Equipment, Blade Types, and Professional Cutting Tips
Granite is one of the hardest and most durable natural stones used in construction. To cut granite cleanly and safely, you need a diamond blade designed specifically for granite.
Equipment for Cutting Granite
1. Tile Saw (Wet Saw)
Many professional tile saws can handle granite up to 20–30 mm thick (3/4"–1-1/4"). Water cooling is mandatory. Many professionals use a pendulum method, cutting in passes of 3–5 mm per pass.
2. Stone-Cutting Machine (Masonry Saw)
Dedicated equipment for processing natural stone. Typical blade sizes: 300–400 mm (12"–16"). Cutting capacity up to 70 mm (2-3/4") thick.
3. Angle Grinder
A versatile and portable option for dry cutting. Common blade sizes: 125 mm (5") and 230 mm (9"). Maximum cutting depth up to 70 mm (2-3/4") with a 9" blade.
Types of Diamond Blades for Granite

Continuous Rim (Crown)
Wet cutting only. Cleanest edge finish, minimal chipping. Best for finish work, cladding, countertops, and visible edges.
Turbo Rim
Wet or dry cutting. Faster than continuous rim. A strong all-around option for most granite jobs.
Segmented Rim
Excellent cooling, high cutting speed, rougher edge. Best for rough cutting and heavy-duty work.
Key Factors When Choosing a Granite Blade
Check Maximum RPM Rating
Using a blade above its rated speed can cause accelerated wear, diamond layer failure, blade breakage, and serious injury.
Wet vs Dry Operation
Wet cutting reduces friction, cools the blade, extends blade life 2–3×, produces cleaner edges, and reduces dust exposure. Strongly recommended for premium granite work.
Correct Blade Size for Equipment
- Tile saw: 7"–10" (180–250 mm)
- Masonry saw: 12"–16" (300–400 mm)
- Angle grinder: 5" or 9" (125 or 230 mm)
Practical Tips for Cutting Granite
- Multiple shallow passes are better than one aggressive pass
- For thick granite, cut in 5–10 mm increments
- Use water whenever possible
- Take 20–30 second cooling breaks during dry cutting
- Use continuous or turbo blades for finish cuts
- Start cutting from the finished (face) side
Conclusion
For clean, precise cuts: use continuous or turbo blades, prefer wet cutting, and cut in controlled passes. For heavy production and rough cuts: use segmented blades.
