BaseThe heavy foot that supports the whole machine. Bolted down, it stops the press shaking.
ColumnHolds up the head and carries the worktable. A tall, round post.
WorktableThe table the work rests on, on an arm round the column. It moves up and down, swings aside, and on many presses tilts.
HeadThe top of the press, bolted to the column. It holds the spindle, the quill, the motor and the feed mechanism.
MotorTurns the spindle through the belt. An electric motor at the back of the head.
PulleysStepped pulleys on the motor and the spindle. Moving the belt to a different step changes the spindle's speed.
BeltThe drive belt from the motor pulley to the spindle pulley.
Feed handlesThree handles on a hub. Turning them lowers the quill and drill into the work, and raises them again.
Quill (sleeve)The sleeve round the spindle. It does not turn, but slides down to feed the drill into the work.
SpindleThe shaft that turns inside the quill and holds the chuck.
ChuckThe jaws that grip the drill bit.
Drill bitThe cutting tool that bores the hole, gripped in the chuck.
Depth stopAn adjustable stop that sets how far the quill can go down. Every hole is then drilled to the same depth.

How it works
This drill press diagram quiz is on a belt-driven floor model seen from the side, with the belt guard open. The frame and the drive are asked first, then the parts that carry the drill bit down.

Names that get swapped
Three parts hang in a line at the front. The quill is the sleeve coming out of the head, the spindle the thinner shaft below it, and the chuck the wider body under that, gripping the drill bit. The depth stop is the thin rod with two nuts beside the quill; the feed handles are the three spokes on the side of the head.
Head, motor and base
The head is the whole housing on top of the column, and the motor the separate body behind it. The base is the slab on the floor. Its top is similar to a worktable and may be slotted for work too large for the table.
Pulleys is one answer for the two stepped wheels, on the motor and on the spindle. A tap on either counts.
Some shop manuals call the drill bit simply a drill.
Questions and answers
What is another name for a drill press?
Pillar drill, pedestal drill or bench drill. Machine shop manuals say drilling machine. The pillar is the column.
What is the difference between a bench and a floor drill press?
Where it stands: a bench model is mounted on a workbench and a floor model on the floor. Both are built of the same six things: spindle, quill, column, head, worktable and base.
What is a geared head drill press?
One with no belt. Gears inside the head carry the motor's power to the spindle. The quiz is drawn on the belt-driven kind, which is why it asks for the belt and the pulleys.
What holds the bit in a drill press?
The chuck. Its three jaws close on a straight-shank bit when the chuck key is turned, and the chuck's own shank sits in a taper inside the spindle. Larger bits have a tapered shank and are held by a taper socket, not by jaws.
