Geared head drill press
drill presses are commonly found in custom shops and special
environments where a heavy duty machine capable of production
drilling and quick setup changes is required. In most cases,
the spindle is machined to accept Morse taper tooling for
greater flexibility. Larger geared head drill presses are
frequently fitted with power feed on the quill mechanism, with
an arrangement to disengage the feed when a certain drill
depth has been achieved or in the event of excessive travel.

Borers are vertical mills that are built to bore holes, and
very light slot or face milling. They are typically bed mills
with a long spindle throw. The beds are more accurate, and the
handwheels are graduated down to .0001" for precise hole
|In a metal
working lathe, metal is removed from the work piece using a
hardened cutting tool, which is usually fixed to a solid
moveable mounting, either a tool post or a turret, which is
then moved against the work piece using hand wheels and/or
computer controlled motors. These (cutting) tools come in a
wide range of sizes and shapes depending upon their
application. Some common styles are diamond, round, square and
lathe with DRO and chuck guard. Sizes vary for the operation
