LMT-Fette is pleased to announce the introduction of our patented, PENTATEC® Multi-Functional Turning tool. This unique, indexable tool is capable of drilling, boring, facing, and turning, without changing tools. Its unique design features a variation on the conventional trigonshaped carbide insert, which is set in a position that allows for drilling of holes down to 8mm (.3159 ), while being capable of performing the additional operations outlined above.

Application Area
The PENTATEC® product is designed to perform the duties of several tools, thus eliminating turret indexes and reducing machining time. The PENTATEC® has a helical geometry, and a large, single helical flute for maximizing chip evacuation. This design allows the PENTATEC® to perform exceptionally as an indexable drill, as well as in deep boring applications where chip evacuation is critical to success.

A typical application for the PENTATEC® tool would be one where the PENTATEC® could start by drilling a hole at the nominal PENTATEC® size. After drilling, the PENTATEC® could then be used to rough and finish the bore, as well as chamfer the bore. After completing the internal work, the PENTATEC® would then go on to face the work piece, then rough and finish turn the O.D.

The result is a work piece that is machined completely with a single tool, and a dramatic decrease in cycle time.

Materials
With a wide range of grades, and two optimized geometries, the PENTATEC® is capable of machining most materials, from carbon and alloy steels, to aluminum, to stainless steel and cast iron. In steel, gear blanks or bearing races can be machined quickly and cost effectively with a single PENTATEC® tool.

Advantages
The primary advantage of LMT-Fette’s new PENTATEC® tool is its ability to perform a wide range of applications without changing tools. Additionally, the PENTATEC® also doubles as the industry’s smallest indexable drill at 8.0mm (.3159 ). Lastly, with its trigon-shaped insert, the PENTATEC® maximizes cost effectiveness by offering three complete edges per insert. All in all, the PENTATEC® tool replaces as many as five tools with a single tool.
