 |
YF- finishing
YF for finishing of stainless steel.
Inclination angle design is used to reduce cutting resistance and ensure good chip control. |
 |
 |
LF- finishing
LF grooves for fine to semi-fine machining of stainless steel
Small blade width + large rake angle for improved tip strength.
Curved edge design for stable cutting flow control. |
 |
 |
LV- semi-finishing
V-groove type is suitable for universal machining of stainless steel slender shafts.
No cutting width, open groove design improves cutting sharpness and smooth chip removal. |
 |
 |
LM- semi-finishing
LM for semi-finishing of stainless steel and high temperature alloy.
Variable rake angle and cutting edge width to ensure its sharpness and strength.
Heart-shaped chip breaker with good chip breaking |
 |
 |
LR- roughing cutting action
LR for stainless steel of roughing.
Small rake angle and big cutting edge width with strong corner. • Big chip breaker width and shallow.
Large chip breaker width and shallow chip breaker depth to ensure good chip removal. |
