Drill press.

A drilling machine, or drill press, is used to cut holes into or through metal, wood, or other materials . Drilling machines use a drilling tool that has cutting edges at its point. This cutting tool is held in the drill press by a chuck or Morse taper and is rotated and fed into the work at variable speeds. Drilling machines may be used to perform other operations. They can perform countersinking, boring, counterboring, spot facing, reaming, and tapping . Drill press operators must know how to set up the work, set speed and feed, and provide for coolant to get an acceptable finished product.

Machine Details

Safety Instructions


  • Dress appropriately. Remove all watches and jewelry. Safety glasses or goggles are a must.
  • Prior to drilling a hole, locate the hole by drawing two crossing lines. Use a center punch to make an indentation for the drill point to aid the drill in starting the hole.
  • Select the proper drill bit according to the size needed.
  • Select an appropriate size center drill -if necessary.
  • Select a cutting fluid when necessary (e.g. cutting soft metals, aluminum and mild steel)
  • Properly secure the workpiece to the table.
  • Select the correct RPM for the drill bit. Take into account: size of bit, material, and depth of hole to be drilled.
  • Clamp all work securely to the table.
  • Always remove the chuck key immediately after using it. A key left in the chuck will be thrown out at a high velocity when the machine is turned on. Never let the chuck key leave your hand except to put it back into its holder.

Active Use

  • Use an interrupted feed, called peck drilling, to break up the chips being produced.
  • If there is any smoke generated from drilling stop immediately. Excess heat will damage the drill bit causing it to shatter.
  • Pilot holes should be used on holes larger than 3/8” dia. Holes are to be enlarged in no more than 1/4” increments.

Clean Up

  • Clean the drill press and surrounding area when finished.
  • Use a brush, not your hands, to remove chips from the machine. Do not clean up while the machine is running.
  • Never stop a drill press spindle with your hand after you have turned off the machine. Chips often build up around the chuck.
  • Remove burrs from drilled work piece as soon as possible.
  • Keep the floor area clean. Immediately wipe up any oil spills.
