MORSE TAPER DRILLS

• Morse taper drills are used when a hole larger
  than ½ is needed
• Morse taper drills can be used on the mill,
  lathe, and the big drill press in the shop.
• Morse taper drills, sleeves, and drift punches
  are located in the top two drawers on the left
  side of the large grey tool box (3).
• NOTE Do not attempt to chuck Morse taper drills
  into a standard drill chuck. Their tapered shaft
  is not compatible with standard non tapered drill
  chucks.
• This type of drill can be purchased from MSC
  Industrial Supply, or any other supplier that
  sells machine tooling.

• If a drill chuck is inserted into machine, remove
  it by inserting a drift punch into slot and tap
  drift with a lead hammer. Hold drill chuck with
  other hand to prevent it from dropping.
• To assemble Morse drill bit, first wipe the
  tapered part of the shaft to ensure a clean
  surface.
• Next, insert bit into sleeve, mill, lathe, or
  drill press and rotate until flat tab on bit
  falls into slot.

  upside down and tap with medium force onto a hard
  surface once or twice to seat drill bit.
