This isn't your average masonry bit. The Fischer Quatrium D-SDX has four carbide cutting edges instead of the usual two. This design makes drilling into stone, brick, and concrete faster, creates less vibration, and leaves a cleaner hole. The 130-degree carbide tip is heat-resistant and durable for a long life. The vacuum design helps with dust removal, keeping the hole clearer. The centering tip prevents the bit from wandering when you start drilling. It's particularly good for use with cordless impact drills. If you need to drill a lot of holes in tough materials, this 6mm bit is a professional-grade tool that makes the job easier.
