Use-Your-Power-Tools

There are various power tools that you may use to slice the cement board. It will make a lot of dust, so you need to protect yourself using your respirator and goggles. To produce straight cuts, you have to utilize a circular saw with a carbide-tipped blade.

It will draw the saw into the board with moderate and equal pressure. Here’s a tip: you have to use a blade with a few teeth.

A saw with many teeth will get blocked down and make thick dust. When you use a few teeth of the blade, you can cut the durock quickly and smoothly.

Moreover, you may also cut the durock using an angle grinder that comes with a diamond cutting wheel.

However, the tool may give off a lot of dust. Also, it is harder to regulate than using the circular saw. Also, you can get a wet saw, which may cut tiles. The saw comes with an abrasive blade that has water. So, it cuts the tiles smoothly and without dust.

The next equipment you can use is a jigsaw with a metal or carbide-grit blade. You can try cutting the ¼ inch of the cement board with this tool. The saw will slice slowly but smoothly. Also, it will produce only a minimal amount of dust.

Slicing Round Holes

Slicing Round Holes

When you want to create holes in your durock so that it will fit in the toilet flange or tub faucet, you may use a few tricks in this process. A method you can use: sketch the outline of your hole onto the durock using a pencil compass.

Then, throw a ¼ inch masonry bit into the drill. Make a few closely spaced holes around the outline.

Then, get a hammer to tap the hole. After a couple of taps, the board will tear along the opening, and the circle will crack open. You have to clean the ragged edges with the plier or nipper.

Furthermore, you may cut the holes with a jigsaw that has a carbide-grit or metal-cutting blade.

When you use a jigsaw to slice a square or circle hole, you may begin by creating a hole through the cement board using a 3/8 inch drill bit. Then, you have to put the jigsaw blade into the crack and start cutting.

You need to remember that a jigsaw with carbide-grit or metal-cutting blade may give off larger round slices than just the regular straight cuts. So, you need to begin cutting a hole with a drill bit.

Then, you have to utilize the tool to extend it and carry on with the process. When using a jigsaw for the job, it is crucial that you first draw the board using a carpenter’s pencil.

That way, it will guide you all throughout the method. While slicing round holes with a jigsaw, the strategy will allow you to have more custom hole sizes.
