[photo] The Pentatec from LMT Fette can perform drilling, boring, facing, turning and counter boring with a single tool. The tool’s design is based on a variation of the conventional trigon-shaped carbide insert. According to the company’s press release, it is capable of drilling holes down to 8 mm or 0.315". Its helical geometry and flute maximize chip evacutation, which enables it to perform as an indexable drill as well as in boring applications. The tool can drill a small hole and then rough, finish and chamfer the bore. Next, it can rough and finish turn the O.D. of the workpiece face in order to reduce cycle time. Another design feature includes three complete edges per insert. Available in two insert grades and two optimized geometries, the tool can machine steel gear blanks, carbon and alloy steels, aluminum, stainless steel and cast iron.
