🔪 BOSCH RCB8DG 8-Inch Diamond Grit TPI Reciprocating Saw Blade - Ideal for Cutting Cast Iron and Block Review

Tried to cut concrete with this but it didn't work. It took about 25 minutes to cut 5 inches long and 1.5 inches deep. A stone circular saw is much more efficient and cheaper.

Used to trim shallow roots when digging a drainage ditch. Slowly, but he kept moving, pulling out roots up to 3 inches. It doesn't overheat or break, but it still cuts.

Had to redo the plumbing in the bathroom of a 75 year old house. I didn't have time to play around as the job had to be done in two days. Cut through a 4-inch cast iron pipe in about two minutes.

Tries to cut cast iron sewer pipes. If I continued to use these blades, it would take an hour. Almost cut a pipe. Very disappointed with the performance of the blades, especially for the price paid for them.

When building a fire pit out of a cinder block, I couldn't find all the normal blocks like I could before all the quarantines. I used the blade to create the missing blocks. The blade still worked great after I cut the 6 blocks I needed.

There are several options for cutting pipe, some easier or cheaper than others. Blades like these can be quite expensive but a deal for 20 was ok. Someone mentioned using a grinder and if you have a diamond blade for that and it's cheaper that seems reasonable. I only had a cheap $30 RF reciprocating saw when I did this and it…

There's probably no more expensive way to cut concrete blocks or hardened concrete, but it works. In my situation I had to widen the bypass hole to make getting in and out and moving tools/materials a little easier. Cutting through hardened concrete with this blade is slow and wears out the blade fairly quickly, but there's still some life in it after a few cuts and I think I can probably cut through another brick or two before the blade roasts. There are areas that just can't be cut with a…
