Description
- Premium Black Oxide – Heat treated black oxide finish that holds lubricant better than polished bits. This prevents rusting, reduces friction, and allows for smoother chip clearing
- Industrial Grade HSS – Forged from high quality high-speed steel (HSS), these bits offer a great balance of hardness and flexibility, making them less brittle and less prone to snapping than carbon steel or cobalt for general purpose tasks.
- Split Point Tip: These Adrill bits feature a 135° split point tip that prevents slipping and can help increase drilling speed while ensuring smooth and easy penetration.
- Compatible Materials: steel, carbon steel, iron, aluminum, hard plastics, wood and more, and a wide range of applications such as repair, construction, or woodworking.
