Nonferrous Cast Steel Stainless Alloys Materials Iron ✔ ✔ ✔ ✘ ✔ JT-Type The JT chipformer design is based on the J-type 5° chipformer with a T-land reinforced frontal cutting edge. • Provides a solution for the intermediate range between the strong and negative C-type configuration and the positive edged J-type chipformer. 7° • Can be used on a wide range of materials, including soft or hard alloy and stainless steel, Recommended feed range as a function of insert width high temperature alloys and also cast iron. • The JT chipformer deforms the chips into compact Feed mm/rev shapes, in the same manner as the J-type, but it can 0.30 be used at higher feeds due to its reinforced edge.
