This drill bit set features a 135-degree split point, designed to prevent slipping when starting on hard materials. The parabolic flute design enhances heat dissipation and extends the lifespan of the bits. Made from industrial M7 grade steel, these bits deliver high-performance drilling in metal, wood, and plastic. They also have an extra hard titanium coating for maximum durability. The set includes jobber-length bits in the following sizes: 1/16″ (2), 5/64″, 3/32″, 7/64″, 1/8″ (2), 9/64″, 5/32″, 3/16″, 7/32″, 1/4″, 5/16″, and 3/8″. The bits are packaged in a molded plastic case, which features a full-length metal hinge pin for added durability. Bit identification is made easy with clear, easy-to-read size markings.
