DeWalt Extra Long Black Oxide Drill Bit

The DEWALT black oxide drill bit has a helix of 31 degrees which minimizes the over aggressiveness of a true parabolic flute. With a black oxide coating and a split point, this is a drill bit with great wear resistance that won't walk across your project.

• Multiple sizes
• Parabolic flute design improves chip ejection in metal and wood drilling applications
• Black oxide coated for greater wear resistance
• 135 Degree split point drills on contact and prevents walking
• Helix is 31 degrees which minimizes the over aggressiveness of a true parabolic flute
