Saw Blades: Making the Cut
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.
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 (¼ 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.
Diamond Vantage introduces the Laser Welded All-Purpose Blade. This is Diamond Vantage’s newest all-purpose blade. It is equipped with new .472-inch (12mm) hybrid notched turbo segments for aggressive cutting of a wide range of materials, from cured concrete to asphalt, and everything in between. The blade also features wedge segments for undercut protection. And the best part? This new blade is proudly manufactured in Irvine, Calif. The company promises performance, competitively priced.
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.
The Husqvarna Banner Line BLM series of masonry blades covers all cutting needs. The series includes four blade specifications. The Gold 1 BLM is perfect for fast, free cutting of various types of brick: dense/hard brick, brick pavers, fired refractory, acid brick and medium-hard brick. The Blue 1 BLM is a general purpose blade for cutting medium-hard to hard brick, stone, hard concrete block and combination brick (80 percent brick, 20 percent block). The Red 1 BLM is another general purpose blade for cutting brick and hard paving block (50 percent brick, 50 percent block), abrasive granite and has a longer life cutting soft brick and fast cutting of block. The last blade in the series, the Red 8 BLM, is perfect for cutting abrasive lightweight block and has a longer life when cutting combination block and soft brick (20 percent brick, 80 percent block). All blades are available in 14 and 20 inches.
MK Diamond Products Inc.
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.
