Internal and External Cutting Tools
Cutting Speeds
KOMET has developed an extensive programme of external and internal cutting tools. This
brochure covers the standard design. In addition to these, special tools within this context
can be supplied to suit customers requirements or to suit proposals based on workpieces
to be machined.
KOMET External and Internal Cutting Tools are used on standard lathes, turret lathes, automatic
machines and special machines and also on boring and facing heads and milling
machines.
Because of the simplicity of their design and their high precision and quality, KOMET
Turning Tools have an excellent record both at home and abroad. Several decades of
experience have meant that KOMET is always able to supply high quality tools to meet
every customer requirement.
The steel and carbide grades used undergo a constant accurate inspection procedure in
our special Trials Department.
KOMET produce high quality tools for the highest of demands.
High Speed Steel Grades:
KOMET Tools are produced in high speed steel grades F and H.

Carbide Grades:
The carbide grades P20 and K10 are supplied as standard for KOMET carbide tools.
Recommended values for cutting speeds
Please note: As KOMET tools are used in so many different applications and are also
dependent on machines and range of tasks, we have shown general recommended
values. These will of course vary according to the feed rate used and the diameter of the
workpiece to be machined.
Application details:
The application details shown depend on the environmental and application conditions
(e.g. machine, ambient temperature, use of lubricant/coolant and the machining result
required). These are subject to correct operating conditions, correct application and compliance
with the spindle speed limits given for the tools.
