How to Drill into the Rock- The Amazing and Perfect Guide

Learning about architecture might be thrilling, but when you’re working on a project and encountering an issue, you can’t easily address, like drilling, the true challenge begins. This article will show you How to Drill into the Rock.

It’s possible to have a smooth drilling procedure through a concrete barrier if you know how to handle stones and rocks, but your drill bit might be ruined if you don’t know how to handle them.

You must realize that drilling through rocks is one of the most difficult tasks you’ll face when working on a construction project.

What would you do if you had to drill through a rock? To do this activity independently, you don’t need an expert mason. We’ve laid out the five stages you have to follow here.

What’s Wrong with Drilling into Rock?

Due to the difficulty of working with hard stones and boulders when drilling, a solid concrete drill that runs smoothly might be a serious challenge.

If you do not even know how to handle them, your drill bit might be in trouble. Drilling into it is one of the most difficult materials to work with.

Remember These Things When Drill into Rock

When drilling holes in the rock, a few procedures are the same regardless of the type of instrument utilized. So that they aren’t repeated, I’ve decided to put them in writing. You’ll thank me when you see the outcomes.

Using Water as a Medium

You’ll notice in the next stages that I recommend using shallow buckets to hold water. During the drilling process, I use these containers to submerge the rock, and the shallow sides provide for easily accessible for my hands without requiring uncomfortable angles.

During the cooling process, water is utilized as a coolant for the drill bit and the rock. Regular cleaning and lubrication of diamond-tipped bits extends their useful life. Additionally, it will keep the rock you’re drilling holes in from shattering because of thermal expansion.

One centimeter is a good distance from the surface of the water where I operate. Thus, I can continue drilling without worrying about damaging the drill chuck or tip by keeping them out of the water.

If you’re utilizing an electric rotary tool, pay attention to this. Unfortunately, electricity and water don’t mix well. Therefore it’s worth saying the obvious. Ensure your electric-powered equipment isn’t in contact with water at all times.

The Selection of Drill Bits

When drilling holes in the rock, the kind and depth of the hole dictate the type of drill bit used. To drill tiny holes, it is recommended that you utilize a tungsten carbide masonry bit.

To utilize diamond core bits to drill larger holes, you will need to drill all the way through the material, which will leave you with a core to remove.

Drill Bits for Masonry

The most popular way to utilize masonry drill bits is using a hammer drill, which rotates the bit while striking it into the rock. The bit tip is hammered into the rock to fracture it, and the rock is then brushed off with revolving flutes.

Each hammering motion pushes the cutting blades of the drill bit to a new area of the whole bottom.

Form of a Hammer

For hammer drill bits to travel easily within the chuck when hammering, they feature unique shank shapes To drill large holes in rocks, core bits can be utilised to use.

Using hand-held power tools and masonry bits up to 39 inches long, effective rock drilling may be achieved with minimal risk to the operator.

Star Drill bits, which resemble chisels or punches, are drilled into the stone using hand-powered drills and hammers. The star-shaped cutting edge of a star drill bit is made up of many blades that have been glued together in the center.

Drilling Bits from Diamond

Diamond drill bits are typically utilized when drilling into granite, limestone, or marble. Diamond drill bits are the best because they are made of diamonds and have highly sharp tips that are excellent at cutting through hard rock.

When using diamond drill bits, slow down and lubricate the drill bit with a lot of water to get the best results.

Different kinds of Diamond Drill Bits

Diamond drill bits can be divided into two types based on the purpose for which they are intended.

  • Drill bits that are bonded to the chuck
  • Drill bits are made of sintered metal.

Diamond drill bits exist in various forms and sizes, but the two most common varieties are hollow and solid.

5 Easy Steps on How to Drill into the Rock

Step# 1

It is important to consider a few factors before you begin the primary drilling procedure, one of which is the rock size.

If you’re working with huge boulders and need to be able to move them around easily, a cordless hammer drill is your best bet. Of course, it’s possible to get by with a corded hammer drill, but having a cordless drill would provide you with more mobility.

When drilling into a rock, you should also consider the size and number of holes you want to make. To drill a precise hole, use a pencil to indicate where you wish to drill.

The rock size will dictate your drilling strategy, but you may use modeling clay to stabilize the stone and prevent the drill bit from biting through your work surface.

The smallest rocks can be drilled by placing them in a jar with some clay on the bottom.

Step# 2

Use a fully charged cordless hammer drill whenever feasible.

Because rock is a hard substance, you’ll need a lot of power, so make sure your tool has a fresh battery in it if it doesn’t have enough.

To operate on a massive immovable rock, you can use an extension corded hammer drill to quickly get the power to the desired position.

Additionally, you’ll need a small plastic container, molding clay, water, safety glasses, a dust mask, and the rocks you’ll be working on.

Step# 3

After assessing the hole size and the type of bit that best suits the task at hand, choosing a drill bit is the next step.

Any rock drilling would necessitate the use of a masonry carbide or drill bit. Installing your bit is as simple as releasing the drill chuck, inserting the bit end, and then tightening the chuck again.

If you don’t shut the chuck correctly, you risk causing an accident during the work process. Likewise, drilling into a rock with anything other than a wood bit might result in severe damage.

Step# 4

Knowing how to use the correct tool is only half the fight won. In order to utilize diamond core bits to drill larger holes, you will need to drill all the way through the material, which will leave you with a core to remove. As we’ve already said, a pencil or marker is the finest way to map your drill’s path in your rock.

To begin, set the drill bit exactly where it was indicated on the rock and carefully drop its tip down to establish a 90 percent angle as if you were slicing through the rock simultaneously.

Using a work surface to drill into tiny rocks, you should keep your drill bit in a stable vertical position.

Step # 5

Before drilling, put on a dust mask and safety goggles and pull the trigger on your drill. It’s best to begin with, a gentle up-and-down motion and gradually increase the pressure as you go.

To get a good finish, keep the bit straight in the rock while drilling until you reach the appropriate depth, and then withdraw the bit from the rock. Drilling may be done in the same way for each of the previously designated areas.

Make sure your rocks are immersed by placing them in a plastic tub with clay at the bottom. The water is used to do both to keep the rock clean and a bit cold. Let’s get started! Your rock may be cleaned and dried when the process is done.


Can You Drill Screws into Rock?

The hammer drill can make a pilot hole in the rock. Avoid drilling the drill string or screwing in the screw too close to the stone’s edge to avoid chipping or cracking the stone. The masonry screw’s length should be about 14 inches longer than the height of the small hole. Make one pilot hole for each masonry screw.

How Do You Drill Through Natural Stone?

It is advised that the drill bit be placed at a 90-degree angle with speed progressively increased as it penetrates the stone to minimize chipping or to split it. The aim is to change the bit with bigger diameter and gradually increase through the measurements as necessary.


Drilling into rock may be easier by following these procedures, but a drill-driven stone may still break even with this pressure. Supplementary instruction is available for those who need to drill through concrete.

The interior fracture lines in some stones can be broken apart by extreme pressure. Thus, you need to determine whether or not to take the risk with the stone at the outset.
