Bosch DB442SB3 4 Inch Standard Turbo Rim Diamond Blades 3 Pack for Smooth Concrete Masonry Stone Cutting 7/8 Inch and 5/8 Inch Arbor

Precision Masonry Performance: High-Speed Turbo Rim Diamond Blades for Smooth, Professional Finishes

The Bosch DB442SB3 4-Inch Standard Turbo Rim Diamond Blade 3-Pack is the ultimate solution for contractors and DIYers requiring clean, chip-free results in tough masonry materials. Engineered to outperform and outlast traditional abrasive wheels, these blades feature a continuous turbo rim design that maintains constant contact with the material. This unique geometry produces significantly smoother cuts in concrete, stone, and brick, making it the ideal choice for decorative masonry, tile repair, or any project where finish quality is paramount.

Built for high-heat jobsite conditions, each blade is constructed with a reinforced steel core featuring integrated cooling holes to extend tool life and prevent warping. Bosch utilizes larger, industrial-grade diamonds distributed evenly throughout an optimized metal matrix to ensure aggressive cutting speeds and reliable performance. Whether you are working with a corded or cordless small angle grinder, the included 5/8" bushing ensures compatibility with standard arbors, allowing you to tackle concrete blocks and stone slabs with total confidence and efficiency.

Pro-Tip: To extend the life of your diamond blade, avoid applying excessive pressure. Let the weight of the grinder and the diamond rim do the work. Periodically backing the blade out of the cut for a few seconds allows the cooling holes to circulate air, preventing the steel core from overheating and ensuring the diamonds stay exposed for peak cutting speed.
