Why buyers pick this one

Black Oxide Treatment: Extends the life of the bit by resisting corrosion and holding lubricants better than standard uncoated (bright) drill bits, ensuring cooler and smoother cutting.
Premium HSS Construction: Built to withstand the torque and speed of modern corded and cordless drills, maintaining edge sharpness through hundreds of holes in mild materials.
Precision Flute Design: The engineered spiral flutes rapidly evacuate chips and debris from the hole, preventing binding and burning, especially in deep drilling applications.
Versatile Application: The ultimate "all-rounder" bit. Perfect for maintenance crews, auto-body shops, and general construction where workers encounter wood, plastic, and metal on the same job site.
Massive Sourcing Capacity: Buy direct from the source. We offer complete OEM customization, allowing you to build tailored metric or imperial sets in branded metal index cases or plastic packaging.

Forged from high-quality High-Speed Steel (HSS), these jobber-length bits undergo a specialized Black Oxide surface treatment. This industrial finish not only provides excellent resistance against rust and corrosion but also creates a porous surface that retains cutting fluids, thereby reducing friction and heat buildup during operation.
