• Constructed of M-35 5 percent cobalt high speed steel.

• Cobalt drills normally are amber colored for easy  identification.

• 130-degree cobalt drill bits will substantially outperform 135-degree cobalt drills in working hardening stainless steel and other tough drilling applications.

• High helix provides longer working lifetime and faster feed speed, promotes better chip ejection.

• Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance.

• Specially developed for drilling low tensile strength materials such as aluminum, zinc , soft steels, and some plastics.
