Reciprocating saw for brick and mortar
With strong carbide teeth this reciprocating saw blade cut clay bricks and autoclaved aerated concrete blocks.
The aggressive tooth setting makes it very fast and self-sharpening teeth prolongs the lifetime of this Turptech reciprocating saw blade.
With the carbide teeth blade reciprocating saw blade it is also much easier to make a straight cut for a door or a window.

Reciprocating saw for brick and mortar
"Think Outside The Circle"
The represents a revolution in cutting technology. Using a unique patented orbital cutting motion with two forward facing blades that combine to perform both a hammering and cutting action, the Brick + Mortar reciprocating saw allows for clear visibility and empowers the professional with the ability to cut square, cut deep, cut dry and cut safe with no flydust. The offers extreme levels of precision, accuracy and control allowing the tool to be used for a wide ranged of applications, from heritage masonry work to electrical installations.
These are some of the ideal applications for the :Reciprocating saw
Toothing brickwork for extensions.
Fast removal of in-built objects such as anchors, wall plates, joists, trusses, frames, sills, beams, lintels, wall units and steps.
Expansion joints and wall section replacement.
Removal of in-built furniture, plumbing and vanities.
Cutting of archways and windows.
The nearly ubiquitous reciprocating saw, otherwise known as a recip or demo saw, is handy in almost any construction and remodeling work. It helps remodelers take out the old before adding the new and, on occasion, is a superb pipe cutting device. But cutting masonry?
Most of us might think of standard carbide grit blades for only light masonry use, but that is changing now. With the assistance of some new blade styles, the venerable recip saw will cut masonry, such as cement block and some brick, almost like butter. It can also clean out mortar in a rush, making disassembly of some kinds of brick, block and other masonry walls or structures quick and relatively easy. Some of the heavy duty — and more costly — new blades can even tackle some kinds of stone.
Our own curiosity was piqued at this claim, so we gathered some Paws Off® Eliminator blades and a couple of chunks of medium-weight slate, and gave cutting a try with the blades chucked in a new Bosch R15 recip saw. (None of these blades, even the lighter duty ones, do well in cheap, consumer's grade reciprocating saws. After all, even light masonry is heavy work.)
With the #16 blade and 12-amp saw, we got reasonable speed and a decent looking cut. Some of the smoother grits should do a neater job, but at a slower pace. Using a reciprocating saw is not a rapid-cut method, though it's considerably faster than we expected. Like other types of masonry saw applications, you do need an absolutely solid method of holding the brick, block or stone. Handholding the material simply won't do.
The Grit Gets It Done
As you can see from the above photo comparing it to a DeWalt DW4843 carbide grit blade, the Paws Off blade is completely different structurally and uses a different abrasive to produce its cuts. It is different enough that Paws Off calls these blades "adaptors" rather than blades. Both blades work for many kinds of material that an ordinary recip saw blade won't touch. Compared to the much smaller grit on the DeWalt carbide blade, the Paws Off blade is a very heavy steel coated with tungsten carbide grit in a large flake form. The company says that both blades will work with many materials, including brick, block and some stone.
Due to these differences, it is unlikely that the DeWalt blades will last as long as the Paws Off blades, but you also need to consider the difference in price. The DW4843 carbide grit 8" blade can be purchased for about $12 for a pack of five. Meanwhile, the Paws Off Eliminator blade is not cheap: $29.99 is the MSRP.
The Eliminator blades work to cut concrete block, brick and some stone. They carry a promise on the sleeve to cut more than 100 brick, a promising number for a busy mason.
There are several other points on the Paws Off blades that make them much different from other carbide grit types. Variation in grit sizes is perhaps the largest difference. For instance, grit #16 does a rough cut job in a rush, while the much finer #24 provides a slightly smoother cut, albeit less quickly. Grits to #220 are available for those instances when a really smooth cut is necessary.
Another feature of the Eliminator blades is cooling slots in the bodies, varying in size with the grit. For example, the #16 grit has a single 2-3/8" long slot, while the #24 has four 1" long slots spaced along the blade's center.
Many masons prefer to use reciprocating saws, or the more rugged alligator saw, over table or cut-off saws. One reason is due to the difference in materials, such as the widespread use of autoclaved aerated concrete (AAC) blocks and softer brick. Another reason is the difference in insulation installation techniques. For many European buildings, the veneer is installed, then a brick is removed from each wall section. Next, the insulation is blown in through the hole, and the brick is replaced and repointed.
Turptech Tools currently has several types of tungsten carbide reciprocating blades specifically tailored for use with many different kinds of materials, from soft to hard masonry.
The saw blades is for use with softer materials, such as AAC block and soft stones, and sports cylindrical teeth.
Waldemar Falkentoft, senior consultant at Turptech Tools, says the orange blade is the top blade, attacking the hardest materials that a person can throw at it.
"The orange blade is the Rolls Royce version of these blades. It has a lot more teeth and a special sharpening action," says Falkentoft. "When you're using the orange blade, it's cutting during the Śpulling' action, but during the Śpush' action of the blade, the teeth are re-sharpened. Compared to the pink one, it's twice as fast, but you have less vibration. You can also use the blade in wood."
Each category of Turptech Tools blades comes in a traditional reciprocating blade width of 3/4", ranging anywhere from 6" to 15-3/4" in length, and a monster 2" width, ranging from 12" to 17-3/4". The 25 combinations of Turptech Tools reciprocating blades available allow masons to choose the perfect blade for any task.
"The standard 3/4" height is useful when you want to cut out a single brick," explains Falkentoft, "but if you, for instance, want to cut out an opening for a new door or window, the 2" high blade is very useful because it helps you keep a straight cutting line."
He also says that, while table and cut-off saws may remain a mainstay on U.S. construction sites, reciprocating saws have certain advantages that shouldn't be overlooked. First, masons only need one reciprocating saw, no matter what size blade is required. A simple switch of the blades quickly adapts the saw to any job. He also notes that reciprocating saws naturally direct dust away from the user, rather than "throwing the material around."
"I think probably the reciprocating saws are easier because you can stand at the exact construction area where you are building, measure the brick or block, and cut it off while you are there, instead of going over to a big table saw to do the work," he says. "Mason contractors and their crews will probably save quite a bit of time."
