The DoTwistBall insert is constructed in a helically twisted structure that fits the seat pocket, which is constructed in a matching helical profile. This twist-clamp system helps maximise insert retention, making DoTwistBall suitable for stable machining in demanding 3D profiling and high-feed machining tasks.
The MJ radius insert geometry is cited as popular among manufacturers profiling mould and die parts. This insert features a large cross-section that has been designed to absorb cutting forces, providing higher reliability and performance over conventional round inserts, says the company. The cutting edge integrates a large inclination angle to promote smooth chip evacuation.
According to Tungaloy, high-feed HJ geometry inserts promote efficient machining through 30% greater cutting depth and feed rate over conventional high-feed inserts. The maximum depth of cut for the existing 04 insert is 1.3 mm, while the newly released 06 insert is suitable for cutting at a depth of 2 mm per pass in operations that include shouldering, facing, slotting, pocketing and helical interpolation.
Two standard grades are available: the AH3135 for steel and stainless steel; and the AH120 for cast iron. The cutter body line-up is available in shank, modular and bore types for all three insert sizes, with various choices of tool reach.
