• Black oxide finish for increased wear resistance and added lubricity
• 135° split point for fast penetration and accurate starting (self-centering) which eliminates “Walking” and reduces the thrust force needed
• Longer Overall Length but Shorter Flute Length for maximum rigidity
• Used where extra reach is required or for drilling holes in hard-to-reach places
• Ideal for a wide range of materials
