Drill America 7 Piece Cobalt Drill Bit Set, Plastic Pouch Case, DWDCO Series

Drill America DWDCO Series Cobalt Drill Bits are designed for drilling tough materials like cast iron, stainless steel, titanium, and nickel alloys. Their high red hardness allows them to drill at speeds up to 30% faster than standard high-speed steel (HSS) bits. The 135° split point tip provides fast, precise drilling and helps prevent the bit from walking on the surface. These jobber-length bits have a round shank, making them compatible with various drill chucks and tool-holding systems. The gold oxide finish helps identify cobalt steel tools while offering similar performance to uncoated bits. With a right-hand spiral flute design, they efficiently clear chips to prevent clogging. Built to National Aerospace Standard 907, these drill bits deliver reliable performance for demanding applications.
