How to Cut Sandstone Slabs with Angle Grinder?

Step-1: Collecting Necessary Gear

As you’re going to deal with dust clouds, you better cover yourself as much as possible by getting safety dresses, including dust masks, headphones, gloves, safety glasses, and helmets (optional). After that, make sure you have got the right cutting blade that is diamond-tipped for your angle grinder. 

Step-2: Drawing Chalk Lines

Next, get your hands on the chalk to make lines onto the sandstone slabs where you want to cut through. Feel free to take help from a ruler while marking lines. Check twice to confirm everything is alright. And leaving a space of at least .25 inches for each joint gap will be needed.

Step-3: Positioning the Slab

Now you must position the slab that you want to cut on a surface that is flat as a pancake! Placing it firmly is a must; if not, you won’t make the straight cuts using your angle grinder. If possible, collect an extra sandbag or such a thing that’ll assist in ensuring maximum stability possible. 

Step-4: Estimating the Surrounding

It’s pretty crucial to look for the surrounding where you’re thinking about cutting sandstone slabs. As you may end up with a massive amount of dust while making cuts, ensure to maintain for at least 6.5 feet distance between your and walls, getting plenty of space maneuver. 

Step-5: Let’s Start Cutting It!

After setting up all the nooks and crannies, turn on the blade straight away and start cutting the sandstone slabs at a snail’s pace from one side to another. To maintain adequate stability, I’d say use both of your hands in terms of holding the blade. 

Ensure to press as firmly as down and push pretty gently across the marks you’ve made for. 

Step-6: Hammering the Slab

Turn over your sandstone slab after shutting down the angle grinder. Afterward, hammering the slab is what you’ll do where half-cuts have been created. While hammering, you should notice the slabs are getting broken around the chalk lines. If not, then restart your angle grinder in terms of going over those marks once again. Afterward, you’ll definitely find yourself successful in order to cut sandstone slabs. 

Cutting Wood with Angle Grinder – Tips and Tricks:

• Getting wood carving discs should be your first and most important task while cutting wood with an angle grinder. Although regular blades can cut wood, you won’t get the results you desire for
• Stay away from pushing so hard; instead, you need to cut slowly as there might be a slight chance of accidental kickback. To reduce the risk, ensure to cut following the straight angle.

Cutting Concrete Slab with Angle Grinder -Tips and Tricks:

• First off, the mark those areas which you’re going to cut concrete through an angle grinder.
• Clamping the block should be in a downward position to make precise cuts and that too without any block movement. 
• After creating deep cuts of a couple of inches, chiseling out the loose concrete slab is what you’ll do. Try to keep on doing it till you’ve got what you’re looking for. But make sure you’re gently doing the whole cutting aluminium.
