Tungaloy to Further Enhance its TetraMini-Cut Family for Greater Flexibility

Iwaki, November 2017 – Tungaloy is enhancing TetraMini-Cut, one of the best of its grooving tool family, by adding a substantial number of new items to its TCG18 insert lines.

Compact and offering economical, four-edged geometry, TetraMini-Cut incorporates a rigid insert clamping system that ensures high indexability and accuracy, extending insert life to the maximum level.

This major addition to the TCG18 insert lineup will make TetraMini-Cut an even more flexible series. Wider spectrums of workpiece profiles, materials, and machine setups will now be covered by this expansion, ranging from small and miniature parts in Swiss-type machines to general-lathe grooving and threading applications. The TCG18 insert is available in AH7025, a dedicated grooving grade optimized for extreme resistance to chipping and plastic deformation in order to deliver secure performance and high metal removal rates in the most demanding operations.
