Bosch Sandwich Diamond Blades for Tuckpointing DD510H
The common thickness of a mortar joint is 1/4” and the traditional tuckpointing diamond blade simply makes the blade thicker to fill the entire gap in a single pass. At the time this was a big time saver, however the “sandwich” formation uses 2 blades with a gap to make the same cut and the mortar inbeteen simply falls away because it has nothing to hold onto. This means less mortar to cut, quicker cuts and less expensive tuckpointing wheels. These new Bosch wheels will be available on the Diamond Blades page of Ohio Power Tool along with a wide range of other masonry/concrete cutting accessories.
These blades will work on any grinder, although Bosch also makes the ideal tuckpointing tool 1775E ($299, Ohio Power Tool) which provides a spring loaded guard and dust extraction port virtually eliminating dust and debris from the job. In many cases tuckpoint restoration of old buildings is happening on busy cities streets and in areas near people, with these tuckpointing units it is much safe to work without impacting the health and safety of others. We would strongly recommend using some form of duct collect if you are doing any of this kind of work. Check out this quick video below using both the 1775E and the Bosch DD510H blade to see how much dust it creates, then collects when using the proper system.
By combining tall segments and a superior diamond/metal mix with an ultra-efficient and fast sandwich-blade design, Bosch has created long-lasting tuckpointing blades that are designed to grind more surface area than competitive blades. The addition of 4-1/2” and 5” diameter sandwich blades gives the company a broad offering for use in hand-held grinders.
These eight-segment blades are made exclusively for dry tuckpointing applications. Blade widths are 6.35 mm (¼”) with cutting depths ranging from .75” for 4” blades to 1.25” for 5” 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.
“Our Bosch sandwich tuckpointing blades are built to the highest standards of quality in the industry,” said Matt Van, product manager, diamond blades and bonded abrasives, Bosch. “We’ve talked to tuckpointing professionals from across the U.S. and Canada to develop the right combination of aggressive design and manufacturing excellence to ensure a high-quality, fast and reliable blade every time. This is a critical job on any jobsite; the blades have to deliver.”
Bosch combines copper, iron, nickel and cobalt hard-bond metal powders with high-grade diamonds to create hardened 10 mm segments. These blades have high-diamond content to cut mortar efficiently and ample keyhole gullets to remove discarded cement and other debris.
