteful and unnecessary.
If you spend a lot of time working with drills, you should really invest in a drill bit sharpener. It’s going to save you money in the long run.
Since you spend time working with tools in the shop, you know how annoying a blunt drill bit is. Once they get dull, the bits just don’t cut like they used to and this makes your work harder.
So, to save time and money, a drill bit sharpener is a true lifesaver.
Think about it like this: how long do your drill bits last?
Sometimes, I break at least one a day while working. If I’m lucky, a good quality bit lasts me up to three weeks.
But since I have a drill bit sharpener, I can reuse the dull and broken one (as long as it’s still sharpenable, of course).
When you use dull drill bits, it slows you down. Nothing compares to a sharp crisp edge of a new (or newly sharpened) drill bit.
You can work quicker and more efficiently without putting your hands in danger.
Is the drill bit sharpener worth it?
Of course, it is, because a tool like the Drill Doctor makes drill bits like new. In some cases, they work better than new ones because if you split the point on them, they become sharper and work better.
But even with very dull drill bits, you can revive them and make them sharp again in seconds. If you want to save a ton of money, you can take used and junky drill bits and make them like new again.
This way you don’t need to spend money on expensive drill bits.
According to the DIYhelpdesk, a good drill bit sharpener can sharpen over 200 drills before you have to replace the grinding wheel – so that’s a lot of value for your buck.
Drill sharpeners work for 2.4mm to 12.5mm drill bits so you can get a lot of use out of them.
What is the best drill sharpener?
The two most popular and effective drill sharpeners are the Drill Doctor models 500x and 750x.
They are relatively affordable so they make a great addition to any tool shop or handyman’s tool kit.
Even if you just like to do DIY projects, you’ll still benefit from a drill sharpener, because they are easy to use for everyone.
When you’re working on a large project and drilling through dense hardwood, your drill bit can become dull within minutes!
Just imagine how many you need for working in a huge house. So, if you work with hardwood and steel, you definitely need to get a drill bit sharpener to save you time. Simply restore the cutting edge and get back to work.
The Drill Doctor 750x is a great option:
It sharpens multiple types of drill bits, therefore it’s very versatile for your garage or shop. You can sharpen drill bits of any material, including steel and cobalt in no time.
A tool like this allows you to sharpen your bits, split them, and align them, which makes your life easier.
Just think about how much waste all those dull drill bits are creating. Like me, you probably have boxes or containers of dull and useless drill bits lying around.
With a sharpener, you can reuse them all again! Out of all the Drill Doctor sharpeners, the pros recommend the 750x because it works extremely well.
If you already have your handy drill bit sharpener, here’s how to use it properly. Follow our tips and your drill bits will look and work like new!
1. Connecting to a Drill
1. Ensure that the jaws mounted on the drill chuck are tight and fully closed. You should always use a drill with a 43mm collar and a 13mm (1/2 inch) chuck.
2. Fit the drill bit sharpener onto the drill.
3. You should loosen the wingnuts to enable the outer tube slide over the chuck.
4. You should set the outer tube to grip the drill’s collar and not the chuck. The drill should be connected to the drill bit sharpener by friction only.
2. Properly sharpened bits
You should know that your bits are properly sharpened after identifying the following characteristics.• A sharp point at the center of the bit.• Two equal and sharp cutting edges.• Two trailing edges positioned slightly lower than the cutting edges.

How to Use Drill Bit Sharpener
1.You should connect the drill and the drill bit sharpener then clamp the drill into a vice holding the sharpener in an upright position.
2.Connect the drill to the main supply.
3.Place a single drill bit into the appropriate hole. Note that some drill bit sharpeners are not suitable for sharpening masonry bits.
4.Pull the trigger mounted on your drill. For better sharpening, exert a considerable downward pressure onto the bit while making back and forth rotations of about 20 degrees. While inside the drill bit sharpener, you must keep the bit in motion.
5.After approximately 5 to 10 seconds of sharpening, you should remove the drill bit to reduce damages.

• Overheating is experienced whenever the tip of the bit starts turning blue. In this case, you should reduce the amount of sharpening time and exerted pressure. It is advisable to cool the bit with water between the sharpening cycles regularly.
• In the case whereby one edge becomes more extended than the other, it is advisable to sharpen the longer side to attain the required length.
• You should use a bench grinder to rough broken bits into shape. This is because sharpening broken bits rather than blunt bits takes much time to attain their original shapes.
• Always ensure that both sides of the drill bit are exerted to the same amounts of time and pressure while sharpening.
6. Repeat the above steps whenever necessary.
Drill Bit Sharpening Attachments
If you already own a bench grinder, all you need is the drill bit sharpening attachment. Since it’s an attachment, it’s removable and you can use it when you need it. These attachments are usually more expensive, so you really need to think of it as a long-lasting investment. It is durable, so you can sharpen thousands of drill bits.

Why is this tool useful?
You can set it to sharpen at any angle between 90 degrees and 150 degrees which means that it sharpens all point angles. As well, the cutting edges are sharpened symmetrically so your edges are always equal and help your drill last longer. The best part about this attachment is that it creates a 4 faceted point and that means superior performance for you when you use the drill bits.
How to sharpen drill bits
- Take out the setting template and set the distance of the universal support from the stone.
- Mount the base plate carefully until it locks securely.
- Now, set the clearance angle. Check your setting template for the recommended angles depending on the material you use and the drill bit dimensions.
- Take the drill bit you want to sharpen and mount it in the holder.
- Set the protrusion with the measuring stop on the guide.
- Now, it’s time to align the cutting edges. They must be parallel with the horizontal lines.
- You can now start to sharpen the primary facet first.
- Position the holder so the lug rests on the primary stop, marked with a P.
- Push until the drill bit actually touches the stone.
- Now, you need to set your cutting depth. Use the cutting screw and lock it in using the locking nut.
- The edge is ground once the grinding noise stops sounding like it’s working against friction.
- Turn the jig around to sharpen from the other side.
- At this point, you can start to grind the secondary facet, just like the primary.
