The DeWalt DW1604 is a high-speed steel drill bit designed for drilling in metal, wood, and plastic. Its 12-inch length provides extended reach for applications requiring deeper penetration, while the 3/16-inch diameter suits general drilling needs. The split-point design starts on contact and prevents the bit from walking, making it easier to maintain straight holes.
The black oxide coating resists wear, and the parabolic flute design improves chip ejection during metal and wood drilling. The 31-degree helix minimizes the over-aggressiveness of a true parabolic flute. This professional-grade bit is built for reliable, everyday use across multiple materials.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically-treated lumber.Your risk from these exposures varies, depending on how often you do this type of work.To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
