Features and Benefits

High speed steel (HSS) provides good wear resistance and can be used in general purpose applications on both ferrous and nonferrous materials.
Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.
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.
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.
