Saw Blades: Making the Cut

Words: Dan Kamys

Having recently returned from the World of Concrete/World of Masonry show in Las Vegas, I was able to see firsthand the progress that the saw blade industry continues to make, year after year. Durability and long life are ongoing goals. Blades created for specific purposes stole the show, from mortar-removal blades to the latest in tuckpointing-purposed blades. General-purpose blades still are in demand, and even a basic blade packs a wealth of functionality and ingenuity. Following are several saw blades that are new to the market and promise to get the job done better, in less time.

Tuckpointing Sandwich Blade


Deteriorating mortar leads to water seepage, which can ruin the structural integrity of a building. This critical application demands high-quality, long-lasting diamond tuckpointing blades that can withstand a harsh environment. Bosch sandwich tuckpointing blades are built to the highest standards of quality in the industry. By combining tall segments and a superior diamond/metal mix with an efficient and fast sandwich-blade design, Bosch has created long-lasting tuckpointing blades that are designed to grind more surface area than competitive blades. These eight-segment blades are made exclusively for dry tuckpointing applications with blade widths of 6.35 mm (?? inch) and cutting depths ranging from .75 inch for 4.5-inch blades to 1.25 inch for 5-inch blades. Typical applications for tuckpointing blades include mortar removal in brick buildings and grout removal in commercial tile applications that include waste water treatment plants and subway tunnels.

Hilti DS-BB Masonry Diamond Blades

The Hilti DS-BB Masonry Diamond Blades help make a mason’s job easier by providing fast cutting to help get the job done on time. The DS-BB blades are designed to match the RPM and horsepower of stationary saws, thus providing optimum speed and life for the most productivity, and providing fast cutting, long life and more operator comfort. These blades feature tensioned cores, which allow straighter cutting, reduction in waste and improvement of the operator’s quality of work and efficiency. They also improve the work environment for the operator and surrounding workers, because they make less noise during cutting than regular masonry blades.

MK Diamond Products’ MK-742DSL dry-cutting diamond blade is a silent core blade that has been engineered using an arrayed pattern of diamonds that are aligned for maximum abrasion and material removal. The arrayed pattern allows all the diamonds to work in unison, increasing cutting efficiency by 65 percent over conventional blades. The MK-742DSL has the benefit of a Sandwich Core, manufactured with two steel cores laminated with a copper center that provides the greatest sound reduction. This is beneficial on jobsites where controlling the cutting noise level is an issue near schools or hospitals. In addition, a quieter blade reduces the chance of hearing loss for an operator. The silent core also reduces vibration for operator safety and longer blade life. The MK-742DSL has a 10-mm segment height and is available in 14-inch diameters.
