It’s possible to utilize a variety of drill bits while working with granite. There are pros and downsides to each one. What is the best drill bit for rock? That’s the question we’ll answer in this piece.

Drilling through rock is sometimes necessary for a variety of reasons. Drilling into such tough rock needs a lot of strength and force. It’s also feasible that this activity may appear tough or laborious if you don’t have the right tools.

You might also destroy the rock and your project using an incorrect drill bit. Therefore, before beginning any project that entails drilling holes into a rock, it is essential to know which type of drill bit is appropriate for the job.

What Should You Consider Before Buying a Drill for Rock?

First, you must select what type of drill bits you need before you can buy any rock drilling bits at random. This will assist in selecting the appropriate drill bit. Let’s take a look at some of the things to keep in mind.

Building Material:

The material will determine how long the drill bits last and their effectiveness at their job.

You should consider using hardened or carbide steel bits to drill hard materials since they can sustain high temperatures and heat. To get the most out of your labor, use carbide bits.

Drill Bit Types:

A variety of drill bits are available, each with a unique design.

As we move further, we’ll look at SDS and diamond-tipped drill bits. Make a hammer drill by inserting an SDS drive system into the chuck.

Diamond drill bits make the accurate core hole in hard material. Hard materials are no match for these drill bits, which are the finest on the market. You can choose one or more of them, depending on your needs.

Size of Drill Bit:

Drill bit sizes are a crucial consideration. Check the sizes of all the drill bits in a set before buying them if you plan to use them.

The size of the drill bit determines the size of the hole you wish to make. Drill bits can be as little as 1/32-inch or as large as 3/4-inch in diameter; the greater the size range, the better. Always choose a drill bit kit with many different drill bit sizes to avoid later frustration.

The number of Drill Bits:

It’s possible to buy a set of drill bits that includes numerous bits. These sets are ideal for various applications since they may be used to drill holes of varying diameters. Some drill bit sets have six bits, while others include ten, twelve, or even twenty. Pick a good drill bit set that has a larger number of bits.

Geometry

Each bit’s helix shape should be considered when doing your analysis. However, it will take longer to insert the tighter rings since they are more difficult to remove. The number of cutting surfaces of a drill bit should also be considered. A bit may remove more material from the substrate when it has more cutting heads.

Hammer drill

Several drills utilize the hammer drill mechanism for drilling into stone. In this case, it’s about how the drill is used.

If you’re drilling into hard materials, this may be useful since it permits you to pulverize the stone before you try to remove it. To use a hammer drill for rock, you should seek a bit made expressly for that purpose. It will have a more compact design and be better equipped to withstand shock.

Guarantee:

Most drill bits don’t come with a guarantee, but there are manufacturers that provide a 1+ year replacement warranty. Consider purchasing drill bits with a guarantee so you may use them for an extended period.

Accessories:

A storage container for the drill bits would greatly assist while traveling with them. Look for a drill bit with a sturdy case that you can securely store the bits in.

Tips for Choosing and Using the Best Concrete Drill Bits

There are several things to remember while selecting and utilizing a masonry drill bit to guarantee a good end.

  • Only purchase tools with tungsten carbide tips. Only tungsten carbide is tough enough to withstand grinding away at the stone with an abrasive. Except for whole saws, all masonry bits should be tungsten carbide. Using a diamond-coated whole saw is recommended for drilling bigger holes.
  • Make sure the software will run on your computer. Choose a bit with a shank that is compatible with the drilling equipment you want to use. SDS+ bits can only be used with rotating hammer drills, while hex bits can only be used with regular drill chucks.
  • If you’re going to do something, do it as a group. You may save a lot of money by getting a set of four, five, or even more masonry bit sets rather than purchasing individual bits.
  • A pilot hole should be drilled initially. Drill a shallow pilot hole with a smaller bit before switching to a 12-inch masonry bit. Allows the big bit to stay on the workpiece without sliding.
  • Stop frequently to clear the way. When drilling a hole, a clean home is essential because debris might jam the drill and slow down the drill bit. Stop and blow the dirt out of the hole from time to time.

Reviews 

The consumer said a 3/4-inch drill bit was the only reason to buy this kit. A 3/4-inch SDS-plus drill bit in local hardware stores will put back more than what I paid for this set. To install the new water park safety cover, had to drill 15 2-inch holes in the stone. The new hammer drill could handle a 3/4-inch drill bit easily. It just took ten seconds to drill a 2-inch hole.

In my opinion, this drill bit set is well worth the price. However, to utilize the rest of the set’s drill bits is something anticipating. In a small plastic box, this drill bit box was delivered. A drill bit with a 3/4-inch shank survived well after 15 holes were drilled in the concrete.

FAQs

What kind of bit can drill through rock?

Put in an appropriate masonry drill bit with a carbide or diamond end. For this, you’ll need to loosen your drill’s chuck before putting the end of your bit and then retightening it. Avoid using a wood bit to drill into rock since doing so may result in the bit shattering, which can cause significant harm.

However, there’s a downside to having only one layer of fake diamonds. PDC bits may drill through moderate to hard rocky outcrops, including salt, sandstone, and clay.

Should I use water when drilling rocks?

This method keeps everything cold while drilling: drill bits and rock. Diamond-tipped bits will last longer if you do this. As a result, the rock that you’re drilling holes into will not break due to the expansion of the heat.

Conclusion 

Even if drilling hard stones is difficult, it may be made simpler using a strong, long-lasting, and effective drill bit. Consider how much heat the drill bit creates and how long it can be utilized for before making a purchase.

It’s a great set of drill bits since they’re solid, sturdy, and speedy. There are a variety of uses for the eight different bit sizes. There isn’t a drill bit on this list that won’t work well with hard stone.
