Various Cutting Tools And Their Properties; Roughing Tools (1); Finishing Or Pointed Tools (2); Right (3) Or Left Cutters - Proxxon PD 400 CNC-ready Commissioning Manual

8.2. Various cutting tools and their properties

For various work tasks there are special tools that are optimally co-ordinated to their
respective intended use due to their form. The right choice of tool is thus not only
essential for the perfect quality of the work result, but some machining can only be
done with certain tool forms from the outset.
We will briefly introduce the most important forms:

8.2.1. Roughing tools (1)

are used to wear off as much swarf as
possible in a short time (regardless of the
finish of the work piece surface).

8.2.2. Finishing or pointed tools (2)

are used to achieve a clean surface.

8.2.3. Right (3) or left cutters

are used for longitudinal and face turning
as well as for boring acute angles in right
or left machining direction.

8.2.4. Parting tools (4)

are used to groove flutes and to separate the work pieces.

8.2.5. Threading tools (5)

are used to cut external threads.

8.2.6. Inside turning tools (6)

for boring, i.e. to manufacture cylindrical hollow spaces
