Guhring - 1.09mm, 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.
