How to Cut Granite Countertops: The 7 Steps

Granite is one of the most popular building materials for bathroom and kitchen renovation projects. The natural stone’s functional benefits and beauty make it the perfect choice to utilise within the home. Whether you opt for a professional to do the job, or you’re going down the DIY route, there’s no denying that home renovation projects can be costly.

If you would like to save money on the project, you can put your gloves on and cut granite countertops yourself. However, you’ll need to know exactly what steps to take to stay safe, do a good job, and be left with the desired result. With that said, here are 7 steps to follow on how to cut granite countertops.

  1. Put On Safety Gear

Before getting to work cutting granite countertops, you need to ensure you’ve got safety gear on. This includes goggles, a dust mask, and earplugs. Health and safety should be your top priority, otherwise, you run the risk of getting injured while performing the job. 

  1. Set Up Your Workspace

Once your safety gear is on, setting up your workspace is next. Move the granite onto your workspace and ensure you’ve got the right cutting tools ready and raring to go. Check out Amastone who sells the best granite cutting tools. They have guides on such products to help you find the right ones for the job.

  1. Measure the Area You Wish to Cut

Next, grab a tape measure or ruler to confirm the area that you’ll want to cut. This must be very precise, so attention to detail is essential. There is no going back should you cut corners and make a mistake. 

  1. Apply Painter’s Tape

Once you’ve measured exactly where to cut, next you need to apply a strip of painter’s tape to where you’ll be cutting. After doing this, draw a straight line on the top. This line is crucial as it serves as a visual aid while you cut.

  1. Prepare the Saw and Start Cutting the Granite

Make sure to prepare the saw you will be using for the job. Regardless of whether it’s a dry or wet saw, it must have a diamond blade. If you opt for a weaker blade, this won’t be able to properly cut through the granite slab.

  1. Spray Water on Granite and Keep a Close Eye

Have someone with you spray water on the granite while cutting. This needs to be done due to the heat and pressure caused by cutting granite. Also, make sure to keep your eyes on the saw at all times. Doing so will keep your safety in check.

  1. Check Your Cut and Polish the Granite

Once you’ve completed the cut, look to make sure the cut is satisfactory. Once you’re satisfied, you can either finish the job or move on to your next cut. If you’re ready to finish, use an angle grinder equipped with a diamond grinding wheel so shape and smooth edges to get your achieved look. 


While we always recommend that you hire a professional to install granite countertops, you can make cuts as and where you would like yourself. Just make sure to follow the steps above to perform the role correctly and stay safe.
