Hertel - 1/16" to 1/2", Chucking Reamer Set - Straight Flute, Right Hand Cut, 29 Pieces

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

Straight flutes are the most common and are used in general purpose though-hole applications. They are used for reaming holes without interrupted cuts.

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.

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