A wet or dry circular saw or angle grinder fitted with a diamond blade designed for granite. Wet saws are preferred because water cools the blade and reduces dust.

Ear Plugs

Stone cutting is very loud.

Gloves

Protect your hands from sharp edges.

Step-by-Step: How to Cut Granite

Step 1: Measure and Mark

Measure carefully, apply painter's tape along the cut line and mark it clearly.

Step 2: Support the Granite

Place the granite on a flat, stable surface with support on both sides of the cut so the offcut does not snap and chip the edge.

Step 3: Set Up Water

Connect water to the saw or have a helper spray water on the blade.

Step 4: Score the Line

Make a shallow first pass along the line to guide the blade.

Step 5: Cut Gradually

Make several passes, increasing depth each time. Do not force the saw — let the diamond blade do the work.

Step 6: Finish the Cut

Slow down near the end to prevent breakage.

Step 7: Smooth the Edge

Use diamond hand pads from coarse to fine grit to smooth and polish the cut edge.

Safety First

Always cut outdoors or in a well-ventilated area
Prefer wet cutting to suppress dust
Keep hands away from the blade
Disconnect power when changing blades
