Overview

• Cobalt is harder than high speed steel and provides better wear resistance It is commonly used on high tensile alloys
• Regular, also known as medium spiral bits, are used in general purpose applications They are used on soft, nonferrous materials
• Spiral flute reamers are used in blind and through-hole operations They are used to bridge 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
• Titanium Nitride (TiN) is a multi-purpose coating which increases chip flow in softer materials The heat and hardness resistance allows the tool to run at higher speeds than uncoated tools
