Concrete Saw Blades?

Gas powered and not a diamond blade? Does not sound right to me. Does it have a metal blade? If it does are you using water?

My skill saw and a bunch of fiber blades would have done that much.

Diamond blades can help. Some diamond blades are dry, some are wet. I prefer the wet. Keeps the blade cooler and helps remove some of the material.

Some concrete is harder than others.

Just had a standard $6 14 inch abrasive masonry blade. I used water from a garden hose to keep the dust under control.

I rented one a few years ago. About a 14" diamond blade. Made a cut 8" long horizontal by 24" vertical cut through a very solid 6" thick concrete knee wall (had to cut from both sides). Took about an hour and most of that was spent resting as that is one moose of a tool to use down at ground level horizontally. They didn't rent the blade, they charged by the amount worn off it. Micrometered it on check out and back in on return. I somehow must have chipped one tooth as that one caused me to pay for that amount off of all of them. Price was not bad at all. I used a garden hose with a small stream of water running on the blade.

With a fiber blade your doing ok. I have never seen a gas powered saw rented with a fiber blade.

Dave, a cut that size would take about 5 minutes with our diamond blade saw.

Using a diamond blade in concrete is almost like the perverbial hot knife through butter. Get a diamond blade. I'll never go back to the other type!
