UA/UT-Type
Z-Type
• Cutting edge with high positive rake, suitable for parting
tubes, thin walled parts and for small diameters • A chipformer for use at low feeds
• Recommended for CrNi alloys and low
• Suitable for soft materials carbon steel, especially in the bearing industry
• Excellent for cutting bearing steel and stainless steel and on similar, ductile materials
• Low-to-medium feeds • The narrow chipformer design ensures short deformed
chips and provides improved performance
f ≈ W insert 28 [inch/rev] • UA and UT are similar chipformers. UT is
slightly tighter than the UA chipformer
