Product Description
The Milwaukee 48-20-3902 SDS-Max Drill Bit is a heavy-duty rotary hammer drill bit engineered for high-performance drilling in concrete, reinforced concrete, brick, and masonry. It uses the SDS-Max shank system, which allows quick bit changes and efficient power transfer from the rotary hammer to the bit for faster drilling performance.
The bit features carbide cutting edges and breaker-point technology that crushes material as it drills, helping achieve up to 20% faster drilling speeds compared with standard masonry bits. Its variable flute design improves dust removal from the hole, which helps maintain drilling efficiency and extend tool life.
A reinforced rear guard and durable carbide head increase durability when drilling through hard aggregate or occasional rebar, making the bit suitable for demanding construction environments.
