Overview

• Bright provides a smooth, polished finish on the tool
• It increases chip flow in softer materials such as aluminum, wood and plastic
• 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 flutes are constructed of a higher flute angle to remove chips easier.
