CUTTING TOOLS

!
Explanation of the cutting parameters table
In the following pages you will find the table on the right under
the tools. The cutting speed Vc (m/min) is given under the respective
serial numbers.
In addition, we have given the following feed rates:
Drilling = mm / revolution
Countersinking / counterboring = mm / revolution
Milling / cutting = mm / tooth
Reaming = mm / revolution
Turning = mm / revolution
P = Steel
M = VA
K = Cast iron
NE = Non-ferrous metals
H = Hardened materials
S = Special-purpose alloys
Values printed in bold type = first time use

Note:
All cutting parameters are guideline values and have to adjusted to the individual situation. To this end, it is especially necessary to
ensure adequate cooling, stable clamping of the workpiece and sufficient machine power.

Tap use with coloured rings.
Use of tap drills in the individual material areas is to be
controlled by coloured rings.
TITEX has introduced coloured rings for the four most
important tap material groups: steel, stainless steel,
aluminium, grey cast iron.
The diagram clearly shows the areas of use.
The coloured ring advantages:
internationally understood, simple colour code system
Clear assignment of material, tool and application
Clear: all suitable standard tools at a glance
Simple tool selection in operative environment
Less rejects due to correct tool use
