Faster bits from DeWalt

DeWalt is launching a new line of industrial-grade, two-cutter Rock Carbide SDS Plus drill bits, as well as a new line of four-cutter SDS Plus drill bits. Available in February 2008, the new Rock Carbide SDS Plus accessories will provide increased durability, bit life and speed for a variety of industrial applications, including drilling holes in concrete. The new bits offer a longerlasting and faster drilling alternative for professional end users.

The four-flute, two-cutter Rock Carbide SDS Plus bits, ranging from 5/32 inches to 1 1/8 inches, are designed for maximum durability and bit life. Each bit sports a carbide tip that is 10 percent thicker than a competitor. It has a thicker core diameter that is three times more durable than a competitor. Additionally, the elongated four-flute helix will pull debris out of the drilled hole and increase the drilling speed.

The new four-cutter, Rock Carbide SDS Plus bits, ranging from 5/8 inches to 1 1/8 inches, are designed with broader shoulders at the head of the bit for increased life. The open head design on the four-cutter allows debris to flow into the flute and out of the hole, which allows the bit to drill 25 percent faster than a competitor. For increased speed the bits have also been equipped with an elongated four-flute helix.
