Bosch has expanded the lineup of its SpeedWave Diamond Blades for concrete and other materials to include a 7 1/4-inch blade with a diamond arbor knockout. The new blade allows users to cut not only with an angle grinder, but also with any worm-drive circular saw.
Features of the Bosch SpeedWave include a wave-shaped ridge along both sides of each segment that reduces blade friction and drag. The design also helps clear dust. In addition, SpeedWave benefits from a center cooling disc. The disc uses the blade’s rotation to draw in air and then evenly distributes it, allowing the blade surface to cool, which increases the blade life. Further, the cooling disc’s unique design and position on the blade help it absorb vibration for a smoother cut.
Also, the new 11258VSR Concrete Drill from Bosch Power Tools and Accessories powers its way through concrete with 1.4 foot-pounds of impact force and a 4.8-amp motor. The drill performs up to 50 percent faster than a high-price-point, two-speed hammer drill when drilling 3/8-inch holes into concrete, all with significantly less impact to the user. And compared to a hammer drill, the 11258VSR offers significant reductions in both noise and vibration. The 11258VSR offers two modes of operation: hammer mode and rotation-only mode.
