New Kennametal Turning System Has Eight Cutting Edges Per Insert

Kennametal has released the Fix8 heavy-duty turning system, which the company says delivers maximum metal removal rates in steel, stainless steel and cast iron. With eight cutting edges per insert, the Fix8 turning system is said to increase productivity of heavy-duty turning operations while providing the lowest cost per edge and reducing cutting forces up to 15%.

“Fix8 is designed to cover a wide range of applications, including turning and facing, smooth surfaces, interrupted and heavily interrupted cuts. From medium depth-of-cut to roughing in steels, cast iron and challenging materials like stainless steel, Fix8 handles it all. Even extreme feed rates of up to 1.4 mm (0.055") and depths of cut up to 12 mm (0.472") are possible with Fix8,” says Matthew Fuerst, product manager, Kennametal.

The design of the Fix8 insert features a rigid clamping system that pulls the insert securely into the pocket seat, reportedly offering superior stability that enables the insert to withstand large cutting forces and vibrations. The insert is also supported by a replaceable carbide shim, protecting the pocket against deformation and damage.

The Fix8 tool holder features precision 3D coolant technology, supplying sufficient coolant where needed. Three coolant nozzles are directed to the rake face, controlling temperature, chip evacuation and supporting chip formation. Coolant exit holes in two different locations are directed toward the flank of the insert, controlling the heat in the cutting zone and
prolonging tool life.

Fix8 provides excellent chip control for any heavy-duty turning application while increasing tool life. The insert design reduces cutting forces and power consumption, which the company says makes it ideal for low horsepower lathes.
