Many tool systems quickly reach their limits when roughing tool steel, stainless steel or even superalloys. LMT Kieninger has redesigned the ACU-Jet Double6 specifically for this purpose and has added the Ø 12 mm indexable insert. The result is a tool which offers maximum stability and process reliability. Due to double-sided use of the cutting inserts up to 12 applications per inserts are possible, the tool is highly efficient.
