DEWALT 21-Piece Drill Bit Set for Plastic, Wood and Metal

These industrial-grade twist-drill bits are cut from super-hard, resilient black oxide, ensuring the ultimate in durability and strength. Each bit features a 135-degree split point for enhanced hole-drilling performance, including quick starts and clean, burr-free holes, making them suitable for use in wood, metal, plastics, and fiberglass.

The DEWALT 21-pack black oxide twist drill bit set is ideal for general-purpose drilling materials like metal, hardwood, softwood, PVC, and fiberglass. The parabolic flute design increases chip ejection in metal and wood drilling applications, while the black oxide coating helps resist corrosion and increase durability, so your drill bits last longer.

The 135° split-point tips drill on contact and prevent walking on the hard surface you're working on. Additionally, the 31° helix reduces the over-aggressiveness of the true parabolic flute, making it ideal for drilling deep holes.

The combination of the super-hard, resilient black oxide construction, the 135-degree split point, and the parabolic flute design ensures that these twist-drill bits provide exceptional performance and longevity. Whether you're working with metal, hardwood, softwood, PVC, or fiberglass, this DEWALT 21-pack set is the perfect tool for all your general-purpose drilling needs.

The black oxide coating not only helps resist corrosion but also increases the overall durability of the drill bits, ensuring they maintain their sharp edges and cutting power even after extended use. The 31° helix further enhances the drilling experience by reducing the over-aggressiveness of the parabolic flute, making it easier to control and maneuver the drill bits, especially when drilling deep holes.

These industrial-grade twist-drill bits are designed to provide exceptional performance and reliability, making them a valuable addition to any professional or DIY toolbox. With their durable construction, enhanced hole-drilling capabilities, and corrosion-resistant coating, these drill bits are sure to become an indispensable tool in your workshop or job site.
