SELECTION GUIDE PARTING PARTING UA/UT-Type • A chipformer for use at low feeds • Recommended for CrNi alloys and low carbon ~12° steel, especially in the bearing industry and on similar, problematic materials 7° • The narrow chipformer design ensures short deformed chips and provides improved performance • UA and UT are similar chipformers. UT is slightly Recommended feed range as a function of insert width tighter than the UA chipformer Feed mm/rev f ≈ W insert [mm/rev] 0.18 40 0.14 0.10 0.06 0.02 Width 2.2 3.0 4.0 5.0 6.0 mm P-Type • Very positive rake inclination and sharp cutting edge 13˚ • For soft materials, slim parts and general parting f ≈ W insert [mm/rev] 7˚ 55 Alloy Austenitic High Temp. Nonferrous Cast Steel Stainless Alloys Materials Iron ✔ ✔ ✘ ✔ ✘ M-Type • Similar to C-type, but with modified edge ~12° • Improved chip control at medium feed f ≈ W insert [mm/rev] 7° 22 Alloy Austenitic High Temp.
