The world first* feature of the carbide head and carbide holder enables security and rigidity close to that of a solid type end mill. This is made possible because the taper and end clamping faces of the head and the holder, are both solid carbide, only the threaded part is steel. Benefits of this secure and accurate clamping method when compared to the usual steel brazed to carbide method; with all its inherent weaknesses, are greater efficiency from increased cutting parameters, improved accuracy and the important factor of reliability. The iMX exchangeable series of end mills has obvious advantages for reducing inventory levels and tool change times. The primary application area is the machining of titanium alloys and heat resistant alloys such as Inconel. Furthermore, high performance milling of stainless steels, carbon and alloy steels and hardened steels when long overhangs are required. Each head type has irregular helix flutes for vibration control and one of each type incorporates through coolant holes. iMX heads, all with variable helix, are supplied in 12 different geometries - Ø10 ~ Ø25 3 & 4 flute square types, with through coolant 4 ~ 12 flute corner radius types, with through coolant - including 3 flute for aluminium 4 flute roughing type 3 & 4 flute ball nose with through coolant iMX carbide shanks are also provided from - Ø10 ~ Ø25. * According to our research
