Cutting Bricks – 2 Steps You Should Take for Cutting Bricks Like a Professional

The advent of cutting bricks marked one of the revolutionary discoveries across the globe. Ever since its inception till date, bricks have remained the go-to and foremost building and construction material. Also, its strength and resistance to degradation or wear make it a number one choice. 

Despite their superior qualities, bricks are brittle, especially when not properly cured. Hence, you must pay extra care to cut bricks to avoid breakage and wastage. 

This article details the intricacies of cutting bricks and exposes some useful tips and tricks.  

Section 1: Which tools are appropriate?

The tools needed for cutting bricks would always vary based on the method used. Before now, a masonry chisel would perfectly cut bricks, although it is always tasking. And at least a 3/4 inch wide chisel would do the job well. 

Also, a brick hammer is great for cutting bricks. Nonetheless, if you want to use a bladed-brick chisel,  make sure it’s at least 3 inches wide. On the other hand, the downside to using hand tools is that they have poor precision. Consequently, it is safe to conclude that hand tools are easier to operate, flexible, and inexpensive.

However, the advent of power saws brought an end to poor accuracy and precision in cutting bricks. Nowadays, you can precisely cut bricks without the fear of committing a measurement error. In fact, these power saws could range from miter saws to angle grinders. Whether it’s the hand tool or power saw, you need to measure and mark out the region to cut.

In general, ensure you wear the appropriate safety gear such as goggles, a nose mask, and maybe a hand glove. The dust generated from cutting bricks is harmful to internal organs such as the lungs.

Section 2: How to cut bricks?

In this section, we describe cutting bricks with the use of both hand and power tool. Below are the steps to follow in chronological order:

2.1 Prepare tools

Ensure that you have the tools mentioned below ready to use and in good working condition. The tools you need will eventually depend on which approach you intend to use.

Angle grinder or Circular saw.

Pencil/Marker

Measuring tape

diamond masonry blade

Hammer

Chisel

Dust Mask

Square

Safety goggle

Workbench

Gloves

2.2 Cutting bricks with a circular saw or angle grinder.

2.2.1 Draw a cutline.

With the pencil or marker, measuring tape, and square, measure and carefully draw the cutting line. This line will eliminate any possibility of making mistakes when you eventually start cutting, as it will guide you.

2.2.2 Attach a diamond masonry blade.

Since you are using an angle grinder or circular saw, then you must mount the blade. However, in this case, the blade is a diamond masonry blade installed using a wrench. Loosen the arbor nut or bolt and correctly place the blade with its teeth opposite the cutting direction. Lastly, tighten the bolt or nut as the case may be.

2.2.3 Test power tools.

Once you correctly mount the blade, you can plug in the saw or grinder to test run. The initial test run is to ascertain that the blade is balanced and will not wobble on the arbor. Now you can go for the cut.

 2.2.4 Cut the brick.

Remember that you have initially used a marker to mark-out the brick’s surface and bottom; now proceed to cut. Gradually progress into the brick, do not rush the process while allowing the blade to do the work. Start by cutting ½ inch deep; you can do this by setting the blade depth on the saw to ½ inch. But if it’s an angle grinder, use your discretion to figure out the initial depth to score the brick. Nevertheless, to avoid overheating, remove the blade from the brick every 30 seconds. The cutting depth into the brick largely depends on the brick’s thickness and the blade’s diameter.

 2.2.5 Strike.

Place the already scored brick in a cantilever position and strike with a hammer. The unwanted part of the brick should fall off, and you can have your preferred brick size left. 

2.3 Cutting bricks with a chisel.

 2.3.1 Draw a cutline.

With a pencil or marker, accurately draw the cutline around the four sides of the brick. 

2.3.2 Score along the cutlines.

Use a chisel placed at about 60 degrees to create initial grooves around the four-sided cutline. This groove should be about 1/16 inch deep.

2.3.3 Hammer along the groove.

Place a chisel along the scored cutline and firmly hammer. With a few precise hammerings, the unwanted part should come off.

2.3.4 Remove uneven and excess pieces of brick.

The wanted piece of brick may carry some excess brick along the freshly cut surface, chip them off. Either a chisel or stone carving file will perfectly do this job.

Section 3: Which is the best way to cut bricks?

Undoubtedly, the diamond saw blade is the best way to cut bricks, especially when precision is in dire need. Thus, this approach produces a clean cut without excess or uneven surface and edge. In addition, this approach requires no need for continuous hammering and stress that arises from chisel and hammer use. Therefore, only a saw blade or angle grinder will do the job efficiently and accurately for large projects.
