Granules improve air quality

3M™ has made available its 3M Smog-reducing Granules. The nonporous, weather-resistant granules can be integrated throughout the surfaces of asphalt shingles to remove nitrogen oxides from polluted air. 3M Smog-reducing Granules are designed with a specialized photocatalytic coating that reportedly is activated by ultraviolet rays to generate radicals and transform nitrogen oxide gases into water-soluble ions, improving air quality.

Grinders have brushless motors

DEWALT® has introduced three small-angle grinders: the 5-inch Slide Switch Small Angle Grinder, the 5-inch/6-inch Paddle Switch Small Angle Grinder and the 5-inch/6-inch Trigger Switch Small Angle Grinder. Weighing 5.3 pounds, the 5-inch Slide Switch Small Angle Grinder reportedly achieves 13 amps and features an E-Clutch® System and Kickback Brake that automatically shut down the tool when a wheel pinch or stall is detected. Two removable mesh screens keep debris from entering the grinder during use, and the grinder's on/off switch has a no-volt release function to help prevent accidental turn-on. The 5-inch/6-inch Paddle Switch Small Angle Grinder and the 5-inch/6-inch Trigger Switch Small Angle Grinder reportedly achieve 13 amps and feature E-Clutch Systems, Kickback Brakes and Lanyard Ready™ integrated connection points for secure tool tethering. All the small-angle grinders have brushless motors that do not require brush changes.
