80% Jig Complete Tooling Kit contains

  • 1/8″ Cobalt jobber length drill
  • 5/32″ HSS jobber length drill
  • 1/4″ HSS stub length drill
  • 3/8″ HSS stub length length drill
  • 7/16″ HSS stub length drill

  • 1/4″ carbide endmill 4-flute, 2 1/2″ overall length
  • 3/8″ carbide endmill 4-flute, 3″ overall length (custom made tool)

All of these tools are the standard high quality that machine shops use.  Except for the 3/8 endmill.  The 3/8 endmill is custom made for this jig.  It features a very short flute (.250 loc).  The shorter flute allows the shank to ride along the jig smooth, rather than cut the jig.
