Introducing the Master Mechanic #9 wire gauge drill bit, a 3‑5/8" precision cutter finished in durable black‑oxide. This compact cutter is engineered for fast, accurate starts and delivers clean, burr‑free holes in metal and plastic alike.

Why it matters: The split‑point tip eliminates wobble, letting you drill straight through without wandering. The black‑oxide surface resists wear, prolongs tool life, and promotes smooth chip evacuation for consistent performance on every job.

Key Features & Benefits:
  • Split‑point geometry (135°): Guarantees rapid engagement and reduces walking for superior hole accuracy.
  • Black‑oxide treatment: Provides corrosion resistance, hardness, and enhanced chip flow during drilling.
  • Exact wire‑gauge sizing: Perfect for creating holes that match standard wire‑gauge dimensions, ideal for tapping and thread preparation.
  • Optimized for 1/4‑28 tap range: Enables seamless drilling of pilot holes required for fine‑thread taps.
  • Carded packaging: Keeps each bit securely organized and ready for immediate use.

Ready for precision work: Whether you're building a custom wiring harness or need tight‑tolerance holes for mechanical assemblies, this #9 wire gauge drill bit delivers the consistency professionals rely on. Its robust construction and specialized coating make it a go‑to choice for repeatable, high‑quality drilling tasks.
