Starx 17" Masonry Reciprocating Saw Blade-2 TPI Demolition Masonry Tungsten Carbide Saw Blades for Cutting Red Brick, Lightweight Brick, Fiber Cement, Aerated Concrete, Porous Concrete, Cinder Block

It is a good saw blade that can cut 12 inches by 12 inches of concrete and about 90% of the saw blade remains.

I had to cut out some block to add a door. I didn't think a grinder would of been as easy to get this accurate in this location. That vertical cut took about ten minutes to cut. It's slow going but it did a nice job.

Bought this to cut through external brick below a storm window facing into a sun room from back of house. Needed to remove the window and remove brick section below it to accept a pre-hung exterior door.This required two cuts on each side of the window, through footer down to slab. I burned through the first blade 1/4 way into the second cut. That was after about 12 bricks and mortar.I bought a second blade and finished the second cut in about 10 minutes., straight and clean. So that represents a tool cost of around $50.00 which seems kind of excessive but -- there are not many blades up to this task and you definitely will not find anything like this at HD.I still have some life in the second blade and plan to use it for some lite concrete work later this year (installing vent in brick wall). May order a third to keep on hand. Over all, good blade, gets the job done.Just keep in mind -- if your application requires ambitious cutting order two (or maybe three).

Blades cut pretty well and last very long especially for what they’re designed to cut. I used the biggest blade to cut about 36” of brick for a door opening. Larger blades transmit more vibrations back to the saw so be prepared for that but these blades are definitely worth it if you have a need.

take it slow

Got mine, looked good. Used it first time 2 month later and now I wish I had a job right away where I had to use it. Was cutting good for the first hour, stopped cutting good I checked the blade and it was garbage. Teeth were broken. Used it for cutting out hole in the wall, wood and drywall. Not what advertised.

I was super impressed! 1 star reviews are made by people attempting to cut concrete. ** I cut 14 linear feet of block and brick foundation wall in my 1938 brick bungalow. I'm no stranger to cutting hard surfaces. In the past I've rented concrete chain saws for cutting windows out in brick but a rental and a new chain can be upwards of $500. Customers usually pick up the bill for the rental in the price of the job. This time it was at my house and I was trying to think of a more cost effective way. I thought I'd give this a try so I bought two of the 17" blades, thinking I'd burn them up, or at least one of them up. However, I didn't even need the back up. Yes it was a bit slower (total of about 2 hours with the sawzall for 14 linear feet / two different window areas). I read a lot of reviews and the main thing I noticed was that people attempted to cut concrete, these are NOT for concrete. They work quite well for brick and are worth the $25.

They cut concrete and make a nice cut. But it is a lot of work. Need to get the cut perfect when starting. Once it is in it works good. Made one cut with some water. Not really needed. All it did was make a mess. And maybe actually slowed the cut down by making a slurry of concrete. Use them dry. But it takes awhile. Cut three big blocks about 7 inches down. Did all three no problem on biggest blade. Still working good. Don’t know if it will go through rebar though.
