Choosing the Hole Saw
It is very important to choose the perfect hole saw to drill your concrete. You can get a carbon steel hole saw at a perfectly cheap rate. This is generally used to cut wood though. Your bimetal hole saw is practically used to cut both wood and metal. But when you are looking to cut through concrete, you need to think of buying a diamond or carborundum grit 3 inch hole saw. This will cut through the concrete perfectly.
Using the Hole Saw
When you are working on concrete with concrete hole saw, here’s how you do it. You should draw a huge circle around the area you are looking to drill. Now begin drilling with your hammer drill; you need to punch holes in here. Once you are done with that, you can clean the whole setup with a side grinder or a diamond blade. You can use the spline shafted with the hole saw to do the whole drilling for you. Make sure you use a 2 and half inch spline for the drilling purpose. This will blend in easily.
Breaking In Your Diamond Saw Blade
One key to ensuring a long life and ease of use for diamond saw blade is knowing how to properly prepare them for use.
First, make several cuts through a soft abrasive material, such as a common red brick.
To start a saw cut on lapidary material, run the saw blade at operating speed and slowly feed your stone into the spinning blade. Watch the initial cut to ensure a straight feed. If the cut isn’t straight, the blade will deflect at the point of contact, producing an uneven cut.
As soon as you notice the blade deflecting, stop the saw, shift the stone slightly and start the process again. If you don’t correct the process immediately and continue to cut, the blade will be dished by the time you finish the cut. If this happens, the blade will require repair or replacement.
