How to Cut Rocks?

Rock is the most compact, and abrasive substance found anywhere in the universe. To slice through them, you will want a sharp and strong saw. Using a tile saw to cut rocks is the method I will always suggest. 

Traditional rock-cutting saws are not only expensive but also lack the accuracy necessary to cut through rocks successfully. Your best chance is to invest in a tile saw with a blade tipped with diamond. On the other hand, your success rate is directly proportional to the amount of work you put into the preparation. 

You will be required to successfully carry out a series of actions to cut and shape rock to your preferences. I’m going to walk you through the process of using a tile saw to cut rocks in this article.

Evaluation of the Roughness of the Rock:

Every substance possesses its own particular set of qualities and capabilities. The molecular density and the hardness level of rock allow it to withstand significant amounts of force. The mineral components can identify several distinct types of rocks, and all of these rocks have varying degrees of abrasion resistance.

The level of a rock’s hardness may often be determined using the Mohs scale. If you want to cut and shape a stone, you must know its hardness and associated features. This knowledge will assist you in selecting the appropriate tools and blades to slice through them with ease. 

On the Mohs scale, the mineral talc has a hardness level that is the lowest possible. It is only one. The next mineral on the list is gypsum, which has a Mohs hardness rating of two and is the second-lowest mineral on the scale. 

Calcite, which has a level three of hardness, is the mineral that comes in third place on this list. Fluorite has a hardness rating of four, placing it in the fourth position overall. The fifth mineral on the list is called apatite, and it has a hardness level of five. 

The sixth mineral on the list is called orthoclase, and it has a hardness level of six. If you are dealing with the minerals that have been stated, then it should not be difficult to cut. On the Mohs hardness scale, rocks with a hardness level ranging from 1 to 6 are considered the more pliable and simple to work with.

Topaz is an even harder stone than quartz, which only registers a seven on the Mohs scale. Diamond has a hardness rating of 10, significantly higher than corundum, which only has a nine. 

On the Mohs scale, minerals with a hardness level between 7 and 10 are considered the hardest found. Cutting through these minerals is going to be a bit challenging.

It would help if you now had a good sense of the rocks and the degree to which they are hard at this stage. Now would be a good moment to select the appropriate saw. Choosing the appropriate instrument is necessary to achieve the desired level of success. 

We are working with a rock, the most compact and abrasive substance found anywhere in the universe. To accomplish the task at hand, it goes without saying that you will want the most effective instrument. Using a tile saw to cut rocks is the method I will always suggest.

Traditional rock cutting saws may be purchased, but they are extremely pricey, and they lack the power and precision necessary to cut through any hard material. 

Most of their functionality is centered on slabbing off a tiny rock section. Your best chance is to invest in a tile saw with a blade tipped with diamond. 

It may seem strange to you how a little tile saw can cut through very heavy and solid rocks, but rest assured that it can easily cut through boulders that are four inches thick. In addition, you may rapidly cut squares that are six inches by six inches. 

Compared to the cost of a tile saw, the cost of a rock saw can almost reach a thousand dollars, but the tile saw is far more affordable. Tile saws are far superior to their more conventional counterparts, the rock-cutting saws, in my opinion.


Choosing the Appropriate Blade:

To cut rock effectively, I suggest using a continuous diamond blade. You will get a cut that is efficient and precise as a result. In addition, a continuous blade features diamond rims rather than ridges along its edge. You won’t have trouble slicing through even the hardest rocks with this blade, renowned for its precision.

I can guarantee that the use of this blade will not result in the fragmentation of your rock sculpture. The main negative associated with these blades is that they will wear out rather rapidly and can slice through tough boulders. It is my recommendation that you make use of this blade while cutting slabs or delicate stones.


The Easiest, Most Effective Way to Cut Rocks: Step-by-Step Instructions

You are now prepared to start the cutting procedure after incorporating a tile saw into your collection of tools and fitting it with the most suitable diamond blade.

Safety First:

Before utilizing any power equipment, I insist that suitable protective gear be worn. Therefore, you should safeguard yourself by using dust protection masks, eye protection, ear muffs, thick clothes, and safety gloves.

Try cutting rocks with a wet saw rather than a dry one to prevent the problem of the saw overheating. Before beginning the cut, ensure that the saw is properly set up, the wire is in good condition, and the sharp blade is. 

Try not to get frustrated since putting on all safety equipment will only take a few minutes of your time. A modicum of caution on your part is going to assist you in avoiding situations that might endanger your life.

Putting the Stone in Place:

Putting the rock in place is the next step. Please make an effort to line the stone with the blade and position the stone so that it is resting on a stable edge. Try applying duck tape to the jagged edge; it will provide more stability as you cut and prevent stone fragments from splintering.

It is possible to use wooden blocks to support the stone and stop it from sliding around while cutting it. Try moving the rock towards the blade rather than pushing it closer to the edge. 

If you could stand on the other side of the rock, it would make pulling considerably simpler. Put on a plastic coat and gloves if you use a wet blade since this will prevent you from becoming wet.

The Beginning of the Process of Cutting:

While you are dragging the rock, make an effort to maintain a consistent movement and a somewhat soft grip. If you apply an excessive amount of force to the rock pulling or pushing motion, there is a greater possibility that the rock may fracture. 

Make an effort to exert a little force. If you see that the blade is not cutting properly, you should immediately halt the cutting process and examine the degree to which the blade has been sharpened. The blade will likely get dull if you use excessive force on the saw.

Be sure to check the amount of water in the saw’s reservoir regularly if you want to cut rocks with a wet saw. It would help if you made every effort to store some more water in a bucket close to you. If you see that the water level is decreasing, you should add some water so that the bucket remains full.

Keep an eye on the stone’s surface, whether you are pulling or pushing the rock (although I would advise you to pull it). If there is excessive redness or sparks of fire on the stone’s surface, you should break and allow the stone to cool down for a while.

This will make it much easier for you to accomplish it, and it will also lessen the likelihood of the rock shattering in your hands.

Grinding the Rock:

You might try using an angle grinder to hone down the jagged edges. It may also be used to polish the surface, giving it a brighter and more attractive appearance.


When Using a Tile Saw to Cut Rocks, There Are a Few Important Things to Consider:

It would help if you stuck to a few important guidelines to achieve your goals effectively. You will find some data presented down below for your perusal.

  • When cutting rocks, you should use blades that have diamond tips. It is the most suitable option for the position.
  • Repeatedly checking the saw’s water chamber will save you from having to halt the cutting process.
  • When the blade is in motion, it is important to keep your body parts at a safe distance from it.
  • Place the safety supplies in the appropriate locations.
  • To achieve an accurate cut, you need to mark the rocks.
  • Hold your breath until the blade reaches its maximum speed.
  • Take it easy as you’re pulling the rocks. In that case, there is a chance that the blade will become damaged.
  • Before making the next cut, ensure the tile saw is turned off.

Frequently Asked Questions:

Can I grind with a tile blade?

You may use these to tidy up preform edges before going to the correct tool. It’s not good for heavy grinding, and pushing too hard on the blade might deform it.

When cutting pebbles, should I grease my tile saw?

Although a tile saw will absorb oil, it is not required. It’s also a bad idea. Oil and dust will be sprayed everywhere, necessitating a significantly larger clean-up. It’s overkill for most tile saws, but care to drain the bottom water.

What may go through the hard surface of a rock?

Carbide-tipped chisels are more effective at cutting softer rocks than steel chisels; hence, steel chisels can be used to cut harder rocks.


Bottom Line:

Although picking the appropriate tool to cut rocks is essential, one can almost always locate the most suited instrument for the task. While a tile saw may be used to cut rocks and masonry, a diamond blade is better suited for cutting ferrous and nonferrous metals in addition to concrete.
