Problems in the machining process
Unstable chips cause:⒦
Sudden insert fracturing
ᴤ Low efficiency rate
Flaws in work pieces
ᴤ High scrap rates
Short machine stoppages
ᴤ Difficult to automate
FY and SY chip breakers
for solving your machining
problems.
t Non-tangling of chips is the key to the
Poin successful machining of low carbon steel.

Peninsular dot
Peninsular dot
●Two-stage breaker walls at the peninsular dot point
ensures a good chip shape at low and high feed cutting.
●The wavy cutting edge creates ideally shaped chips
even when copying.
●The combination of a peninsular dot and a wide rake
face results in good chip dispersal.
●The wavy cutting edge creates ideally shaped chips
even when copying.

For Your Safety
aDo not touch cutting edges and chips without gloves. aMachine within the recommended conditions, and replace worn tools with new ones before breakage. aUse protectors such as safety covers and
protective glasses. High-temperature chips can scatter and long chips can be discharged. aAlways take precautions against fire when using water-insoluble coolant. aClamp the inserts and parts firmly with
the wrench or spanner provided.
