Aircraft length black oxide drill bits are ideal for extra reach and deep drilling applications in metal, wood and PVC. The 135° split point tip delivers a precision start and prevents walking for fast, accurate holes. The 3-flat Secure-Grip™ shank holds the bit firmly in the drill chuck to prevent slipping. Black oxide coating provides lubricity and resists corrosion of the bit. Extended length for hard to reach areas.
