Drill Press Detail
A typical manual drill press is shown in the figure below. Compared to other powered metal cutting tools, a drill press is fairly simple, but it has evolved into a versatile necessity for every machine shop.


The most adjustable part of the drill press is the vertical movement of the drill bit, since this is the motion that is used in production.

  • The capstan wheel (A) moves the drill head up and down.

  • This movement can be locked (D)
  • and there are point-to-point stops (B) for maintaining a specific length of travel.
  • Gradations marked on the stationary part of the drill press (C) let the operator know where he is vertically.
  • Both the drilling head and table can move vertically and rotate about the vertical guide post (b).
  • The base of the drill press incorporates a work surface similar to the table's for oversize workpieces. The base can be bolted down, but often is not since forces on a drill press do not typically cause it to tip over.
    The drill is powered by an electric motor (I).
Drill Press Work Area Detail
A detail of the work area of the drill press is shown below.


Drilling can be accomplished more accurately on a lathe or mill, although drill presses are much cheaper and more accessible machines.
