We got to see theย Bosch V-Groove diamond bladesย unveiled at the World of Concrete show back in January (read Clint DeBoerโs article on Bosch at World of Concrete 2014). Featuring an optimized diamond formula, this series of blades was engineered with the concept of concrete fracture/fissure repair and restoration in mind. Bosch tells us that the key to the V-Grooveโs performance lies in the metal bond that enables the blade to cut through soft, regular, and hard concrete with fewer blade changes, resulting in clean, deep grooves. In fact, Bosch states that these diamond grinder bladesย will last up to three times longer and deliver twice the speed of competitorsโ offerings. They will work with any Bosch grinder, including theย Bosch AG50-11VSPD Paddle Switch Grinder we reviewed earlier this year.
According to Bosch Project Manager Matt Van, โV-Groove technology is a big step forward for the industry in the important work of concrete restoration. Bosch is the leader in diamond accessories for concrete applications. We take that position seriously, and it drives us to seek solutions that go beyond simply meeting the need. Our goal is the development of superior solutions, and V-Groove meets that standard.โย At Pro Tool Reviews, we get excited when companies like Bosch use innovation to drive industry standards beyond the status quo.
Four sizes are available for the Bosch V-Groove Diamond Blades: 4โณ, 4-1/2โณ, 5โณ, and 7โณ. There are also three varieties to choose from based on the hardness of the material the user is cutting into, as well as a standard round blade for general cutting applications. The standard 7/8โณ bore hole fits both small and large angle grinders, so no specialized equipment has to be purchased to use these blades.
The V-Groove Diamond Blades havenโt hit store shelves yet, but the clearance pricing on several websites for their predecessors leads me to believe they will be available soon. For more information, visit Boschโs website.
