Drilling a hole in rock may sound intimidating, but with the right tools and a little patience, it can be done with relative ease. This step-by-step guide will help you learn how to drill a hole in rock, whether it’s for making a jewelry piece or constructing an outdoor landscape feature. With the right technique and proper safety precautions, you’ll be able to make a neat, clean hole in rock in no time.

Preparing to Drill the Hole

Preparing To Drill The Hole

Gather Supplies

To drill a hole in rock, you will need a drill press, a drill bit, and a vice. Make sure that you select the correct drill bit for your project and the type of rock you are drilling.

Choose the Right Drill Bit

When choosing a drill bit, consider the type and hardness of the rock. For softer rocks like sandstone and limestone, use a carbide-tipped masonry bit. If your rock is harder, such as granite or basalt, use a diamond-tipped masonry bit.

Secure the Rock

Secure the rock to a solid work surface or table using a vice. This will ensure that the rock stays in place while you are drilling. Make sure that the surface is level and that the vice is tight before you begin drilling.

Drilling the Hole

Drilling The Hole

Drilling with a Hand Drill

To begin drilling a hole in rock with a hand drill, you should start by using a masonry bit. The masonry bit should be the appropriate size and length for the type of rock you are drilling into. Place the masonry bit into the chuck of the drill and tighten it securely. Next, ensure the bit is lubricated by adding a small amount of water or oil. This will help keep the bit cool and reduce the risk of it overheating during the drilling process. Once the bit is ready, you can start drilling the hole. To do so, hold the drill firmly and press it against the rock. Start with a slow, steady speed and increase the speed as needed. Once the hole has been drilled to the desired depth, remove the bit from the rock and clean away any debris.

Drilling with a Drill Press

Drilling a hole in rock with a drill press is even easier than drilling with a hand drill. Begin by selecting the correct masonry bit for the type of rock you are drilling into. Place the bit into the drill press and secure it firmly. Make sure the bit is lubricated with either water or oil. Then, set the drill press to the desired depth and speed. Turn the drill press on and press it firmly against the rock. As the bit drills through the rock, be sure to keep it lubricated. Once the desired depth has been reached, turn the drill press off and remove the bit. Clean away any debris and you are done.

Drilling holes in river rocks can be a challenging task, but with the right tools and techniques, it is possible to create beautiful, intricate pieces of art. By following these steps and using the proper safety precautions, you can safely and successfully drill holes in rocks of any size or type.

Drilling Special Cases

Drilling Holes in River Rocks

River rocks are usually soft stones, so it’s easy to drill a hole in them. You will need to use a hammer drill, along with a masonry drill bit that is the same diameter as the hole you want to drill. Start by putting the drill bit in the exact spot you want the hole to be and then hit it with the hammer drill. This should create a small hole, which you can then make bigger with the drill bit.

Drilling Small Holes in Rocks

Drilling small holes in rocks can be more challenging than drilling larger holes. You will need to use a diamond-tipped drill bit, which can create precise holes and will not be damaged by the rock’s hard surface. Start by marking the spot where you want the hole to be and then use a hammer to create a small groove. Place the diamond-tipped drill bit in the groove and slowly start drilling. The diamond-tipped drill bit will create a clean, precise hole.

Finishing the Hole

Cleaning the Edges

Once the hole is successfully drilled, use a brush to remove all the dust and debris. It is important to clean the edges of the hole so that the sealant can stick properly.

Applying a Sealant

Once the edges of the hole are clean, apply a waterproof sealant to the area. This will ensure that the hole stays sealed and any moisture or water is kept from entering into the rock. Allow it to dry completely before using the hole.


Drilling a hole in rock is not as difficult as it may seem. With the right tools, materials, and know-how, you can easily make a hole in any type of rock.

  • Gather the necessary materials, such as a drill bit, hammer, and chisel.
  • Create a starter hole using a hammer and chisel.
  • Secure the drill bit into the drill.
  • Slowly drill the hole with the drill bit.
  • Remove the drill bit and clean the hole.

If done correctly, you will have a neat and clean hole in the rock that can be used for whatever purpose you need.

Frequently Asked Questions

What kind of safety gear should I wear when drilling a hole in rock?

Protective eyewear should be worn at all times when drilling a hole in rock, as flying debris can cause serious injury.
Hearing protection is also necessary to protect your ears from loud drilling.
Safety gloves should be worn to protect hands from sharp objects and flying material.
Dust mask is recommended when drilling larger holes as the dust can be hazardous to inhale.

  • Safety glasses or goggles
  • Ear plugs or ear muffs
  • Non-slip work gloves or welding gloves
  • Dust mask or respirator

Additionally, it is important to ensure that the drill bit is properly secured to the drill before starting the drilling process.

What type of drill bit is best for drilling a hole in rock?

For drilling holes in rock, a carbide-tipped masonry bit is the best choice. These bits are specially designed for drilling through hard materials like stone, brick, and concrete. Masonry bits are made with a hardened steel tip and sharp edges, which help to cut through the rock more easily. Additionally, these bits tend to be more durable than other types of drill bits, so they will last longer.

What should I do if the drill bit gets stuck in the rock?

If the drill bit gets stuck in the rock, stop drilling immediately and use a hammer to try and loosen the bit. If it is still stuck, slowly apply some penetrating oil to the bit and wait five minutes before trying to remove it again. If it still won’t budge, you may need to use a drill bit extractor to remove the bit.

How do I make sure I’m drilling the hole in the right spot?

  • Mark the Spot: Mark the spot where you want to drill the hole. Use a pencil, marker, or other marking tool. Make sure the spot is visible and easy to access.
  • Check the Location: Make sure the spot is in the right location. Look at the area around the spot and make sure it is safe to drill in that spot.
  • Measure the Spot: Measure the spot with a tape measure. Make sure the spot is the right size and depth for the hole you want to drill.
  • Check the Depth: Check to make sure the hole is not too deep. Make sure the hole is not deeper than the thickness of the material you are drilling into.
  • Double-Check: Double-check the spot before drilling. Make sure the spot is the right size, location, and depth for the hole.

How Deep Should I Drill the Hole in the Rock?

  • Check the Depth Requirements: It is important to check the depth requirements of the project before you begin drilling. The depth of the hole will depend on the size and type of rock, as well as the purpose of the hole.
  • Mark the Spot: Once you have determined the depth of the hole, mark the spot where you will be drilling. This will help you to keep the drill in the right spot and at the right depth.
  • Drill Slowly: Begin drilling slowly. Drilling too quickly can cause the drill bit to overheat, which can cause damage to the rock. It can also cause the drill bit to break.
  • Measure the Depth: Measure the depth of the hole as you drill. This will ensure that you are drilling to the desired depth and that you are not drilling too deep.
  • Stop Drilling: Once you have reached the desired depth, stop drilling and remove the drill bit. Wipe the area clean and inspect the hole to make sure it meets the requirements of the project.


Drilling a hole in a rock is a difficult process that requires patience and knowledge of the right techniques and tools. With the right equipment, an understanding of the process, and a steady hand, anyone can drill a successful hole in a rock.
