FIX8 Heavy-Duty Turning System

Nov. 15, 2021
Kennametal's FIX8 heavy-duty turning system has a tangential design that allows it to sustain far higher loads than traditional designs.

With eight cutting edges per insert, the FIX8 heavy-duty turning system delivers maximum metal removal rates in steel, stainless steel, and cast iron. The system increases productivity of any heavy-duty turning operation, providing low cost per edge while reducing cutting forces up to 15%. It has extreme feed rates of up to 0.055 in. (1.4 mm) and depths of cut up to 0.472 in. (12 mm).


The tangential design of the insert features a rigid clamping system that pulls the insert securely into the pocket seat, offering stability that enables the insert to withstand large cutting forces and vibrations for optimal performance. 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 precisely 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 chip control for any heavy-duty turning application while increasing tool life. The insert design reduces cutting forces and power consumption, making it ideal for any low horsepower lathe.
