Can I use a cut off wheel for stone on sandstone? That's a question I get asked a lot as a supplier of cut off wheels for stone. And the answer is, well, it depends. In this blog, I'll break down the factors you need to consider and give you the low - down on using cut off wheels for sandstone.
What is Sandstone?
First things first, let's talk about sandstone. Sandstone is a sedimentary rock made up of sand - sized grains of mineral, rock, or organic material. It's porous, which means it can absorb water and other liquids. Its hardness can vary quite a bit, from relatively soft to moderately hard, depending on the type of cementing material that holds the sand grains together.
How Cut Off Wheels Work
Cut off wheels are thin, circular discs with abrasive particles on their surface. When you use a cut off wheel, the wheel spins at a high speed on a grinder or a cutting tool. As the wheel touches the material you're cutting, the abrasive particles grind away at the surface, gradually cutting through it.
Compatibility of Cut Off Wheels with Sandstone
Abrasive Type
The type of abrasive on the cut off wheel is crucial. For sandstone, you'll want an abrasive that's hard enough to cut through the rock but not so hard that it causes excessive chipping. Aluminum oxide is a common choice. It's relatively hard and can handle the job of cutting through sandstone without too much trouble. Silicon carbide is another option, especially for softer sandstones. It's a bit more brittle than aluminum oxide but can provide a smoother cut.
Bonding Material
The bonding material holds the abrasive particles together on the wheel. For sandstone cutting, a resin - bonded cut off wheel is often a good choice. Resin bonds are flexible, which helps to reduce the risk of the wheel cracking or breaking when cutting through the porous sandstone. They also dissipate heat well, which is important because cutting generates a lot of heat, and too much heat can damage both the wheel and the sandstone.
Advantages of Using Cut Off Wheels on Sandstone
Precision Cutting
Cut off wheels can make very precise cuts. Whether you're making straight cuts for a construction project or more intricate cuts for a decorative piece, a cut off wheel can give you the accuracy you need.
Speed
Compared to some other cutting methods, cut off wheels are relatively fast. You can quickly cut through sandstone, which can save you a lot of time, especially if you have a large amount of cutting to do.
Challenges and Considerations
Dust
Cutting sandstone with a cut off wheel creates a lot of dust. This dust can be harmful if inhaled, so it's essential to wear proper respiratory protection, like a dust mask or a respirator. You should also work in a well - ventilated area to minimize your exposure to the dust.
Chipping
Sandstone is prone to chipping, especially if the cut off wheel is too aggressive or if the cutting speed is too high. To minimize chipping, you need to use the right wheel and adjust the cutting speed and pressure accordingly.
Other Options for Cutting Sandstone
If you're not sure about using a cut off wheel, there are other options available. For example, a diamond saw blade can also be used to cut sandstone. Diamond blades are very hard and can provide a clean, smooth cut. However, they're usually more expensive than cut off wheels.
