Aircraft length drill bits are ideal for extra reach and deep drilling applications in metal, wood and PVC (polyvinyl chloride). Black oxide coating provides lubricity and resists corrosion of the bit. Split point tip delivers a precision start and prevents walking for fast, accurate holes. For drilling through metal, wood, fiberglass, stainless steel.
