DORMER - 0.62mm, 118° Point, Cobalt Micro Drill Bit

Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.

Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.

Spiral flute reamers are used in blind and through-hole operations. They are used to bridge interrupted cuts.

Regular, also known as medium spiral bits, are used in general purpose applications. They are used on soft, nonferrous materials.

Straight shanks are used for general purpose applications. The shank is smaller than the drill bit diameter. They are used with portable drills and drill presses on ferrous and non-ferrous materials.
