Applications

  • Aircraft and airframe work: reach through ribs, stringers and stacked aluminum panels where a jobber-length bit won’t fit.
  • Automotive and truck work: drill behind brackets, in frame rails and inside body cavities.
  • Sheet metal and fabrication: drill aluminum, mild steel and sheet metal assemblies from a distance.
  • Wood and plastics: drill through framing, cabinets and panels where the chuck can’t get close.
  • Maintenance and repair: reach holes on machinery and equipment without an extension or coupler.

For stainless steel, cast iron, titanium and other hard metals, use our Predator Cobalt 6″ aircraft extension bits.

Usage Tips

  • Start the hole with a short bit of the same size or a center punch, then switch to the 6″ bit to stay on line.
  • Keep the drill straight. Side load can snap the smaller sizes.
  • Use cutting fluid in steel and back the bit out often to clear chips.
  • Run larger sizes slower than smaller sizes.
