Features and Benefits
Straight flute drills are used for drilling holes in hardened and high strength steels over 50 HRC. The straight flute allows for deep hole drilling.
Solid carbide provides better rigidity than High Speed Steel (HSS). It is extremely heat resistant and used for high speed applications on cast iron, nonferrous materials, plastics and other tough-to-machine materials.
Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.
