■ 2 cutting edge shapes, expanding machining applications
Sharper edge S type and fracture-resistant C type added to the 2D size series.
S Type Sharp Corner: Sharper Edge Design
Gash Land: Fracture-Resistant Design C Type
When using endmills with gash land, some material remains as shown at right. If you need sharp corners, use the S type.
