Tungaloy's ETTL Insert Improves Efficiency for Parallel Thread Milling
Thread milling provides a high level of security thanks to the light cutting load generated when the tool breaks the chip in smaller pieces, preventing the chip from being jammed, which typically occurs during tapping.
Tungaloy’s ThreadMilling ETTL indexable thread milling tool
The Tungaloy ETTL model for its ThreadMilling indexable thread milling tool series incorporates double-sided inserts with two cutting edges. The tool enables the production of various standard threads, such as ISO metric threads, Unified threads and Whitworth parallel pipe threads, on modern CNC milling machines and machining centers, using helical interpolation programs. Thread milling provides a high level of security thanks to the light cutting load generated when the tool breaks the chip in smaller pieces, preventing the chip from being jammed, which typically occurs during tapping.
ETTL tools are made in diameters ranging from 17 mm to 30 mm with flute counts of two, three and five. The insert clamping screws are embedded in the tool body so the screws will not come loose when exchanging the inserts. Tungaloy says the clamping force of the insert screws are enhanced over that of the existing ETLN style, improving feed rates and cutting performance. The tool is compatible with CNC programs that are being used for the existing style.
