Recommended Drill Bits for Rocks

There are many different types of drill bits, each designed for a specific purpose.

However, the main factor determining which drill bit to use on rock is the hardness of the material.

The harder the rock, the tougher the drill bit needs to be.

That said, here are some recommended drill bits for rocks:

1. Carbide-Tipped Drill Bits

Carbide-tipped drill bits are made of tungsten carbide, a tough compound that can withstand a lot of wear and tear.

The metal-carbon compound is also resistant to heat, so the bit won’t overheat when used for extended periods.

In addition, carbide-tipped drill bits are designed to stay sharp longer than traditional bits, so they can be used for multiple projects without needing to be replaced often.

As a result, they’re an ideal choice for anyone who needs to drill through rock regularly.

2. Diamond Tip Drill Bits

When it comes to drilling holes in rocks, diamond tip drill bits are some of the best available.

They’re made with a very hard material (diamonds and steel/carbide combo), which makes them able to drill through rocks quickly and easily.

In addition, these bits are also precision-made, which means that they’re great for making small, precise holes in rocks, as opposed to larger, less precise holes.

If you need to make a hole in a rock and want it to be both fast and accurate, then a diamond tip drill bit is the way to go.

For starters, check out this HIGHDRIL Diamond Core Drill Bit from Amazon.com. It features a lubricant for smoother drilling, as well as a diamond tip that can cut through rocks quickly and easily.

3. Percussion (Hammer) Drill Bits

Percussion drill bits, also known as hammer drill bits, are another great option for drilling through rocks.

These bits are designed with a special head that helps to break up rocks as you drill, making the process easier and faster.

In addition, the head of these bits also prevents the drill bit from getting stuck in the rock, which can happen with other types of bits.

If you need to drill through a lot of rock quickly, then a percussion drill bit is the way to go.

4. Masonry Drill Bits

Masonry drill bits are another excellent choice for drilling through rock.

These bits are made of carbide, a material that is very hard and resistant to wear.

The tip of the masonry drill bit is tapered, which helps it start drilling through the rock more easily.

Besides, the flutes on the masonry drill bit are designed to remove debris as you drill, which helps keep the bit from becoming clogged.

As a result, masonry drill bits are an excellent choice for drilling through both soft and hard rocks.

How To Drill a Hole Through a Rock

Now that you know what kind of drill bit to use, you’re probably wondering how to actually drill a hole through a rock.

The good news is that it’s not as difficult as you think.

Here are the steps you need to follow:

  1. Put on safety glasses. Drilling through rock can create a lot of dust, so it’s vital to protect your eyes.
  2. Place the chosen drill bit on the rock. Make sure that the tip of the drill bit is lined up with the spot where you want to make the hole.
  3. Apply pressure to the drill bit. That will help keep the bit in place as you start drilling.
  4. Start drilling. Slowly apply pressure to the drill as you start it, and then increase the speed as you go.
  5. Drill through the rock. Keep drilling until the drill bit comes out on the other side of the rock.
  6. Turn off the drill and remove the bit. Carefully remove the drill bit from the hole and set it aside.
  7. Repeat as necessary. If you need to make more than one hole in the rock, repeat steps 3-6 until you’re finished.

Tips for Drilling Through Rocks With Drill Bits

Having looked at the different types of drill bits you can use to drill through rocks and how to do it, here are a few tips to keep in mind:

1. Choose the Right Size Bit for the Job

One of the most important things to keep in mind when drilling through rock is to choose the right size drill bit.

If the drill bit is too small, it will take forever to get through the rock.

On the other hand, if the drill bit is too large, it could cause the rock to crack or break.

So, it’s crucial to choose a drill bit that is the right size for the job.

Note: The size of the bit will vary with the size of the hole you’re trying to make.

2. Use Water To Keep the Bit Cool

Another important tip is to use water to keep the drill bit cool while drilling.

The friction from drilling can cause the bit to overheat, damaging it.

To prevent this, simply squirt some water on the bit every few minutes as you’re drilling.

That will help to keep it cool and prevent damage.

3. Take Your Time To Avoid Ruining the Job

When drilling through rock, it’s essential to take your time.

Drilling too quickly can cause the drill bit to overheat and break the rock.

So, go slowly at first, and then increase the speed as you get more comfortable with the process.

And if you need a break, take one.

It’s better to take your time and do the job right than to hurry and make a mistake.

4. Use a Hammer Drill for Harder Rocks

If you’re having trouble drilling through a particular rock, it’s worth considering using a hammer drill.

These drills are designed specifically for drilling through hard materials, and they can make quick work of even the hardest rocks.

Of course, hammer drills are more expensive than regular drills, so they’re not a good choice for everyone.

But if you’re having trouble drilling through rock, then it’s worth considering investing in one.

That said, here’s a quick video tutorial on how to drill holes through rocks:


As anyone who’s tried it knows, drilling through rocks is no easy feat–but it is possible with the right tools and techniques.

So, the next time you need to drill through rock, keep these tips in mind, and you’ll be sure to get the job done right.
