Product Details

  • BROKEN FASTENER REMOVAL - The left hand drill rotation can cause a fastener to back out while drilling, reducing the need to use screw extractors.
  • SUPERIOR PERFORMANCE - Micro-center stepped drill point eliminates the need for center punching or pilot holes. Tip geometry reduces heat buildup, helping the cutting edges stay sharp. Fast, clean cutting in hard or soft metals is ideal for drilling out broken fasteners.
  • MAINTENANCE LENGTH - Overall length reduced by an average of 15% to provide increased rigidity, strength and breakage resistance.
