3/16 In X 12 In Black Oxide Extended Length Drill Bit With 135° Split Point

Discover the Irwin 3/16 in x 12 in Black Oxide Extended Length Drill Bit. This long-reach bit pairs a sturdy 3/16 in diameter with a rugged black oxide finish that resists wear under heavy use. Its 135-degree split point anchors the drill on contact, helping to prevent wandering, while the parabolic flute design accelerates chip ejection for cleaner holes. The tapered web minimizes bit rotation in the chuck, delivering steady, straight drilling through metal, wood, fiberglass, and stainless steel.

Benefits: This extended-length bit provides deep-hole capability without repositioning, and its durable coating extends tool life even in tough materials. The optimized geometry ensures easier starts, smoother operation, and faster chip removal across metal, wood, fiberglass, and stainless steel.

• 135° split point: Self-centering tip that reduces walking on contact for reliable starts in metal and wood.
• Black oxide coating: Increases wear resistance and extends bit life in demanding drilling tasks.
• Parabolic flute geometry: Promotes efficient chip evacuation for cleaner, faster drilling through tougher substrates.
• Tapered web design: Enhances rigidity and minimizes chuck spin for straight, accurate holes.
• Extended length (12 in) with 3/16 in diameter: Long-reach bit ideal for deep holes in metal, wood, fiberglass, and stainless steel.

Why choose this extended drill bit: Built for reliability in professional settings, it combines long reach with a tough finish to handle metal, wood, and composites. The extended 12 inch length allows you to drill deep holes without repositioning, while the precision-ground point and robust coating deliver consistent results project after project. Ideal for shop work and field projects alike, this drill bit offers durability, speed, and accuracy in a single tool.
