These DeWALT Power Tools HSS drill bits are designed for drilling into metal, wood, and plastic materials. Featuring a tapered web construction, these bits provide enhanced durability during heavy-duty applications. The black and gold coating serves to inhibit rust and minimize wear over time. The 135-degree split point tip is engineered to prevent bit walking upon contact for accurate starts. To ensure stability during use, the bits include a 3-flats shank design that helps prevent the bit from spinning out within the drill chuck.
