1/2" - 1" Cobalt Reduced Shank Drill Bit Set 33 Pieces (1/64" Increments)

The 1/2" – 1" Cobalt Reduced Shank Drill Bit Set includes 33 precision drill bits in 1/64" increments, providing accurate large-diameter drilling for metalworking and fabrication applications. Manufactured from cobalt steel, these drill bits offer superior heat resistance, durability, and extended tool life when drilling tough materials.

Each bit features a reduced 1/2" shank, allowing larger diameter drill bits to be used with standard 1/2" drill chucks found on most hand drills and drill presses. The cobalt construction maintains hardness at high temperatures, making these bits ideal for drilling stainless steel, hardened steel, cast iron, and other hard metals.

The complete size range allows precise hole sizing for demanding shop applications, making this set ideal for machining, metal fabrication, automotive repair, maintenance, and general workshop use.
