DRILL AMERICA DA29JCOPC 1/16″-1/2″ Cobalt Jobber Drill Bit Set – 1/64” Size Increments (29 Piece)
The Drill America DA29JCOPC is a premium 29-piece cobalt jobber-length drill bit set containing every fractional size from 1/16″ to 1/2″ in precise 1/64″ increments. Manufactured from M35 5% cobalt high-speed steel, these bits are built for drilling tough, abrasive, and high-tensile materials such as stainless steel, hardened steel, titanium, Inconel, and cast iron where standard HSS bits fail quickly. The straw/gold oxide finish adds lubricity and heat resistance, while the heavy-duty 135° split-point design self-centers and penetrates instantly without walking—even on curved or hardened surfaces. All 29 bits are housed in a rugged, rust-proof round metal index with a secure snap-lock lid and clearly marked size slots. This is the ultimate cobalt set for machinists, fabricators, maintenance shops, and serious automotive/motorsport professionals.
