General-purpose chipbreaker with balanced performance General-purpose Chip Control
Wear Resistance Chip Control
Balancing wide-ranging chip control and wear resistance
Need to suppress wear and improve cutting edge sharpness
Need to eliminate chip elongation at small depths of cut
Need to extend tool life in high-load cutting

Chip Control
Standard Cutting Edge Sharpness
Interrupted Machining 1st recommendation for interrupted machining Emphasizing machining stability
Ideal for chip control at small depths of cut
Standard shape emphasizing cutting edge sharpness
Need to suppress rapid fractures
Need to suppress resistance at large depths of cut and high-feed regions
Need to reduce cutting resistance at small depths of cut
ESU
EUP
EEM
Small Depth of Cut High-Feed
High-Feed Cutting Edge Sharpness
Large Depth of Cut High-Feed Highest cutting edge strength in the series. Balanced wear resistance and fracture resistance
Good chip control and suppressed resistance at small depths of cut
Good cutting edge sharpness with double positive shape
