1/2 X 12 In. High-speed Black Oxide Drill Bit

Introducing the 12‑inch extra‑length 1/2" high‑speed steel drill bit, finished with a durable black‑oxide coating. Its sleek black surface reduces heat buildup while the extended shank reaches deep cavities without sacrificing control. Engineered for precision, this bit delivers rapid entry and smooth chip evacuation, making it ideal for demanding DIY and professional projects.

Why it matters: The combination of a 135° split‑point geometry and four precisely sharpened cutting edges eliminates wobble, ensuring straight holes every time. Whether you’re tackling cabinetry, installing drywall, or fabricating lightweight metal brackets, the bit’s low‑friction finish speeds up the job and extends tool life.

• High‑Speed Steel (HSS) Construction: Provides exceptional hardness and heat resistance for consistent performance in wood, plastic and soft metals.
• Black‑Oxide Tempering: Reduces friction, improves chip flow and prolongs bit lifespan during prolonged drilling sessions.
• 135° Split‑Point Angle: Guarantees fast penetration and minimizes walking on the work surface.
• Four Cutting Edges: Deliver balanced cutting power, producing clean, accurate holes in a single pass.
• Extra‑Length 12" Shank: Reaches deep pockets and thick materials while maintaining steady torque and reduced vibration.

Bottom line: This extra‑length black‑oxide drill bit combines robust HSS durability with smart geometry to tackle wood, plastic, wallboard, plywood and soft metals such as aluminum, brass and bronze. It also handles occasional stainless steel and tougher alloys, offering a versatile solution for both occasional hobbyists and seasoned tradespeople. Upgrade your drill set with a bit that delivers speed, accuracy, and long‑lasting reliability.
