Can I Cut a Quartz Countertop?

What is Quartz?

Before discussing how to cut quartz, it’s important to understand what it is. Quartz countertops are made from ground natural quartz crystals combined with resins and pigments. The result is an engineered stone that is non-porous, stain-resistant, and heat-tolerant.

While granite and marble are mined directly from the earth, quartz slabs are fabricated in factories under precise conditions. This allows quartz to have consistent coloring and patterning without natural flaws found in natural stone. The resins make quartz more flexible and resistant to cracks and chips.

Can You Cut a Quartz Countertop?

The short answer is yes, you can cut a quartz countertop yourself if you have the right tools and techniques. However, quartz is difficult to cut cleanly without chipping due to its engineered composition. Professional fabrication with specialized tools is ideal for any major modifications.

Small trims such as rounding the corners or cutting holes for sinks can potentially be DIY projects if great care is taken. Attempting extensive quartz cutting as an amateur could lead to unattractive results and damage to the material.

How to Cut Quartz Countertops

Cutting quartz countertops requires patience and precision. Here are some tips to follow:

Use a Diamond-Blade Wet Saw

The only way to accurately cut quartz stone is with a professional-grade wet saw designed for stone. A diamond-coated blade and water-cooling system is required to minimize friction and overheating. Rushing the cut or using a saw without water increases the risk of fracturing the quartz.

Mark Guidelines Carefully

Use a straight edge and permanent marker to draw an accurate cut line. Measure twice to avoid expensive mistakes. The line serves as a visual guide as you cut.

Cut Very Slowly

Make the cut in gradual, smooth passes without forcing the saw. Apply minimal pressure and let the diamond blade do the work. Going too fast can overheat and crack the slab.

Support the Cutout Section

Have a helper hold and support the cutout piece as you cut to prevent cracking under its own weight.

Smooth Edges

Use a diamond polishing pad or fine-grit sandpaper to remove any small chips on cut edges. Be gentle and don’t polish aggressively.

Clean Up Residue

Once cut, wash the countertop with plain water and a soft cloth to remove any dried slurry or residue from the sawing process.

FAQs About Cutting Quartz Countertops

Can I cut quartz countertops with a circular saw?

No, a normal circular saw cannot provide the smooth, precise cut needed. You will get the best results using a specialized diamond wet saw.

What safety gear should I use?

Wear safety goggles, ear protection, gloves, and a mask to protect from dust. Make sure to keep hands away from the blade during cuts.

How thick are quartz countertops?

Quartz slabs are typically available in thicknesses between 2 and 3 cm. Thinner quartz is more delicate and prone to damage from cutting.

Can I cut quartz myself with a wet saw?

It’s possible for a DIYer to rent a wet saw and cut their own quartz with proper caution. However, the difficulty of achieving clean cuts may outweigh the cost savings of doing it yourself.

Does Home Depot cut quartz countertops?

Most Home Depot locations do not offer quartz cutting services. You would need to find a specialized stone fabrication and installation company.

What happens if I crack my quartz countertop while cutting?

Cracks or chips are hard to repair seamlessly. You may need to replace the entire damaged section, which can get costly. It’s best to leave major cuts to the professionals.


Cutting quartz countertops is a challenging task due to the nature of the engineered stone. While small, simple cuts can potentially be done DIY with a diamond wet saw, it’s safest to rely on professional fabrication shops for more complex jobs. Their specialized tools and expertise give the best results and minimize the risks of permanent damage. Be sure to carefully measure and mark all cuts to be made for the most accurate outcome. With patience and care, quartz countertops can be modified to fit your unique space.
